Answer:
The correct answer will be-<em> </em><em>Homo neanderthalensis</em>
Explanation:
The closest ancestor of modern humans which evolved in the Pleistocene age which was around 7 lakh to 3 lakh years is the <em>Homo neanderthalensis</em> or Neanderthals.
The Neanderthals became extinct around 12,000-10,000 years ago by competitive <em>Homo sapiens</em>.
The specimens of Neanderthals are collected from the central and Western Asia and parts of Europe and showed approximately the same cranial capacity which is around 1450-1500 cc.
Thus, <em>Homo neanderthalensis</em> is the correct answer.
