11/19/2007 Physical Anthropology: Lecture 16 I. Brains and Time A. Animals with longer life spans are more likely to experience extreme fluctuations and are exposed to more severe crises (ie: drought) B. Test Hypothesis relative brain size is linked to longevity (Allman) 1. Age of longest surviving individual, calculated residuals 2. Fount relative longevity and brain mass is strongly correlated in monkeys, apes, and humans 3. Folivores have shorter lives and smaller brains C. Humans lie close to the regression line and many other brain structures are also related to longevity D. Those brain structures which are not related to longevity are parts of brain devoted to early stages of sensory processing E. These structures are less involved in memory and strategies to cope with environmental variation F. Relationship between brain size and longevity increase with phylogenetic afinit G. Social Brain Hypothesis 1. Descent of Mind—Darwin proposed that evolution of intelligence is linked to social groups 2. 1982—Allman proposed a version emphasizing the role of brain structures involved in social communication 3. 1988—Bryne and Whiten proposed version in the book, “Machiavellian
