Best answer

Answer: Australopithecus → Homo erectus → Neanderthal man → Homo sapiens, i.e. (c) → (d) → (b) → (a).

StageApproximate cranial capacity
(c) Australopithecusabout 450–600 cc
(d) Homo erectusabout 900–1100 cc
(b) Neanderthal manabout 1400 cc
(a) Homo sapiens (modern man)about 1450 cc

Cranial capacity increased steadily during human evolution, from the small-brained Australopithecus to modern man. (Some estimates give individual Neanderthal skulls a slightly larger brain case than the modern average, but the expected sequence follows the course of evolution.)
