Embryonic development. Historical artwork showing two stages in the embryonic development of a tortoise (left) and a chicken (right). This illustration by Ernst Haeckel incorrectly shows similarities between the embryos,as evidence that all vertebrates (including humans) share a common ancestry (the biogenetic law). In fact,the embryos show greater differences than appear in his diagram,and some of the drawings were deliberately faked to support the theory | |
