On the basis of relatively minor morphological differences, some scientists suggest that Neanderthals should be considered a species distinct from Cro-Magnons, the forerunners of modern humans. ███ ███ ████ ████ ███ █████ ████ ██ █████ ███ ██████ ██ ████████ ██████ ██ █████████ ████████████ ████ ██ ███████ ███ ████ ████ █████████ ███████ ██████████ █████████████ ███ ████ ██ ████ █████ ███ ████ █████ ██████████ ███ ███ ████ ██ ███ ████ ███ █████ ████ ████ ████ ████ ███████ ██████ ████ ████████ ████ ████ ████ ███████ ██ ███ ████ ████████ ███ ████ ███ █████████████ ███████████ ███ ███ ██████ ██ █████ ██████ █████ ██ █████████ █████████████
Summary
Some scientists think that Neanderthals are a different species from Cro-Magnons (the ancestors of modern humans) because of relatively minor morphological differences.
Both groups of hominids used exactly the same kinds of tools even in different environments.
The two groups would have used the same tools only if they faced the same daily challenges and met them in the same way.
The behavioral similarity shown in the tool use suggests that the two groups were members of the same species and that the morphological differences were from living in different environments.
Notable Valid Inferences
Cro-Magnons and Neanderthals faced the same daily challenges and met them in the same way.
