Evolution, religion, and ignorance.

[John V]

Well then you would need to propose a mechanism by which those smaller changes are prevented from accumulating. Until then, the logical view is that small, demonstrable changes will build up, just as it's logical to consider that if I walk solidly in one direction without interruption, I will eventually have walked a mile.

First, you haven't proven that the small changes represent anything new.

By the first definition, which I accept, a simple example of evolution would be that one generation has 75% brown eye genes and 25% blue eye genes, but the next generation has 74% brown eye genes and 26% blue eye genes. There is nothing new in this form of evolution, and nothing to accumulate.

Second, you haven't proven that changes go solidly in one direction. Going back to my example, the third generation could have 75% brown eye genes and 25% blue eye genes. This would be evolution from the second generation, but it would have gone nowhere from the first generation.
