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 is most applicable in this example?
A) phylogenetic
B) ecological
C) morphological
D) biological

Question

Quizplus · Accepted Answer

The question is asking which species concept is most applicable in the case of Neanderthals and Homo sapiens. The fact that there was probably little or no gene flow between the two indicates that they are reproductively isolated, which is a key factor in the biological species concept. The other concepts, such as phylogenetic, ecological, and morphological, may also be relevant in different contexts, but they are not as directly applicable to this specific question. Therefore, the best choice is D) biological.
