General:
Archeopteryx: This fossil is exactly NOT an indication how reptiles become birds. It is already a creature able to fly and hence is subject to natural selection in his �habitat�, i.e. will be improved to a better bird. It doesn�t show us what gain a creature without usable forelegs and not able to fly had above birds and hence why wings were invented. We can guess but have no fossil prove for it up to now. Look here:

�On the whole, though, this is still a gappy transition, consisting of a very large-scale series of "cousin" fossils.�
and
�GAP: The exact reptilian ancestor of Archeopteryx, and the first development of feathers, are unknown. Early bird evolution seems to have involved little forest climbers and then little forest fliers, both of which are guaranteed to leave very bad fossil records (little animal + acidic forest soil = no remains). Archeopteryx itself is really about the best we could ask for: several specimens has superb feather impressions, it is clearly related to both reptiles and birds, and it clearly shows that the transition is feasible�. (from http://www.talkorigins.org/faqs/faq-...rt1b.html#bird )

People, not everyone that points out weak spots in the �natural selection� theory is a creationist. I�m not, for all it matters. It just means that there may be other �forces� that drive evolution that we have not yet discovered. Maybe nature likes to jump every now and then with the gene pool and new species evolve. We don�t now. But keep asking and thinking of other possibilities! That�s what science is all about.
