• Morphological and Anatomical Evidence...  
Embryology provides evidence for evolution since the embryonic forms of divergent groups are extremely similar.
Homologous structures in embryonic development suggest that ancestral structure was maintained as things diversified.

Examples found in comparative anatomy include the forelimbs of humans and the flippers of a whale, which supports the idea of common descent. Although a human arm and bat wing look different, the process of embryonic development is similar.
