Biologist: Many paleontologists have suggested that the difficulty of adapting to ice ages was responsible for the evolution of the human brain. ███ ████ ██████████ ████ ██ █████████ ███ ████ █████ ██████ ███████ ███████ ██ ███ ████ ████ ██ ████████████ ███████ ██ █████ ███████
Summarize Argument: Counter-Position
The author concludes that the difficulty of adapting to ice ages did not affect how human brains evolved. This is based on the fact that most other animal species adapted to ice ages without any evolutionary changes to their brains.
Identify and Describe Flaw
The author assumes that because most other species’ brains were not affected by ice ages, human brains couldn’t have been affected either. This overlooks the possibility that there are relevant differences between humans and most other species that could allow ice ages to affect human brains even when they didn’t affect those other species’ brains.
