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 analyzed 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 observations suggest that there was probably little or no gene flow between Neanderthals and Homo sapiens, which indicates that they belong to separate biological species. The biological species concept defines a species as a group of organisms that can interbreed to produce viable offspring and are reproductively isolated from other groups.
