Detailed explanation-1: -Darwin defined evolution as “descent with modification, ‘’ the idea that species change over time, give rise to new species, and share a common ancestor. The mechanism that Darwin proposed for evolution is natural selection.
Detailed explanation-2: -Part of the Darwin exhibition. Overwhelming evidence shows us that all species are related–that is, that they are all descended from a common ancestor. More than 150 years ago, Darwin saw evidence of these relationships in striking anatomical similarities between diverse species, both living and extinct.
Detailed explanation-3: -Common descent is an effect of speciation, in which multiple species derive from a single ancestral population. The more recent the ancestral population two species have in common, the more closely are they related.
