POPSHumanity Was Genetically Divided For 100,000 Years the study provides insight into the early demographic history of human populations before they moved out of Africa. “These early human populations were small and isolated from each other for many tens of thousands of years,” says Rosset. MtDNA, inherited down the maternal line, was used in 1987 to discover the age of the famous “Mitochondrial Eve,” the most recent common female ancestor of everyone alive today. This work has since been extended to show unequivocally that “Mitochondrial Eve” was an African woman who lived sometime during the past 200,000 years.

POPSPyramids packed with fossil shells. They say that seashells prove that the rock was quarried, instead of cast in moulds. I can't imagine how making their own 10 tonne bricks in moulds would have made things any easier. Maybe just adding another stage to a process that was already a huge undertaking. I also heard once that after something is build it hasto 'settle' into into it's foundations, Very few builders or architects have been able to find a way to overcome this, but with their weight, and perfect seams with no mortar, the pyramids have only settled a fraction - perhaps a few inches, over thousands of years. Something that seems much more likely with solid rock than bricks. If only the library in Alexandria hadn't burned down with all of the blueprints.
