Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.Different characteristics tend to exist within any given population as a result of mutation, genetic recombination and other sources of genetic variation.
Evolution – The science of evolution: The central argument of Darwin’s theory of evolution starts with the existence of hereditary variation. Experience with animal and plant breeding had demonstrated to Darwin that variations can be developed that are “useful to man.” So, he reasoned, variations must occur in nature that are favourable or useful in some way to the organism itself in the.
11 days ago · "Species" is not very well defined, but if these new birds could have bred with the old ones, they’d probably also be able to breed with the common ancestor, which would make them all the same species and would mean they never died out at all.
