NEET BIOLOGY

Detailed explanation-1: -Individual organisms don’t evolve. Populations evolve. Because individuals in a population vary, some in the population are better able to survive and reproduce given a particular set of environmental conditions.

Detailed explanation-2: -Individual organisms do not evolve, they retain the same genes throughout their life. When a population is evolving, the ratio of different genetic types is changing–each individual organism within a population does not change.

Detailed explanation-3: -Evolution, in this context, is both a fact and a theory. It is an incontrovertible fact that organisms have changed, or evolved, during the history of life on Earth. And biologists have identified and investigated mechanisms that can explain the major patterns of change.

Detailed explanation-4: -The given statement is True. The evolution does not stop in an organism, and it continues to evolve throughout its lifetime. Every population of species undergoes some sort of evolution, and it varies from one species to another.

Detailed explanation-5: -Because these individuals can share genes and pass on combinations of genes to the next generation, the collection of these genes is called a gene pool. The process of evolution occurs only in populations and not in individuals.
