PLEASE HELP! ASAP! FIFTEEN POINTS!
oee [108]

Answer:

Anatomy supports the theory of evolution because some species share similar physical features that was present in a common ancestor.

An example of shared anatomy is sharks and dolphins. types of analogous structures, such as dolphins and sharks, do not prove species are related, but rather they support the Theory of Evolution by show how species do build up adaptations in order to fit into their environments

Molecular biology because DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.

in recent research is has been shown that the myoglobin and hemoglobin sequences for dozens of mammals, birds, reptiles, amphibians, fish, worms, and molluscs were related.

Structural similarities is when different animals share the same structural similarities. For example the skeletons of turtles, horses, humans, birds, and bats are very similar, despite their t different ways of life and the diversity of their environments.
