Answer 1

Ans1)a. Because whole productive groups were selected instead of individuals, aggressive traits were selected against.

Explaination:selection against aggressive traits in whole productive groups of chicken helps chicken to enable them co exist harmoniously and cooperate in nature.

Ans3)true

Explaination :Adaptations can be the epitome of shortsighted selfishness, even harming everyone over the long run because sometimes these adaptation cause mote harm after a long period of time than their usefulness.

Ans4)c. Homo sapiens and Homo neanderthalensis
