In your letter, you need to explain how the theory of evolution is supported by evidence. Be sure to include the 4 pieces of evidence for evolution as well as an example of each.

Answer:

The theory of evolution is supported by several types of evidence. Comparative anatomy shows that different organisms have homologous structures inherited from a common ancestor; for example, the forelimbs of humans, bats, whales, and cats have similar bone patterns even though they perform different functions. Similar embryology shows that related organisms develop in similar ways; for example, vertebrate embryos such as human, chicken, and fish embryos have tails and pharyngeal pouches during early development. Molecular homologies show similarities in DNA and proteins; for example, humans and chimpanzees have very similar DNA sequences, indicating a common ancestor. The fossil record shows that organisms have changed over time and includes transitional forms; for example, Tiktaalik has features of both fish and early four-legged animals, showing the transition from water to land.
