Did the ancestors of modern horses have fewer toes or more toes than horses today?
The embryos of most vertebrates (animals with a backbone) are very similar early in development.
populations of living things changing over time
all of these
organisms that can breed and produce fertile offspring
They are homologous structures because the bone structure is similar and comes from a common ancestor (forelimbs).
