Fossil evidence bridges the evolutionary lineage of primates.
The most ape-like ancestral primate was Dryopithecus.
(A) Dryopithecus - Correct: This Miocene-era fossil (15-20 mya) shows fully arboreal, ape-like features.
(B) Ramapithecus - Incorrect: Now considered a synonym of Sivapithecus, more closely related to orangutans.
(C) Australopithecus - Incorrect: These were early hominins with bipedal adaptations.
(D) Neanderthal man - Incorrect: A late Homo species with advanced tool use and culture.
The correct answer is (A) Dryopithecus, representing the ancestral ape morphology before hominin divergence.
