Mammoths still roamed the Earth when Egypt's pyramids were being built

A new study has shown that some Ice Age mammals survived much longer than previously thought.
While it is easy to imagine that giant Ice Age mammals such as the woolly mammoth and the woolly rhinoceros died out long before the advent of human civilization, research in recent years has shown that these animals survived much longer than anyone had realized.

Previous studies had indicated that while most mammoths likely died out around 10,000 years ago, a few had managed to survive in small populations on remote islands off the coast of Siberia.

There had even been suggestions that some of these isolated island populations had held on until around 4,000 years ago.

Now though, the results of a ten-year study involving the collection and analysis of 535 samples of sediment and permafrost from Siberia, Canada, Alaska and Scandinavia have yielded evidence to suggest that mammoths had still been roaming the wilds of mainland Siberia as recently as 3,900 years ago.
This means that these animals were still around after the construction of the Great Pyramid of Giza.

The researchers also determined that the woolly rhino had survived until around 9,600 years ago.

The findings involved analyzing traces of animal DNA found preserved in the sediment.

"An individual animal continuously spreads DNA throughout its lifetime in its dung, urine, epidermal cells, and hair, containing millions of DNA segments as it wandered across its full geographic range, but only left one skeleton upon its death, which is far less likely to have been preserved, recovered and dated," said study co-author Yucheng Wang from the University of Cambridge.

"By sequencing only a few of these DNA molecules preserved in the environment, we can identify its existence and range. It is therefore not surprising that sedimentary DNA could produce a later and more accurate extinction estimate."

Well, it did appear to be a mammoth task.

Amazing discovery! As someone fascinated with the idea of relict populations of prehistoric animals surviving longer then usual. This really excites me. Though I don't exactly agree we still didn't play a part in their extinction. These were probably just smaller populations that just managed to thrive much longer.
