Rebirth of the mammoth?

The mammoth became extinct about 4000 years ago. The size of mammoths varied from species to species, but on average they reached 2.8 to 3.7m shoulder height, corresponding to today's elephants.

Since 2008 the genetic information of mammoths has been decoded by about 70 %. Thus it is known that they are more closely related to the Asian than to the African elephants. Now scientists want to clone mammoths again, to be exact, the best known species of woolly mammoths. To do this, the genetic material of a mammoth must be implanted in an Asian elephant so that the Asian elephant cow (female elephant) can carry the mammoth clone. However, the Asian elephant is already on the red list of endangered species and is listed as very endangered. The population of the Asian elephant has declined in the last 60 - 75 years by 50%. Therefore, the recloning attempt will not be started until the Asian elephant is back off the Red List of endangered species.

However, the habitat of mammoths is no longer the same as it used to be, there are cold regions on earth but they are cold and humid, they are not used to mammoths, they are used to dry cold steppe habitat. This could lead to problems...
