If an organism develops a structure (or loses one), it didn't do so for no reason; a selection pressure caused it to evolve that way. So a vestigial organ is just the loss of that organ, which is just an important evolutionary transition as gaining an organ so I wouldn't call it a blunder. Well, actually... The reason the laryngeal nerve evolved as it did was because it was so much simpler to just add a bit to the length each time, instead of rerouting the entire thing. So there is a reason why its like that, even in giraffe's. (17-03-2011 09:22 PM)karlt10 Wrote: We have gills in the embryo stage..... Thats a good one.

Well i don't mean that evolution does things for no reason, Dae, but more that not every change brought about by evolution is beneficial to survival and well constructed
edit: By beneficial to survival, i mean, not optimally. |

Natural selection and survival of the fittest are the driving forces that create changes. Evolution is the changes that result from the those driving forces. This process has no forsight. Many creatures have evolved into specialists for one particular environment, and then went extinct because they could not survive environmental changes. When I find myself in times of trouble, Richard Dawkins comes to me, speaking words of reason, now I see, now I see. |

A phonetics professor of mine pointed out the blunder of our air passageway crossing our food passageway, resulting in sometimes fatal choking. Was the "Great Designer" trying to enforce silence at mealtimes? |

How about the rabbit in general? The intestines precede the stomach in the rabbit. This means that wild rabbits, important to note because tame rabbits are fed preprocessed pellets, have to eat their food twice. You heard that correctly. In order to obtain any nutritional value from their food they have to digest it twice by consuming their fecal material. They are smart enough to not eat the poop of their poop but how about that for a blunder! I believe this is an example that Stephen Jay Gould gave when he was asked to think of an unintelligent design. Don't quote me on that.
