Explanation:
Detailed explanation-1: -Evidence for evolution: anatomy, molecular biology, biogeography, fossils, & direct observation.
Detailed explanation-2: -Fossils, anatomy, embryos, and DNA sequences provide corroborative lines of evidence about common ancestry, with more closely related organisms having more characteristics in common.
Detailed explanation-3: -There are four principles at work in evolution-variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection.
Detailed explanation-4: -Darwin used multiple lines of evidence to support his theory of evolution by natural selection–fossil evidence, biogeographical evidence, and anatomical evidence.
