Some people do not appreciate the way I ask questions so help me out here. I would like to know what specific species was the immediate predecessor of the Equidae and bovine species and what specific species evolved from them so how should this question be phrased?
Using the definition of species as - "A group of organisms having many characteristics in common and ranking below a genus. Organisms that reproduce sexually and belong to the same species interbreed and produce fertile offspring."
