Thus, it is suggested here that the multitude of resources available on the terminal branches of the newly evolved angiosperm, rain forest trees led to the morphological adaptations of primates of modern aspect.

Opposed to the apes that had fled into the savannah; those apes supposedly shed their fur due to the blazing 1. They had clear primitive characteristics, such as a postorbital bar, convergent eye orbits and larger brains. The notion that direct competition between the groups was crucial is consistent with evidence that gymnosperms will eventually be affected by the rise of angiosperms.
