Human Evolution

About 10,000 B.C. the last Ice Age ended. As the planet began to warm man began developing agriculture and complex human societies.

Twelve thousand years ago was just a blink of the eye. I have been in wonderful gigantic domed buildings which were built 2,000 years ago. At about the same time they had metal hot water heaters and a bronze two stage pump which was used to de-water mines. The sewer lines were large enough to stand up in, and the fresh water supply was piped in from as far as 50 miles away.

This super rapid development is amazing when you think about it…
