Question

Explain whether human evolution is adaptive radiation or not?

Answer 1

Hint: Evolution is defined as the process in which species evolve in millions or billions of years. The process of evolution relies on the process of natural selection. J.B.S gave the theory of the origin of life. Haldane, in 1929. He stated that life originates from simple inorganic molecules. Then these inorganic molecules change into organic molecules in millions of years.

Complete answer:
The father of evolution was Charles Darwin. The main contribution of Charles Darwin of evolution was that he explained the mechanism that represents evolution. This term is known as natural selection. Natural selection is based on the adaptation of a species in the changing environmental condition where a species can survive and reproduce better than others.

Human evolution is not adaptive radiation. This is because adaptive radiation is described as the diversification of ancestral lines into different forms. This will produce a diverse ecological niche and is a quick process.

On the contrary, human evolution is a slow process and is different from adaptive radiation. Therefore, the human revolution can not be called adaptive radiation.

Additional information:
The analogous structures are similar in function and structure, but they have different origins. For example, the wings of birds and bats have a common function, and that is flying.
The structures that are similar in structure but differ in their functions are known as homologous organs. For example, the forelimbs of frog, man, and the whale's flippers are known as homologous organs.

Note: Charles Robert Darwin gave the theory of evolution in 1859. He described that evolution is a process through which organisms change due to physical or behavioral traits. Reproduction and variation are the key components of natural selection. The organism that favors the favorable traits is more likely to reproduce. Therefore, these organisms can pass these traits to the next generation easily.
