<<I believe in evolution, but the increase in stature isn't due to evolution, it's due to
nutrition. That one I am sure about.>>

I think this is a little more complicated than you are making it. Once men were powerful and clever enough to hunt successfully, they rapidly got taller and brighter because of increased nutrition. However, prior to that point there are certainly lots of examples in the fossil record of intermediate "missing link" beings who were on an evolutionary path. The four-year-old boy who was found recently would certainly be an example of that. Does anyone have that link? It was in the news, but I cannot find it at the moment.

Blue, don't be so sure about height. As I recall (and I am hazy on this one), the average stature of adult male Egyptian mummies was around 5'. But even if you are correct, many other examples abound.

Evoution does not require speciation -- simply changes that get fixed in the gene pool. The most striking example is industrial melanization in moths in England. By the way, this is the example that is generally used as proof of natural selection.

CB, That's all that different species are, variations on a fundamental theme. Are a horse, an elephant, and a mouse really that different? The differences are body size and shape, and the sizes of appendages and hair, etc. They are different species only because of the great amount of time since they branched off from their common ancestors made their DNA and mating possibilities too different.
