Answer 1

Ans. -

Random changes then created a depression in the light-sensitive patch, a deepening pit that made "vision" a little sharper. ... Eventually, the light-sensitive spot evolved into a retina, the layer of cells and pigment at the back of the human eye. Over time a lens formed at the front of the eye.

Five different forces have influenced human evolution: natural selection, random genetic drift, mutation, population mating structure, and culture.

Evolution Examples in Nature. Peppered moth - This moth had a light coloring darkened after the Industrial Revolution, due to the pollution of the time. This mutation came about because the light colored moths were seen by birds more readily, so with natural selection, the dark colored moths survived to reproduce.
