Answer: Karl Von Baer was an Estonian biologist and generalized the observations around embryology into laws bearing its name.
His laws indicate that the earlier we are in the embryonic phase, the closer the classes of distant organisms look to each other. As embryos develop, they diverge further from embryos of other species.
The von Baer sequence poses more problems for evolutionary mythology since natural selection cannot explain the pattern of embryonic development. Natural selection does not want to know if a trait is widespread or specific. It does not see attributes so it cannot sort them according to a special sequence.
