- Which of the following is not a statement of von Baer's laws? Less general characters develop from the more general, until finally the most specialized appear. The general features of a large group of animals appear earlier in development than do the specialized features of a smaller group. (C) All of the above are Statements of von Baer's laws. The early embryo of a higher animal is never like a lower animal, but only like its early embryo. The embryo of a given species, instead of passing through the adult stages of lower animals, departs more and more from them.Why do scientists consider vestigial structures (like a human appendix) evidence for evolution?If natural selection can only operate on existing variants, where does all that variation come from? If, as Darwin (1868) and Huxley concluded, variation arose from changes in development, then how could the development of an embryo change when development is so finely tuned and complex?

The general features of a large group of animals appear earlier in development than do the specialized features of a smaller group. C) All of the above are Statements of von Baer's laws. D The early embryo of a higher animal is never like a lower animal, but only like its early embryo. E) The embryo of a given species, instead of passing through the adult stages of lower animals, departs more and more from them.What is Biogenetic law?
