Interesting Finds

Just want to get a heads up out here in cyberspace. I've been busy with various things - all progressing well enough. Got some serious organizing started - though with still much work to do. But at least I've been in a cleaning and organizing mood all week. That isn't to say I've completely forgotten my self-appointed challenge for these days - the rough draft of my Pleistocene project. I did get a bit of the preliminary reading started - and with some really great and possibly evidence-boosting effects. Granted, this is merely preliminary readings - but they can and often do give me some interesting directions and avenues to follow. For instance, it looks like population increases - significantly large ones might just be the norm following glacial retreats. It turns out that the Cambrian Explosion was preceded by a massive Ice Age - resulting in a veritable Snowball Earth - when all but the equatorial regions was covered by massive ice sheets. This is quite informative and very helpful - though it seems to be a controversial issue - though why that is the case remains to be seen. Also, lighter isotopes in rock and ice cores indicate mass extinctions. This information, too is very helpful. We should be able to track if and when mass extinctions - especially global scale ones - took place with respect to various ice ages - especially at the end or melt-off stages. Also, an interesting bit of information may show that we humans may have stopped the glacial/interglacial cycles - or at least seriously slowed them down - with global warming. I guess it's something we have yet to see.
