4. Traits coded for by mtDNA are inherited only through mother
mitochondria

5. 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.

34. 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.
