LIFE SCIENCE

Detailed explanation-1: -Evolution is a process that results in changes in the genetic material of a population over time. Evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species.

Detailed explanation-2: -Evolutionary loss of traits can occur if traits are selected against or if a trait becomes redundant. This is typically driven by a weakening or removal of the selection pressure maintaining the trait (Maughan et al.

Detailed explanation-3: -Genetic variations can arise from gene variants (also called mutations) or from a normal process in which genetic material is rearranged as a cell is getting ready to divide (known as genetic recombination). Genetic variations that alter gene activity or protein function can introduce different traits in an organism.

Detailed explanation-4: -Evolution Is Change in the Inherited Traits of a Population through Successive Generations. Evolution describes changes in inherited traits of populations through successive generations.
