Question

The brain capacity of Homo erectus was about
A. 650 c.c.
B. 900 c.c.
C. 1200 c.c.
D. 1400 c.c.
E. 1600 c.c.

Answer 1

Homo erectus (also known as the ‘upright man’) is an extinct species of the human belonging to the Pleistocene epoch. Brain capacity is defined as the actual volume of the brain. The brain capacity varies from genus to genus and species to species. The more the brain capacity, the more advanced is that species.

Complete step by step answer:
The brain capacity is measured in cubic centimeters (c.c.)
Homo erectus has a brain capacity of 900 c.c. , option (B)
The Homo erectus was an evolved species in comparison to most of the earlier hominids. The cranial capacity of Homo erectus was much more in comparison to most of the modern humans of normal intelligence.
The brain capacity of the Homo erectus varies with the population and the maximum brain size was supposed to be achieved early in life, which points out to the shorter childhood and lesser parental care than in modern humans.
The brain capacity also depends upon the height and weight of the species. Homo erectus had a low and flat skull which contributed to the reduced brain capacity in comparison to the modern human.
The increase in brain size is also related with the increase in meat-rich and high calorie diet. The dietary animal fats provide more for the development of the brain in comparison to the fat synthesized by fermenting plant matter.
So, the correct answer is “Option B”.

Additional Information: Homo erectus are among the first human species to exhibit flat face, prominent nose and sparse hair-covered bodies. The main advancement in Homo erectus included the capacity to use fire, ability to hunt and gather in coordinated groups.

Note: The brain capacity of Homo sapiens was around 1650 c.c., whereas the brain capacity of Homo habilis and Homo neanderthalensis were 650 c.c. and 1400 c.c., respectively.
Thus Homo erectus had more brain capacity in comparison to Homo habilis and other ancient species.
