> Which prehistoric animal was still living when the Great Pyramids were beingbuilt?And the answer: woolly mammoths. When construction of the Great Pyramids began about 4,500 years ago, a smallpopulation of woolly mammoths still existed on a small island off the coast ofSiberia. Numbering between 500 and 1,000, this small group of mammoths continuedto live until about 1650 B.C.Woolly mammoths were the last in a long line of mammoth species, rising inprominence as far back as 2 million years ago. Their appearance and size areamong some of the most well-studied of the prehistoric species, as skeletons andwhole frozen carcasses of the beasts have been found in Siberia and Alaska.Their depictions appear in many prehistoric cave paintings, and have long beenstudied in Asia and Europe.Frozen woolly mammoths were excavated by Europeans as early as 1728. Up untilthat point, scientists and archaeologists knew the mammoth was an ancestor ofthe elephant, but had little conceptual knowledge of its actual physiology.Their fur, tusks, bones, and even some internal organs were preserved in theice. The earliest excavated mammoth even still had grass between his teeth!Finding soft tissue of these extinct creatures has led scientists to believethat the species could be recreated by scientific means. A 2015 genome projectsupported these findings, but ultimately lacked feasibility.What do you think? Should these giant creatures return to the Earth?
