Question: What is evidence of common ancestry? Answer: Evidence of common ancestry is fossil records, homologies, biogeography, and gradualism.

Expand The fossil record, is the accumulation of all fossilized remains that scientists have collected around the world. Homologies are similarities in anatomical structure, gene sequences, developmental stages, or any other criteria that point to a common ancestor. Biogeography is the study of past and present geographical distribution of species. Gradualism is the idea that evolution occurs gradually. Changes or adaptations appear slowly and sequentially over time.

heck Yes/No Way (Choral Responses) The fossil record, is the accumulation of all textbooks in the world. The fossil record, is the accumulation of all fossilized remains that scientists have collected around the world. Fossils can give clues about how organisms changed over time. Scientists study the similarities and differences in bones, shell shapes, or other features over time. A likeness between the bone structure of one creature and that of another may indicate a common ancestor. Continental drift, the breaking apart and movement of continents from one massive landform named “Pangaea," explains why many species evolved into new species.
