Question

How does Homo habilis differ from australopithecines?

Answer 1

Hint: Every member of the genus Homo is referred to as human. As the climate becomes drier and cooler it leads to adaptations in humans. There was a constant increase in the size of the brain throughout evolution.

Complete answer:
Evolution of humans is classified as follows:
Homo habilis: Found in East Africa about 2.5 million years ago. At this time australopithecines also disappeared from the record of fossils. Along with the fossils, stone tools were also found. Homo habilis was similar to australopithecines as both were short and bipedal but some differences were also observed. Jaws, teeth and face of Homo habilis were smaller than australopithecines. Also, Homo habilis has a larger brain as they had 50% larger brain than australopithecine.

Homo erectus: Fossil records of Homo erectus were found 1.9 million years ago in East Africa and lasted for around 1.5 million years ago. They were the first to use fire. Body size was bigger and brain size was 50% larger than Homo habilis.

Homo heidelbergensis: Fossil was found in 1907 in Germany and had 90% of the brain of modern-day humans. Body size was smaller than modern man. Large brow ridges and sloping forehead like that of Homo erectus was present.

The difference between Homo habilis australopithecines are like Jaws, teeth and face of Homo habilis were smaller than australopithecines. Also, Homo habilis has a larger brain as they had 50% larger brain than australopithecine.


Note: Australopithecines is the missing link between the line of ape and humans. Homo habilis and australopithecines differ in their cranial capacity as Homo habilis has more cranial capacity approx. 600 cc. Also, Homo habilis has a flat face and a shorter tooth row than Australopithecines. Also, Homo habilis has a protruding jaw .
