Indeed, when the Martu and other desert foragers were forced to leave their lands between the 1950s and 1970s, surveys showed that 10 to 20 native mammal species went extinct and the numbers of 43 others dropped sharply

The research compellingly argues that “small-scale human societies can actually exist in an ecosystem without damaging it over a very long period of time,” says archeologist Bruce Smith of the Smithsonian National Museum of Natural History. “It’s just wonderful science.”

At this point the idealist swooshes in: ladies and gentlemen, there is nothing but mind! There is no problem of interaction with matter because matter is mere illusion

idealism has its charms but taking it seriously requires an antipathy to matter bordering on the maniacal. Are we to suppose that material reality is just a dream, a baseless fantasy, and that the Big Bang was nothing but the cosmic spirit having a mental sneezing fit?

pan­psychism: even the lowliest of material things has a streak of sentience running through it, like veins in marble. Not just parcels of organic matter, such as lizards and worms, but also plants and bacteria and water molecules and even electrons. Everything has its primitive feelings and minute allotment of sensation.

The trouble with panpsychism is that there just isn't any evidence of the universal distribution of consciousness in the material world.

The dualist, by contrast, freely admits that consciousness exists, as well as matter, holding that reality falls into two giant spheres. There is the physical brain, on the one hand, and the conscious mind, on the other: the twain may meet at some point but they remain distinct entities.

The more we know of the brain, the less it looks like a device for creating consciousness: it's just a big collection of biological cells and a blur of electrical activity - all machine and no ghost.

mystery is quite pervasive, even in the hardest of sciences. Physics is a hotbed of mystery: space, time, matter and motion - none of it is free of mysterious elements. The puzzles of quantum theory are just a symptom of this widespread lack of understanding

The human intellect grasps the natural world obliquely and glancingly, using mathematics to construct abstract representations of concrete phenomena, but what the ultimate nature of things really is remains obscure and hidden. How everything fits together is particularly elusive, perhaps reflecting the disparate cognitive faculties we bring to bear on the world (the senses, introspection, mathematical description). We are far from obtaining a unified theory of all being and there is no guarantee that such a theory is accessible by finite human intelligence.

real naturalism begins with a proper perspective on our specifically human intelligence. Palaeoanthropologists have taught us that the human brain gradually evolved from ancestral brains, particularly in concert with practical toolmaking, centring on the anatomy of the human hand. This history shaped and constrained the form of intelligence now housed in our skulls (as the lifestyle of other species form their set of cognitive skills). What chance is there that an intelligence geared to making stone tools and grounded in the contingent peculiarities of the human hand can aspire to uncover all the mysteries of the universe? Can omniscience spring from an opposable thumb? It seems unlikely, so why presume that the mysteries of consciousness will be revealed to a thumb-shaped brain like ours?

The "mysterianism" I advocate is really nothing more than the acknowledgment that human intelligence is a local, contingent, temporal, practical and expendable feature of life on earth - an incremental adaptation based on earlier forms of intelligence that no one would reg

rd as faintly omniscient. The current state of the philosophy of mind, from my point of view, is just a reflection of one evolutionary time-slice of a particular bipedal species on a particular humid planet at this fleeting moment in cosmic history - as is everything else about the human animal. There is more ignorance in it than knowledge.

males dislike ornamented females because blue badges indicate a potentially negative quality in females. Although both sexes may develop similar ornaments because they share the genes that underlie the phenotype, expressing the ornament can be beneficial in one sex but detrimental in another.

One solution is to have the expression of [ornamentation] regulated by other factors that are already different between sexes,”

the causation and persistence of ornamentation in females” as well as “unambiguous information on fitness consequences of female ornamentation,” he continued. Because both sexes produce testosterone, added Cox, “regulation by testosterone is not a perfect mechanism for complete sex-limitation [of blue badge expression].”

detrimental ornamentation in females is a paradox that “begs the interesting question of why male-typical ornamentation persists in female fence lizards,” said Langkilde. “We plan to follow this up by examining potential benefits associated with these male-typical ornaments in females.”

Chamath Palihapitiya, a venture capitalist who was an early employee at Facebook, said in November that the social network was “ripping apart the social fabric of how society works.”

The new Center for Humane Technology includes an unprecedented alliance of former employees of some of today’s biggest tech companies. Apart from Mr. Harris, the center includes Sandy Parakilas, a former Facebook operations manager; Lynn Fox, a former Apple and Google communications executive; Dave Morin, a former Facebook executive; Justin Rosenstein, who created Facebook’s Like button and is a co-founder of Asana; Roger McNamee, an early investor in Facebook; and Renée DiResta, a technologist who studies bots.

Its first project to reform the industry will be to introduce a Ledger of Harms — a website aimed at guiding rank-and-file engineers who are concerned about what they are being asked to build. The site will include data on the health effects of different technologies and ways to make products that are healthier

“Facebook appeals to your lizard brain — primarily fear and anger,” he said. “And with smartphones, they’ve got you for every waking moment.”

Apple’s chief executive, Timothy D. Cook, told The Guardian last month that he would not let his nephew on social media, while the Facebook investor Sean Parker also recently said of the social network that “God only knows what it’s doing to our children’s brains.”Mr. Steyer said, “You see a degree of hypocrisy with all these guys in Silicon Valley.”

The new group also plans to begin lobbying for laws to curtail the power of big tech companies. It will initially focus on two pieces of legislation: a bill being introduced by Senator Edward J. Markey, Democrat of Massachusetts, that would commission research on technology’s impact on children’s health, and a bill in California by State Senator Bob Hertzberg, a Democrat, which would prohibit the use of digital bots without identification.

Mr. McNamee said he had joined the Center for Humane Technology because he was horrified by what he had helped enable as an early Facebook investor.

Truth About Tech campaign was modeled on antismoking drives and focused on children because of their vulnerability.

He said the people who made these products could stop them before they did more harm.

"Our results challenge the idea that species that have been historically exposed to more variable environments are better suited to cope with climate change," Botero said.

The simple framework that Haaland and Botero describe can be applied to any kind of environmental extreme including flooding, wildfires, heatwaves, droughts, cold spells, tornadoes and hurricanes -- any and all of which might be considered part of the "new normal" under climate change.

"In this case, our model suggests that the typical inhabitants of these places are likely to be more vulnerable to hotter temperatures than to longer or more widespread heat waves."

"While this simple conservation action is unlikely to completely shift the balance from a 'conservative' to a 'care-free' evolutionary response to extreme events, it may nevertheless reduce the strongest vulnerability of these 'conservative' lizard populations," Botero said. "It might just buy them enough time to accumulate sufficient evolutionary changes in their toes and limbs to meet the new demands of their altered habitat."
