Question

why Australopithecus is considered as first ape man​

Answer 1

Answer:

Because they were the first human ape on earth

(2)The ape-like Characteristibrocs Australopithecus:

• (i) The jaws and teeth were larger than those of modern man.
• (ii) The face was prognathous, i.e. it had a muzzle like slope.
• (iii) The chin was absent.
• (iv) The eye-brow ridges projected over the eyes.
• (v) Their cranial capacity ranged from 450-600 c.c.

(3) The man-like characteristics of Australopithecus:

• (i) It walked nearly or completely straight due to erect posture.
• (ii) The vertebral column had a distinct lumbar curve with broad basin-like pelvic girdle.
• (iii) Dentition was man-like with the smoothly rounded parabolic dental arch.
• (Iv) A Simian gap was absent. Australopithecus is therefore, rightly described as a man with ape brain.
