Evolution is "the change in the inherited traits of a population from generation to generation" (http://en.wikipedia.org/wiki/Evolution). How does evolution account for the earliest functioning reproductive system? It could not have been the result of evolution, for this would entail a previous generation and it would no longer be the first reproductive system. It would have had to be the result of a non-evolutionary process. But that a non-evolutionary process would produce a reproductive, evolving, organism seems odd.

I am an atheist, so please no insults about religious dogma. I completely ignorant of evolution but I feel my question is still a valid one.

I live in Naperville, Illinois and I brought two caterpillars from Minnesota. They are kept in a jar, and I feed them milkweed leaves, which I brought from Minniapolis. However, I can't find milkweed anywhere near my house, nor can I find them in stores. The caterpillars only eat milkweed, and look like caterpillars with black, white, and yellow stripes. They have 2 short, black antennae things on their front and back end.

1. Can anyone tell me what species these caterpillars are, or what kind of butterfly they will become (no scientific names please)

2. Can anyone tell me which stores/where I can find milkweed plants or seeds in Naperville, Illinois?

Thank you. You'll be saving two bugs!
