It's something that can be tested and measured out in the real world. I was really quite surprised to hear two ideas in particular. One was that evolutionists when we are amongst ourselves say that there's not very much about it. I am one of those evolutionists. One is speciation because it is something that is tested and measured in spite of what you've heard said earlier, and the other is natural selection.
Natural selection is the much easier of the two to test and measure on here.
One of the other things is just an aside that I heard was an implication that somehow evolution is bad for the morals of your kids. I've got my tie tack on for my youngest son who is an Eagle scout and became one in December. I don't think that his morals have been somehow degraded by having an evolutionist for a father that's been raising him and taking care of him. We could spend quite a bit of time, but I can't do it in five minutes, obviously, talking about how scientists measure speciation, natural selection, and so on like that. There are bookshelves in OU's library that are filled with books and journals on how this is done.
