Most of the bones of these digits have been fused together in horses giving them essentially only one toe with a hoof. WebIn the light of this, homologies are relevant to judging whether you should adopt evolution or intelligent design. 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.
