Genetic Evolution
Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how gene…

Explain into details the concept of speciation .

Expert Solution

Introduction :

Evolution is the end result of a number of factors working together. It is said to occur when new species form via speciation. It occurs through accumulation of genetic variation in a populations alleles and genotype from generation to generation. Thus, its the population that evolves and not its individual members.
