Question

1. evolution is:

a. fixed in one direction
b. completely random
c. neither entirely fixed nor entirely random

Explanation:

Evolution is a complex process. It is not fixed in one direction as environmental changes and various factors can influence it. Also, it is not completely random as natural selection acts on variations. Natural selection favors traits that are beneficial for survival and reproduction, so there is a non - random aspect. But mutations (which provide the raw material for evolution) have a random component. So evolution is neither entirely fixed nor entirely random.

Answer:

c. Neither entirely fixed nor entirely random
