When you say related species......do you mean that all mammals go through similar stages; all birds go through similar stages; all insects go through similar stages and so on......no matter whether the insect is a tarantula or a lady bug Mammals will go through more similar stages than say humans & birds. This is because all mammals share more common development than mammals & birds. But mammals, birds & reptiles share a lot of more basic (read ancient) common development, so the earliest stages of how a body plan starts to develop will be similar. If you go all the way back to very primitive small worm like organisms, most all living "animals" are all bilaterans, that is animals that have bilateral symmetry. The genetic mechanisms for laying this down in all modern species is similar, hence the early embryo development reflects this. At a somewhat later stage, the gill structure of fish, and parts of our face & neck develop from a common portion of the embyro that looks rather like gills in all embryos. So on it goes... Thanks for the quick tutorial. <g> It was really helpful. As I said previously, life itself and how it works as a part of the evolutionary theory is such a miracle, I have to wonder why the fundamentalists are so unwilling to endorse it as something coming from their deity. ted
