Climate change: sudden cooling (Introduction)
dhw: I know this is going over old ground, but so many of these interesting findings that you alert us to point firmly at the randomness with which life forms evolve, appear and disappear. Since climate change is unpredictable, and brings with it large scale extinctions and/or remarkable innovations (which themselves disappear in the next round of climate changes), I don't see how one can with any confidence extrapolate a plan, unless the plan is simply "que sera sera".-We know of six mass extinctions and amazing swings in climate. Yet life continued an evolution from simple to complex. The only conclusion that is safe is that living forms are extremely resilient, based on a very complex biochemistry that current science continues to illustrate. > > dhw: The other obvious conclusion one has to draw ........... they must have developed out of existing organisms, presumably in response to changes in the environment. ...... What part of those existing organisms do you think would have been responsible for devising the new structures? Or do you think your God preprogrammed the Ediacaran tubes to appear and then disappear as they did?-All I can do is look at current evidence. When the Burgess shale in Canada was the only place to look at the Cambrian Explosion, Darwinists could plead lack of evidence. But now that Chinese areas and Australian areas have opened up the Cambrian and its past aged layers with no change in the preceding Edicaran, the evidence for the unexplained explosion is extremely strong. We have no way of knowing whether God stepped in and fiddled directly or as I think is more possible is that original life is so complex and and potentially inventive that the huge jump in complexity simply waited until the climate had enough oxygen to fuel the more complex organisms, and then proceeded to produce them.
