  • we are quite similar to the African apes anatomically and genetically, especially to the chimpanzees and bonobos
  • minor anatomical differences between humans and apes
  • 46 chromosomes
  • longer legs require less up-and-down movement while running and, therefore, reduce the amount of energy needed to move rapidly
  • allow humans to travel farther with the same calorie expenditure
  • changes in the pelvis which unfortunately included a narrower birth canal in females. 
  • A partial evolutionary solution to this birth difficulty for humans was fetuses being born at a less mature stage, when their bodies are smaller.  The trade off is that human newborn babies are more vulnerable.

      This vulnerability translates itself into an immature brain.  In the baby's first year, the brain grows dramatically.  In fact, humans have more synapses (connections between neurons) at this young age than in any other time of life.
  • Evolving a larger brain comes at a steep energy cost.  The human brain uses about 25% of the energy derived from the nutrients that we consume and 20% of the oxygen.
  • HAR1F regulator gene beginning about 6 million years ago
  • 7th and 19th week after conception
  • People have much more complex forms of verbal communication than any other primate species.  We are the only animal to create and use symbols as a means of communication.
  • We also have more varied and complex social organizations.  The most distinctive feature of humans is our mental ability to create new ideas and complex technologies. 
  • mental levels equivalent to a 3-4 year old human child

  • Harvard naturalist E. O. Wilson published his seminal Sociobiology in 1975. The book unleashed a heated debate over whether social behaviors such as altruism or aggression could have a genetic basis, a controversy that helped spur the now vigorous research into such mysteries.

      This is the 'founder' of the very controversial sociobiology theory of human behaviour.

      Biological anthropology is the discipline that uses Darwin's theory of evolution to study man, primates and all of life.
  • Linguistic Anthropology: examines human languages
  • pplied anthropology is simply the practice of applying anthropological theory and or methods from any of the fields of Anthropology to solve human problems
  • Culture is:
  • Learned
  • Patterned
  • •Shared
  • •Adaptive
  • Symbolic
  • At its most basic level, the difference between Culture and culture is in the way they are defined. C
  • lture with a capital C refers to the ability of the human species to absorb and imitate patterned and symbolic ideas that ultimately further their survival
  • Familial culture
  • Every family is different, and every family has its own culture
  • icro or Subculture
  • distinct groups within a larger group that share some sort of common trait, activity or language that ties them together and or differentiates them from the larger group
  • clique
  • Mexican-Americans
  • micro-culture would be the Japanese hip hop
  • Cultural universals
  • Claude Levi-Strauss
  • gender roles, the incest taboo, religious and healing ritual, mythology, marriage, language, art, dance, music, cooking, games, jokes, sports, birth and death
  • tual ceremonies
  • f cultural relativism deny the existence or reduce the importance of cultural universals
  • Language and cognition
  • Society
  • Myth, Ritual, and aesthetics
  • Technology
  • This problem of right and wrong in terms of crossing cultural lines is a big one.
  • intrinsic cultural distinctions that are meaningful to the members of a given society, often considered to be an 'insider’s' perspective.
  • reate bias o
  • Enculturation
  • This process is the way in which we obtain and transmit culture.
  • In the !Kung Bushman tribe they look down upon people who think highly of themselves and who are arrogant. To avoid these characteristics, each child was raised to put down and mock others when they do things such as hunting and other activities.
  • Cultural Transmission
  • Symbols and Culture
  • Symbols are the basis of culture. A symbol is an object, word, or action that stands for something else with no natural relationship that is culturally defined
  • Ethnocentrism
  • Cultural Relativism
  • Ethnography
  • Deconstructing Race and Racism
  • Race was created long ago as a tool to separate humans
  • Deconstructing the social concept of race has been a major interest of Cultural Anthropology at least since Franz Boas's work on race and immigration in the early 1900's.
  • Race is not biological but it's supposed to be a way to classify biological differences by grouping people according to different characteristics that they have
  • There is no biological part of race. It is strictly a concept created by humans to try to better understand differences between us
  • Technology
