Please explain why you think that embryos showing differences at this stage of their development is evidence against evolution and for design. Embryos begin to develop in remarkable similar ways, so please show why arbitrarily picking a point in their development and saying "you can tell the species apart now, so they must have been designed" is evidence for your position.

I'm not inclined to keep talking on this thread because none of us here knows much about this subject, though that doesn't stop certain people from making ignorant criticisms all the same. What we would need to do is learn some real things about embryology so that we could discuss it intelligently, but I can't say it's near the top of the list of my own priorities.
