Evidence for evolution comes from them. A lot of hard evidence. Archaeology tells us about the kinds of organisms that have lived on the earth all the way back to the earliest fossil, and geology helps us to date those organisms and to learn more about the conditions in which they lived and died. These fields obviously encompass much more but these are some of their major contributions to evolutionary theory.

And one of the major ways we date things in geology is by looking at radioactive decay. I explained in another thread how Henry Morris' claims about radiometric and isochron dating being useless, are flawed. If you have fresh evidence about how they are flawed then you are welcome to present it.



You're almost there with this I think SoSick; it's one of the most sensible things I've read from you. Yes evolutionary theory is informed by biology and genetics, but in all science there is a flow of information back and forth. No scientific field stands in isolation without being aware of what other fields have been discovering. That's one way our whole body of knowledge moves forward.
