Simple example:
There is a species of frog that shoots poison darts. In order for this to happen, the frog needs 1) poison glands, 2) darts, 3) muscles and nerves that can shoot the dart, 4) brain physiology that can target prey and trigger the attack, and 5) probably a bunch more stuff too. None of these attributes seems to have any evolutionary advantage without the others so how does the theory of evolution/selective generation explain that something like the poison dart shooting mechanism developed slowly from generation to generation?
I'm generally a scientific guy and not overly religious, but the "theory of evolution" never passed my common sense test. I can believe that species adapt to their environment, but I can believe that complex biological mechanisms like the one listed above can gradually develop over many generations.
Thoughts? ( no religious rants or long Bible quotes please)
