WebDerived traits are those that have changed from the ancestral form and/or function. An example is the foot of a modern horse. Its distant early mammal ancestor had five digits. Most of the bones of these digits have been fused together in horses giving them essentially only one toe with a hoof. WebAn example of homologous characters is the four limbs of tetrapods. Birds, bats, mice, and crocodiles all have four limbs. Sharks and bony fish do not. The ancestor of tetrapods evolved four limbs, and its descendents have inherited that feature — so the presence …

If biological evolution is true then there should be structural and genetic homologies and if such homologies don't exist the theory is false. So looking for such homologies tests evolution and evolution has passed that test.
