Q
Ecological intelligence in primates
A
- hominin intelligence and brain size increase theorized as a result of benefits of navigating and foraging in a complex tropical forest ecosystem
- climate change in late miocene may have been a driving force
- many small-brained animals are just as successful as primates in the same complex enviroment
