Question

explain the Darwin's theory of evolution natural selection with example?

Answer 1

A species is a group of similar organisms that can interbreed with each other to make healthy, fertile offspring. ... Darwin also suggested a mechanism for evolution: natural selection, in which heritable traits that help organisms survive and reproduce become more common in a population over time.

Answer 2

Answer :

i. Darwin’s theory of Natural selection in evolution states that only the fittest organism will be able to thrive in the world. Thus, the organism with useful traits will survive.

ii. The natural selection over-abundance of offspring leads to a constant struggle for their survival in any population. Individuals with variations that help them to survive and reproduce tend to live longer and have more offspring’s than organisms with less useful features.

iii. The offspring of survivors inherit the useful variations and the same process happens with every new generation until the variation becomes a common feature. As the environment changes, the organism within the environment adapt and changes to the new living conditions. Over a long period of time, each species of organism can accumulate so many changes that it becomes a new species, similar to but distinctly different from the original species. All species on the earth arise in this way.

Evolution is a slow and continuous process.
