The Question
Which of the following statements is INCORRECT regarding the phylogenetic clustering and cranial capacities of hominid ancestors?
Options
- A.
Homo habilis was the first human-like hominid with a cranial capacity of 650-800 cc and probably did not eat meat.
- B.
The evolutionary trajectory from Australopithecus to Homo sapiens represents a strict linear anagenetic progression characterized by discrete, non-overlapping gaps in cranial capacity.
- C.
Homo erectus evolved around 1.5 million years ago, possessed a cranial capacity of approximately 900 cc, and probably ate meat.
- D.
Neanderthal man had a cranial capacity of 1400 cc and lived in near east and central Asia between 1,00,000 to 40,000 years back.

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Students often misinterpret the sequential listing of hominid fossils in textbooks as a strict linear evolutionary ladder (anagenesis).
The trap exploits this misconception by suggesting that taxonomic ranks are defined by discrete, non-overlapping gaps in cranial capacity, whereas actual paleoanthropological data shows overlapping clinal variation and mosaic evolution.
