Evolution
Anatomical evidence of evolutionevidence of evolutionA large body of molecular evidence supports a variety of mechanisms for large evolutionary changes, including: genome and gene duplication, which facilitates rapid evolution by providing substantial quantities of genetic material under weak or no selective constraints; horizontal gene transfer, the process of Evidence_of_common_descentEvidence of common descent - focuses on similarities and differences in the body structures of different species. Comparative anatomy is the field of study dedicated to this. Similarities in anatomical structures of different species signify that the two species have a relatively recent common ancestor.
