What support evidence for evolution is provided by comparative embryology?

Answer 1

The embryonic stage for many animals is very similar. For example, fish, bird, rabbit, and human embryos are similar in appearance in the early stages. They all have gill slits, a two-chambered heart, and a tail with muscles to move it. Later on, as the embryos grow and develop, they become less and less similar.

I don't claim expertise in evolutionary theory, but it seems so persuasive that I am willing to accept it as the best concept yet.

I've heard a Creationist say. "Well. there's no example of an animal that is half cat and half dog"

But that just shows that he has no concept of evolutionary theory

Answer 2

The famous saying was that ontology recapitulates phylogeny. It turns out that this is not the case. There are, however, remarkable similarities amongst the vertebrate embryos. There are also numerous connections between ontology and phylogeny, and your question concerns those connections.

Related species have similar embryos

Answer 3

Answer

Embryology does not provide any evidence for evolution. Ernst Haeckel's comparative embryo drawings have been known to be fraudulent for over 60 years although they are still used in some textbooks and by some ardent evolutionists. Embryos are different all through their development. Use of such alleged evidence is at best misleading and at worst is downright deceitful.

Recent attempts to resurrect Haeckel's reputation only serve to show more details of his deceit. One example is how Haeckel deliberately left out the developing "heart pouch" from his drawings of the human embryo.

Second answer

Comparative embryology shows that many different lifeforms go through similar stages of development, which points to common origins. You can read more about this online. Regarding the aforementioned fraud, Robert J. Richards, Professor of the History of Science and Medicine at the University of Chicago, states that the claims are "logically mischievous, historically naive, and founded on highly misleading Photography." For more, see his paper "Haeckel's embryos: fraud not proven."

The Hox genes regulate body plans in embryological development, and are considered one of the primary pieces of evidence for common ancestry of species. Please also refer to the link from Christ's College on the Hox genes for that.

Answer 4

When embryos are in their early stages, they're all really similar and it suggests that every organism has a common ancestor due to their similar embryos.

Answer 5

Your can see similar structures in embryos of different organisms.
