Scientists are hoping to create Asian elephants that can withstand sub-zero temperatures like mammoths once did in order to help conserve the Arctic.
In other words, the team is hoping to engineer Asian elephants that are able to withstand the freezing temperatures of the Arctic.
"Thousands of years ago...there was mostly grass. Now it's mostly trees," Church said."The Arctic is in need of restoration." In some environments, like the rainforest, trees form a major habitat for many different animal species. But, in the Arctic, Church said that they actually exclude larger animals.
Large herbivores can actually compact this snow, reducing its ability to insulate the ground beneath, thus reducing the risk of soil thaw. Grasslands also reflect more heat and light back into the atmosphere: a thick wooden forest is darker, and will therefore absorb more heat, than a snowy, grassy plain.
"There are a lot of people who feel that [the extinction of mammoths] was greatly exacerbated by predators that stood on two legs and threw spears," Church said."I think that that is quite likely."
