How a distinct larval form emerged is certainly an interesting question; here's what I think is a reasonable possibility:
The earlier and more primitive insects have immature phases that are much like their full-grown one, and that usually share the same habitats. But these immature phases can suffer selection different from that of the mature phases, because they do not fly or try to reproduce. Thus, immature and mature phases can diverge in features. One problem with how much of such evolution can happen is that a growing insect has to change from an immature configuration to a mature configuration. However, as they grow, insects molt, and an insect can extend its final molt so that it can do whatever configuration changes are necessary. And with a sufficiently-extended final molt, the immature and mature phases can look considerably different and be adapted to very different lifestyles -- thus a 4-stage lifecycle. |

The explanation in terms of atoms and molecules for a great deal of what you see around you everyday is a mystery. I don't see you attacking atomic theory. The argument you are using is also a "moveable goalpost" arguement. If we had provided you a detailed plausible hypothesis of how the life cycle of lepidoptera evolved, you would then simply picked some other question. If we answered that one, you would then try another. Like all sciences, biology has many mysteries. Indeed if all the mysteries are solved, biologist will have to find another profession. |

We admit that there is no more evidence to evolution as there is for creation in regards to butterflies. And btw - this is how evolutionists argue with creationists and vice/versa. It's called debate. [ April 05, 2002: Message edited by: unworthyone ]</p> |
