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: -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.

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: -Charles Darwin was a British naturalist who proposed the theory of biological evolution by natural selection. Darwin defined evolution as “descent with modification, ” the idea that species change over time, give rise to new species, and share a common ancestor.
