I’ve heard a lot of theories about the development of human beings, including the theory that we can thank Mother Nature for our bodies, as well as Father God for our souls (and bodies, too); but being the totally unscientific person that I am, I had never heard before that modern humans may owe their existence, in part, to a climate change:
"Climate change in Africa gave rise to modern humans.

"Climate change in Africa prodded mankind’s distant ancestors along their evolutionary path as forests gave way to grasslands, forcing early humans into an open environment where it appears stone tools and long strides first developed.
"But while most past changes in weather patterns were gradual — giving our pre-historic ancestors a chance to adapt — the pace of global warming today could overwhelm modern Africa.
"The United Nations projects that temperatures may rise by 1.4-5.8 Celsius by the year 2100."
Great. Another global warming scare story.
You’d not heard of that? Really? Wow. Sneaky of G-d to dry up East Africa 4 million years ago, just to get us on our feet (so to speak).
On the other hand, if the climate cools off, can we go back up the trees?
