Detailed explanation-1: -In other words, evolution doesn’t progress in one fixed direction-but it’s not entirely random either. With so many environments selecting for all kinds of traits, evolution has resulted in the countless species that have lived on Earth.

Detailed explanation-2: -According to the theory of evolution, the fittest people are those who have the best environmental adaptations, enabling them to survive and reproduce more successfully than other people. The concept of “survival of the fittest” in evolution, was coined by Charles Darwin to explain the process of natural selection.

Detailed explanation-3: -Charles Darwin (1809-1882) and Alfred Russel Wallace (1823-1913) are jointly credited with coming up with the theory of evolution by natural selection, having co-published on it in 1858. Darwin has generally overshadowed Wallace since the publication of On the Origin of Species in 1859, however.

Detailed explanation-4: -Selection: Survival and Reproduction.
