Question
Give scientific: Australopithecus is described as a man with ape brain.
✓
Answer
(1) Australopithecus can be considered as a connecting link between ape and man due to the following ape-like and man like characteristics shown by it.
(2) The ape-like characteristics of Australopithecus:
- The jaws and teeth were larger than those of modern man.
- The face was prognathous, i.e. it had a muzzle like slope
- The chin was absent
- The eye-brow ridges projected over the eyes
- Their cranial capacity ranged from 450-600 c.c.
(3) The man-like characteristics of Australopithecus:
- It walked nearly or completely straight due to erect posture.
- The vertebral column had a distinct lumbar curve with broad basin-like pelvic girdle.
- Dentition was man-like with the smoothly rounded parabolic dental arch.
- A simian gap was absent. Australopithecus is therefore, rightly described as a man with ape brain
