The Elements of Evolution (53-11) Hominid Tolerance Adaptation


Quick climate fluctuations invoke tolerance adapta-tion: being able to survive in a wider variety of habitats and climates. For hominids, behavioral facets of adaptive tolerance included flexibility in diet, tool use, and clothing.

As hominids lived in groups under taxing environmen-tal conditions, the demands of sociality also drove mental development. As with phenotype, a combination of prob-lem-solving and social pressures fomented mentotypic evolution.
