  • And what this means is that if you look at a pedigree like this, and for example, here we have a mother and a father, girls are always round, boys are square. And here you'll see the mitochondrial DNA, it's donated to all of the children, but the fact is that these boys, when they mate, when they have offspring, they will no longer pass along her mitochondrial DNA, so it will be lost. And the only way the mitochondrial DNA can be transmitted is through one of her daughters, who in turn, have daughters.
  • Here's some other interesting principles. Mitochondrial DNA passes always from the mother, so when a fertilized egg is formed, Dad gives his chromosomes, but he doesn't donate for any, doesn't donate any mitochondrial DNA.
  • animals are related to one another. This is kind of a fun undertaking. Look at this. Why is it fun? Well it's, it's kind of an amusing idea, how often were cows domesticated during the history of humanity? How often were sheep domesticated? Pigs, water buffalos, and horses. And what you see here is that cattle were domesticated on two occasions, probably once in Western Asia, the middle east, and once in Eastern Asia. Sheep were domesticated twice, all modern sheep following these two families here

  • And that is, certain genes can evolve progressively over a long period of time, because they don't encode vital functions, or they may even be sequences between genes that don't encode phenotype at all. Imagine, for example, we have a situation were here we have a gene which encodes a vital function, like the eye, here's another gene that encodes another function, oh I don't know, a leg. And here we have intergenic sequences. After all, as you have learned by now, more than 96% of the DNA in our genome, doesn't encode proteins, and probably isn't even responsible for regulating genes. So these sequences, right in here, can mutate freely during the course of evolution, without having a deleterious effect on the phenotype of the organism. There's no evolutionary pressure to constrain the evolution of these genes
  • And many of these neutral mutations, which have no effect on organismic fitness, but are simply evolutionary neutral, are sometimes called polymorphisms. The term polymorphism, -morph is once again morphology, derives from the fact that species tend to be polymorphic, we don't all have blond hair, we don't all have brown eyes.
  • If you look at two chimpanzees living on opposite sides of the same hill in West Africa, they are genetically far more distantly related to one another, than any one of us, by a factor of 10 to 15. Two chimpanzees, they look exactly the same, they have the same peculiar habits, but they're genetically far more distantly-related than we are to one-another, than I am to any one of you, or than any one of you is to one another. And what does that mean? It means that, roughly speaking, the species of chimpanzees is, at least, 10 or 15 times older than our species are. We're a young species, chimpanzees probably first speciated three or four million years ago, if the paleontological record is, is accurate. Paleontology is the study of old, dusty bones, so you can begin to imagine when chimpanzee bones become recognizable in the earth.
  • And what you see already, in such small populations, is that for example, this male here has two girls, and right away, to the extent he had an interesting Y chromosome, that Y chromosome was lost from the gene pool. This girl, here, had an interesting mitochondrial DNA, but right away that's lost, because she has, she has just two boys. And what you see, in very rapid order, in small populations, there's a homogenization of the genetic compliment, just because the alleles are lost within what's called, genetic drif
  • And if you ask that question, the answer is that we all had a common ancestress who lived about 150,000 years ago. All of us trace our mitochondrial DNA to her. Does that mean that there was only one woman alive there, she's called, Mitochondrial-Eve, again, we don't know her name. Does that mean there was only one woman alive, well it doesn't mean that at all because of what I just told you, in small populations the proto-human population.
  • How much are all of our mitochondrial DNA are related to one another, how distantly related are they to one another, given the rate of evolution of mitochondrial DNA sequences?
  • So where do we all come from, all of us human beings? How closely related are we to one another? Here's, here's a measurement of the distances between different mitochondrial DNA's from different branches of humanity. And what you see is something really quite extraordinary and stunning. Here, you'll see that the people, the non-African lineages here and here, are actually relatively closely related to one another.
  • And by the way, all the genes that are present here, the alleles that are present here, can also be found in Africa, but in relatively small proportions in Africa
    • Erin Hamson
       
      Suggesting that all people came from Africa
  • So, what happens there, that's a testimonial to the tragic fate of the Indians, where the conquistadors from Spain came in, killed all the men, and took all the women, to be their brides. How else can you explain the fact that there's no Indian Y chromosomes, there's all, there is instead only European Y chromosomes.
  • When you do genetic counseling of family these days, one of the strictures is, that you never tell the family if the children have genetic polymorphisms that don't match that of the person whom they think is their father. They don't look like their, the person whom they regard as father, but that's always assumed to be a role of the genetic dice.
  • Here's a fun story I like to tell each year, and it's about the Cohen and Y chromosome, and you'll see what an amusing story this is, just from genetics. Now the name Cohen, in Hebrew means, a high priest, and you've heard people named Cohen, it's not such an uncommon name among the Jews. And it says, in the Bible, in Genesis and Exodus, that all the high priests in the Bible are the descendants of Aaron, the brother of Moses.
  • hen it should be the case that all male Cohen's should have the same Y chromosome, right?
  • Because keep in mind, any single affair with the milkman or the mailman, over 3,000 years, would've broke this chain of inheritance, any single incidence of non-paternity. It's a really astounding story, and it's hard, there can be no artifact to it, there's no bias in it, there's no other way to explain it.
  • And what they found was that all members of the, almost all members of the ruling cast among the Lembas, had the same Y chromosome, and the Y chromosome had exactly the same polymorphisms of the Cohen Y chromosome
  • What I'm telling you is that these two genes are totally interchangeable, that they are effectively indistinguishable from one another, functionally they have some sequence relatedness, but in terms of the way they program development, they are effectively equivalent. And what this means is that the progenitor of these two genes must've already existed at the time that the flies and we diverged, which six or seven-hundred million years ago, and in the intervening six or seven-hundred million years, these genes have been totally unchanged.
  • once the gene was developed, evolution could not tinker with it, and begin to change it in different ways, ostensibly because such tinkering would render these genes dysfunctional, and thereby would inactivate them, thereby depriving the organism of a critical sensory organ.

      The process of specialization was later perfected by Henry Ford, in making cheap, durable cars.
  • This great increase of the quantity of work which, in consequence of the division of labor, the same number of people are capable of performing, is owing to three different circumstances; first, to the increase of dexterity in every particular workman; secondly, to the saving of the time which is commonly lost in passing from one species of work to another; and lastly, to the invention of a great number of machines which facilitate and abridge labor, and enable one man to do the work of many....
  • Man has almost constant occasion for the help of his brethren, and it is in vain for him to expect it from their benevolence only. He will be more likely to prevail if he can interest their self-love in his favor, and show them that it is for their own advantage to do for him what he requires of them. Whoever offers to another a bargain of any kind, proposes to do this. Give me that which I want, and you shall have this which you want, is the meaning of every such offer; and it is in this manner that we obtain from one another the far greater art of those good offices which we stand in need of. It is not from the benevolence of the butcher, the brewer, or the baker that we expect our dinner, but from their regard to their own interest.

  • In order to avoid the inconvenience of such situations, every prudent man in every period of society, after the first establishment of the division of labor, must naturally have endeavored to manage his affairs in such a manner as to have at all times by him, besides the peculiar produce of his own industry, a certain quantity of some one commodity or other, such as he imagined few people would be likely to refuse in exchange for their produce....It is in this manner that money has become in all civilized nations the universal instrument of commerce, by the intervention of which goods of all kinds are bought and sold, or exchanged for one another....

Rene Descartes perceptions of philosophy - 0 views

  • As Descartes said, “Those who set about giving precepts must esteem themselves more skilful than those to whom they advance them”
  • In other words, someone might alter the truth solely so they could come up with something to say, while the real truth might not be capable of being expressed so easily, it can only be observed. Some things in life are too complicated to express, but however there are going to be people who believe they can express those things, even though they cannot accurately do so.
    • Brian Earley
       
      I have read scientific journals wherein the author reports on complex interactions or relationships on the molecular level. Often I believe that they really cannot accurately do so. Perhaps scientific journals would be better if they were accompanied by videos. That would make them more like blog posts.

  • are the emotions which are based off of your opinions even real, since they are based off of opinions?
  • Your perception is going to determine what it is that you feel, that is, your conscious and unconscious perception of what is going on is
  • For it seemed to me that I might meet with much more truth in the reasonings that each man makes on the matters that specially concern him, and the issue of which would very soon punish him if he made a wrong judgment, than in the case of those made by a man of letters in his study touching speculations that lead to no result, and that bring about no other consequences to himself excepting that he will be all the more vain the more they are removed from common sense, since in this case proves to him to have employed so much more ingenuity and skill trying to make them seem probable.
  • More especially did I reflect in each matter that came before me as to anything that could make it subject to suspicion of doubt, and give occasion for mistake, and I rooted out of my mind all the errors that might have formerly crept in. Not that indeed I imitated the skeptics, who only doubt for the sake of doubting, and pretend to by always uncertain; for, on the contrary, my design was only to provide myself with good ground for assurance, and to reject the quicksand and mud in order to find the rock or clay.”
  • since emotional intelligence is not completely concrete, it can be subject to skeptics
  • “how do I know that anything is even real”
  • Accordingly I shall now suppose, not that a true God, who as such must be supremely good and the fountain of truth, but that some malignant genius exceedingly powerful and cunning has devoted all his powers in the deceiving of me; I shall suppose that the sky, the earth, colors, shapes, sounds and all external things are illusions and impostures of which this evil genius has availed himself for the abuse of my credulity…”
  • I am, I exist. This is certain. How often? As often as I think. For it might indeed be that if I entirely ceased to think, I should thereupon altogether cease to exist. I am not at present admitting anything which is not necessarily true; and, accurately speaking, I am therefore [taking myself to be] only a thinking thing, that is to say, a mind, an understanding or reason-terms the significance of which has hitherto been unknown to me. I am, then a real thing, and really existent. What thing? I have said it, a thinking thing
  • So it really is thought that makes him who he is, since he is thinking about himself all of the time, in addition to thinking about and in regular life.
  • Thought determines who someone is because your thoughts are controlled, and all your thoughts over your lifetime caused your emotional development, which causes you to be who you are.
  • So it is easy to say that your thoughts understand and/or control who you are, but it is much harder to say that your emotions understand and/or control who you are.
  • I recognize it is impossible that He should ever deceive me, since in all fraud and deception there is some element of imperfection. The power of deception may indeed seem to be evidence of subtlety or power; yet unquestionably the will to deceive testifies to malice and feebleness, and accordingly cannot be found in God.

This is to have succeeded”

      The conclusion for me from this commentary is that thoughts are what make us who we are. Therefore, we must put a lot of our energy into controlling our thoughts so we can become what we want to be.

      and then this other paragraph begins the division
  • If one reflects somewhat upon the connection that discoveries have with one another, it is readily apparent that the sciences and the arts are mutually supporting, and that consequently there is a chain that binds them together. But, if it is often difficult to reduce each particular science or art to a small number of rules or general notions, it is no less difficult to encompass the infinitely varied branches of human knowledge in a truly unified system
  • We can divide all our knowledge into direct and reflective knowledge. We receive direct knowledge immediately, without any operation of our will; it is the knowledge which finds all the doors of our souls open, so to speak, and enters without resistance and without effort. The mind acquires reflective knowledge by making use of direct knowledge, unifying and combining it.

  • Let us sto
  • p here a moment and glance over the journey we have just made. We will note two limits within which almost all of the certain knowledge that is accorded to our natural intelligence is concentrated, so to speak. [34] One of those limits, our point of departure, is the idea of ourselves, which leads to that of the Omnipotent Being, and of our principal duties. The other is that part of mathematics whose object is the general properties of bodies, of extension and magnitude. Between these two boundaries is an immense gap where the Supreme Intelligence seems to have tried to tantalize the human curiosity, as much by the innumerable clouds it has spread there as by the rays of light that seem to break out at intervals to attract us. One can compare the universe to certain works of a sublime obscurity whose authors occasionally bend down within reach of their reader, seeking to persuade him that he understands nearly all. We are indeed fortunate if we do not lose the true route when we enter this labyrinth! Otherwise the flashes of light which should direct us along the way would often serve only to lead us further from it. The limited quantity of certain knowledge upon which we can rely, relegated (if one can express oneself this way) to the two extremities of space to which we refer, is far indeed from being sufficient to satisfy all our needs. The nature of man, the study of which is so necessary and so highly recommended by Socrates, is an impenetrable mystery for man himself when he is enlightened by reason alone; and the greatest geniuses, after considerable reflection upon this most important matter, too often succeed merely in knowing a little less about it than the rest of men. The same may be said of our existence, present and future, of the essence of the Being to whom we owe it, and of the kind of worship he requires of us. Thus, nothing is more necessary than a revealed Religion, which may instruct us concerning so many diverse objects. Designed to serve as a supplement to natural knowledge, it shows us part of what was hidden, but it restricts itself to the things which are absolutely necessary for us to know. The rest is closed for us and apparently will be forever. A few truths to be believed, a small number of precepts to be practiced: such are the essentials to which revealed Religion is reduced. Nevertheless, thanks to the enlightenment it has communicated to the world, the common people themselves are more solidly grounded and confident on a large number of questions of interest than the sects  [35] of the philosophers have been.
    • Erin Hamson
       
      The role of religion is to fill in the gaps that man cannot discover on his own. The difference for us is that someday we will know.
  • The advantage men
  • found in enlarging the sphere of their ideas, whether by their own efforts or by the aid of their fellows, made them think that it would be useful to reduce to an art the very manner of acquiring information and of reciprocally communicating their own ideas. This art was found and named Logic. It teaches how to arrange ideas in the most natural order, how to link them together in the most direct sequence, how to break up those which include too large a number of simple ideas, how to view ideas in all their facets, and finally how to present them to others in a form that makes them easy to grasp. This is what constitutes this science of reasoning, which is rightly considered the key to all our knowledge. However, it should not be thought that it [the formal discipline of Logic] belongs among the first in the order of discovery. The art of reasoning is a gift which Nature bestows of her own accord upon men of intelligence, and it can be said that the books which treat this subject are hardly useful except to those who can get along without them. People reasoned validly long before Logic, reduced to principles, taught how to recognize false reasonings, and sometimes even how to cloak them in a subtle and deceiving form. [38]

      The last couple sentences are interesting because they talk about the human perspective timeline, how we seem to think that simply because something was recently discovered doesn't mean it didn't exist before then. Atom for examplke have always existed but we only recently have begun to discover their true nature.
  • Too much communication can sometimes benumb the mind and prejudice the efforts of which it is capable. If one observes the prodigies of some of those born blind, or deaf and mute, one will see what the faculties of the mind can perform if they are lively and called into action by difficulties which must be overcome.
  • The science of communication of ideas is not confined to putting order in ideas themselves. In addition it should teach how to express each idea in the clearest way possible, and consequently how to perfect the signs that are designed to convey it; and indeed this is what men have gradually done.
    • Erin Hamson
       
      The importance of both sharing ideas, for the general benefit of man, and discovering things on our own, for our progression.
  • The general system of the sciences and the arts is a sort of labyrinth, a tortuous road which the intellect enters without quite knowing what direction to take. Impelled, first of all, by its needs and by those of the body to which it is united, the intelligence studies the first objects that present themselves to it. It delves as far as it can into the knowledge of these objects, soon meets difficulties that obstruct it, and whether through hope or even through despair of surmounting them, plunges on to a new route; now it retraces its footsteps, sometimes crosses the first barriers only to meet new ones; and passing rapidly from one object to another, it carries through a sequence of operations on each of them at different intervals, as if by jumps. The discontinuity of these operations is a necessary effect of the very generation of ideas. However philosophic this disorder may be on the part of the soul, [57] an encyclopedic tree which attempted to portray it would be disfigured, indeed utterly destroyed.
  • It is only after having considered their particular and palpable properties that we envisaged their general and common properties and created Metaphysics and Geometry by intellectual abstraction. Only after the long usage of the first signs have we perfected the art of these signs to the point of making a science of them. And it is only after a long sequence of operations on the objects of our ideas that, through reflection, we have at length given rules to these operations themselves.

  • "We later learned that it was this revolutionary business model. I think the reason it's so pure like that is the reason it's worked so well as a crowdsourcing company."
  • "I think that the way companies are seeing crowdsourcing is a lot different from the way we see it. They are looking at it as this new business model, as a way to outsource your work to an anonymous crowd of people. We're more about giving people something productive to do with their passions."
  • it's not so much the software that makes the company, it's the community
  • "It's an affordable way to be ahead. You're able to see what your customers are thinking and what they're dreaming of, and you're able to measure that against what you're doing."
  • His concern is that by "mining" the crowd in this way, the wealth that results from the work done remains concentrated in the hands of the people who put out the call - ultimately endangering jobs and the economy. Mr Lanier also believes that crowdsourcing threatens creativity.

Pragmatism (similar to cognitivism) states that reality is interpreted, and knowledge is negotiated through experience and thinking. Interpretivism (similar to constructivism) states that reality is internal, and knowledge is constructed.
  • Behaviorism states that learning is largely unknowable, that is, we can’t possibly understand what goes on inside a person (the “black box theory”)
  • Cognitivism often takes a computer information processing model. Learning is viewed as a process of inputs, managed in short term memory, and coded for long-term recall.
  • Constructivism suggests that learners create knowledge as they attempt to understand their experiences
  • Constructivism assumes that learners are not empty vessels to be filled with knowledge. Instead, learners are actively attempting to create meaning. Learners often select and pursue their own learning. Constructivist principles acknowledge that real-life learning is messy and complex.

  • We can no longer personally experience and acquire learning that we need to act. We derive our competence from forming connections.

  • Nodes that successfully acquire greater profile will be more successful at acquiring additional connections

  • Connectivism is the integration of principles explored by chaos, network, and complexity and self-organization theories.
  • Learning and knowledge rests in diversity of opinions.

  • example of a Maricopa County Community College system project that links senior citizens with elementary school students in a mentor program. The children “listen to these “grandparents” better than they do their own parents, the mentoring really helps the teachers…the small efforts of the many- the seniors – complement the large efforts of the few – the teachers.” (2002). This amplification of learning, knowledge and understanding through the extension of a personal network is the epitome of connectivism.
  • Implications
  • The pipe is more important than the content within the pipe. Our ability to learn what we need for tomorrow is more important than what we know today. A real challenge for any learning theory is to actuate known knowledge at the point of application.
  • acknowledges the tectonic shifts in society where learning is no longer an internal, individualistic activity

    What if lectures and course content was experienced through online videos, and when you came together in class you worked on homework and got help from the instructor and fellow classmates? That's what this is all about. An interesting model.

      Social reading -- sounds exciting. I've been thinking how cool it would be to have a class group textbook online. SO like you go online to yoru textbook for your class and you can see what other classmates have highlighted and commented on and tagged and add your own thoughts to the discussion. They can link to their blog posts about a subject in teh book that they did expanded self-directed learning on or just that they thought about more, etc. Sounds SUPER cool, huh? (ok ok, I'll blog about it)

  • How can we achieve clear outcomes through distributed means? How can we achieve learning targets when the educator is no longer able to control the actions of learners?

Understanding Digital Civics | DMLcentral - 0 views

  • it would also be a mistake not to take seriously the role of new communications media in understanding civic life. In democratic states, citizens need information about what challenges a government faces and what it’s proposing to do about it to be effective citizens. And citizens need to be able to connect with one another to discuss, debate and propose solutions. What a communications medium makes possible has a shaping influence on civic life.

LDS.org - Ensign Article - Focus and Priorities - 0 views

  • principle of accountability also applies to the spiritual resources conferred in the teachings we have been given and to the precious hours and days allotted to each of us during our time in mortality.
  • The significance of our increased discretionary time has been magnified many times by modern data-retrieval technology. For good or for evil, devices like the Internet and the compact disc have put at our fingertips an incredible inventory of information, insights, and images. Along with fast food, we have fast communications and fast facts. The effect of these resources on some of us seems to fulfill the prophet Daniel’s prophecy that in the last days “knowledge shall be increased” and “many shall run to and fro”
  • homely story

  • “Do you think we need a bigger truck?”
  • our biggest need is a clearer focus on how we should value and use what we already have.
  • But to what purpose?
  • “knowledge of words, and ignorance of the Word,” in which “wisdom” is “lost in knowledge” and “knowledge” is “lost in information”
  • We have thousands of times more available information than Thomas Jefferson or Abraham Lincoln. Yet which of us would think ourselves a thousand times more educated or more serviceable to our fellowmen than they?
  • I could never complete my assigned task within the available time unless I focused my research in the beginning and stopped that research soon enough to have time to analyze my findings and compose my conclusions.
  • we must begin with focus or we are likely to become like those in the well-known prophecy about people in the last days—“ever learning, and never able to come to the knowledge of the truth” (2 Tim. 3:7).
  • But a bale of handouts can detract from our attempt to teach gospel principles with clarity and testimony.
  • Stacks of supplementary material can impoverish rather than enrich, because they can blur students’ focus on the assigned principles and draw them away from prayerfully seeking to apply those principles in their own lives.
  • Each of us should be careful that the current flood of information does not occupy our time so completely that we cannot focus on and hear and heed the still, small voice that is available to guide each of us with our own challenges today.
  • Our priorities determine what we seek in life.
  • “a man’s life consisteth not in the abundance of the things which he possesseth”
  • Our priorities are most visible in how we use our time.
  • Good choices are especially important in our family life. For example, how do family members spend their free time together? Time together is necessary but not sufficient.
  • I believe many of us are overnourished on entertainment junk food and undernourished on the bread of life.

    Available information wisely used is far more valuable than multiplied information allowed to lie fallow.

  • it’s impossible to overstate the importance of peer production to the modern digital world.
  • What sounds on the face of it like the most utopian of collectivist fantasies — millions of people sharing their ideas with no ownership claims — turns out to have made possible the communications infrastructure of our age.
  • Peer networks laid the foundation for the scientific revolution during the Enlightenment, via the formal and informal societies and coffeehouse gatherings where new research was shared. The digital revolution has made it clear that peer networks can work wonders in the modern age.

  • We have an endless supply of folklore about heroic entrepreneurs who changed the world with their vision and their force of will. But as a society we lack master narratives of creative collaboration.

Dear Internet: It's No Longer OK to Not Know How Congress Works - 1 views

  • the federal government is not attached to Moore's Law
  • Here's an area for both some disruption and some lobbying. Let's build tools that allow members of Congress to aggregate messages being sent to them, and to associate those messages with congressional districts. Let's come up with a way for a member to see what their constituency is saying about any particular issue they'd like, and let's provide that as an open service so that anybody can see what a particular constituency is saying. That way, when a member has a track record of voting against the desires of a substantial portion of his or her district, we've got a record of it, and it can get brought up in the next election.
  • Right now, your voice online -- in the mediums you participate in, not only don't matter: legally they can't matter. Online identities don't count when it comes to the official record
