NEET BIOLOGY

Detailed explanation-1: -The idea of natural selection is that traits that can be passed down allow organisms to adapt to the environment better than other organisms of the same species.

Detailed explanation-2: -Evolutionary adaptation, or simply adaptation, is the adjustment of organisms to their environment in order to improve their chances at survival in that environment.

Detailed explanation-3: -Adaptations are inheritable characteristics that increase an organism’s ability to survive and reproduce in an environment. Adaptations can help an organism find food and water, protect itself, or manage in extreme environments.

Detailed explanation-4: -Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).

Detailed explanation-5: -Compared with new mutations, adaptation from standing genetic variation is likely to lead to faster evolution, the fixation of more alleles of small effect and the spread of more recessive alleles.
