I'm not sure. I haven't looked into it. Looks like a case of microevolution at work to me.
What does? What on earth are you talking about?
Yes, that's what we usually see with YEC. The further you go, the less you know. Kind of the opposite of science. Science knows things that YEC doesn't.
So I hope you see how our "kind" notion is utterly useless? Here is one of the largest number of species, and you can't tell us whether it consists of a single kind or 450,000 kinds.
Well, let's do it either way.
If you say it's a single kind, then we should have seen at least a million new species of beetles come into existence in the last 6000 years, with at least half of those going extinct. So that would be around 166 new species of beetles every year. Let's take the last 100 years, when we've really been looking. Have we seen almost 2000 new species of beetles come into existence in the last 100 years?
If you say it's 450,000 kinds, then what you're saying is that Noah took almost a million beetles on the ark. I haven't gotten into ants, spiders, and so forth. Just beetles. A million of them.
As you see, math is a great help to science. It enables us to falsify hypotheses. Like yours.
ToE predicts that speciation events will be rare and slow, and would take a few hundred million years to produce the many species of beetles we have today. And lo, that is exactly what we have. Another data point to support the theory.
