Which of the following is evidence of evolution?

Explanation

All three options provide strong evidence that species evolved from common ancestors. Fossils show how organisms changed over millions of years. Similar embryo development suggests different species share common origins. Homologous structures like arm bones in humans and whale flippers show evolutionary relationships.

Each type of evidence supports evolution from a different angle. Fossils give us a timeline of changes. Embryos reveal hidden connections between species. Similar bone structures show how different animals adapted the same basic body plan.

Scientists use multiple lines of evidence together to build a complete picture of evolution. No single piece of evidence proves evolution alone. The combination of fossils, embryology, anatomy, and DNA all point to the same conclusion about common descent.
