The woolly mammoth was a very large elephant-like mammal that lived on Earth several thousand years ago.   Some mammoths grew to be four meters high  and the largest weighed almost nine tons.   Both male and female mammoths had very large tusks  and walked on every continent  except Australia and South America.   Sadly, these giant creatures became extinct. The last mammoths lived as recently as 4,000 years ago  and their well-preserved bodies  can be found frozen in the tundra of Siberia.   Because their bodies were so well protected  from decay in the permafrost,  their genetic material remained intact.   Scientists at Harvard University are researching ways  to bring the mammoth back to life.  According to these researchers,  it is possible to program the Asian elephants’ genes  with a mammoth’s genetic material.  This is can be done  because of a recent scientific developments in gene editing using a new tool called Crispr.  Crispr allows scientists to cut out specific genes  and replace them with different ones.  They estimate that we will see a living mammoth in less than 10 years.
