Question

Using your knowledge of hominid evolution, which of the following correctly associates the given brain capacities with the hominid species in the table in order from smallest to largest?

H. neanderthalensis, H. habilis, A. africanus, A. afarensis


A. afarensis, A. africanus, H. habilis, H. neanderthalensis


A. afarensis, A. africanus, H. neanderthalensis, H. habilis


H. habilis, A. afarensis, A. africanus, H. neanderthalensis

Answer 1

Answer;

-A. afarensis, A. africanus, H. habilis, H. neanderthalensis

Explanation;

-The expansion of the hominid brain begun with the genus Homo. The brain of the earlier hominid genus Australopithecus had a volume of about 400 cubic centimeters, not much larger than that of the great apes.

-Throughout human evolution, the brain has continued to expand. Estimated average brain masses of A. afarensis (435 grams (0.96 pound)), A. africanus (450 grams [0.99 pound]), and H. habilis (600 grams [1.32 pounds]).

Answer 2

-A. afarensis, A. africanus, H. habilis, H. neanderthalensis

Step-by-step explanation

The development of the brain in hominid species enabled the homids to make and use tools , communicate using sign languages and develop into species that have self-awareness and creativity. This expansion of the brain influenced lifestyle and social structure of these species. The Homo ergaster had a brain capacity of 900 cc, 600 cc for the Homo habilis and 1500 cc for Homo neanderthalensis.
