There is still some controversy among biologists about whether Neanderthals should be placed within the same species as modern humans or into a separate species of their own. Most DNA sequence data analysed so far indicate that there was probably little or no gene flow between Neanderthals and Homo sapiens. Which species concept describing species relationship between modern humans and Neanderthals is most applicable in these observations?
A) genetic
B) ecological
C) morphological
D) biological

Question

Quizplus · Accepted Answer

The biological species concept defines a species as a group of organisms that can interbreed and produce fertile offspring. Since there is evidence of little or no gene flow between Neanderthals and modern humans, they likely belong to separate species according to this concept. The other concepts listed (genetic, ecological, and morphological) do not necessarily require reproductive isolation to define separate species.
