Answer 1

Answer)

Two trends unique to genus Homo are

A) Becoming bipedal: walking through two limbs (usually rear one called as legs) is an evolved form of locomotion and an unique feature of genus Homo. Bipedalism in genus Homo is a significant anatomical change that was possible due to spine anatomical evolution. This had allowed more independent use of fore limbs (hands) for diverse activities.

B) Brains getting larger: Evolution of genus Homo is marked by larger and more complex brain so as to store as well as process more and more information. This had made Genus Homo to be wiser during evolution.

These trends appear related primarily to

C) Reduced predation risk: efficient locomotion reduces predation risk.

D) Tool use: Larger brain helps in processing more complex information and making organism fit for better use of tools.
