  5. DNA is passed from generation to generation, and therefore can tell us about relationships between individuals. CB 34.38

  6. The mutation rate in human mtDNA is one nucleotide change per 20,000 years. OR A difference of one nucleotide between two people indicates a common relative 10,000 years ago. Fig 4

  7. Relationships of different populations using mtDNA ~150,000ya 7 Daughters of Eve, fig. 1

  8. Two hypotheses about the origin of H. sapiens Multiregional hypothesis “Out of Africa” hypothesis

  9. Relationships of different people using mtDNA. 7 Daughters of Eve, fig. 2

  10. There is no genetic definition of race.

  11. The nervous system allows us to perceive the environment while the brain integrates the incoming signals to determine an appropriate response.

  12. Input to brain is filtered. What are you paying attention to?

  23. Is Race Necessarily a Defining Characteristic? Can race be erased? Coalitional computation and social categorization (December 18, 2001) PNAS vol. 98 no. 26 pg 15387–15392 Robert Kurzban, John Tooby, and Leda Cosmideshttp://www.pnas.org/cgi/content/full/98/26/15387

  24. Random Statements My birthday is in April. My birthday is in June. My birthday is in August. My birthday is in January. My birthdayis in February. My birthday is in July. My birthday is in October. My birthday is in May. Can race be erased? Coalitional computation and social categorization (December 18, 2001) PNAS vol. 98 no. 26 pg 15387–15392

  25. Coalition Membership I like orange. Hook em’. Acie Law is awesome. Gig em’. Go Aggies. Kevin Durant is awesome. I like Maroon. Go Horns. Can race be erased? Coalitional computation and social categorization (December 18, 2001) PNAS vol. 98 no. 26 pg 15387–15392

  26. When alternate coalition membership information is introduced, race is ignored. I like orange. Hook em’. Acie Law is awesome. Gig em’. Go Aggies. Kevin Durant is awesome. I like Maroon. Go Horns.

  27. Despite a lifetime's experience of race as a predictor of social alliance, less than 4 min of exposure to an alternate social world was enough to deflate the tendency to categorize by race. These results suggest that racism may be a volatile and eradicable construct that persists only so long as it is actively maintained through being linked to parallel systems of social alliance.

  28. There is no genetic definition of race.
