And?
You do know that your opinions on the state of the environment has absolutely zero bearing on the lampreys ability to survive said environment with the need to adapt to it, right?
The environmental factors, even during extinction events were obviously stable enough for some species of lamprey to survive and proliferate into modern times.
Part of the flawed thinking is that extinction events are total extinction and that isn't the case. If it were, we wouldn't even be here.
Whatever causes those events has not altered the environment on a large enough scale to drive the extinction of all species. In fact, extinction events would empty previously occupied niches that can be exploited and allow for more rapid bursts of evolution in whatever groups are exploiting them.
Or is this yet another fact you will ignore/dismiss?
I'm finding that with certain people claiming they are Christian, ignore and dismiss seems to be a big part of their SOP.
They don't like to answer tough questions and will jump through all sorts of hoops to avoid answering them.
Personally, that doesn't seem all that Christian to me. In my opinion, it renders certain positions and tactics hypocritical.
You are correct. The claims that the existence of modern species of lampreys refute evolution are mistaken. The evidence shows that whatever altered the environment on different occasions leading to mass extinctions did not destabilize the global environment enough to end all life, including lampreys.
It is just wishful thinking coupled with bad assumptions and ignorance to come to a desired conclusion that is easily refuted.
