Everybody remembers the mammoths from the movie ‘Ice Age’. The extinct elephant-like giants with their signature tuskers are easily recognisable with their golden furs and giant bodies. The giants, however, are making a comeback through small mice in a US laboratory, as per reports.

Scientists at the Dallas-based Colossal Laboratories and Biosciences proudly presented mice with typical mammoth characteristics of a mammoth, such as long brown fur, and their accelerated metabolism.

This was, according to reports, achieved through gene editing at the Colossal. However, as per the firm, the ‘de-extinction’ of mammoth, as they call it, will be possible by 2028.

The company CEO in a statement reportedly said that this is a ‘watershed moment’ in their ‘de-extinction mission’.

However, he clarified to a media house that it does not bring the firm any closer to a mammoth, but validates the company’s work towards de-extinction.

As per reports, the scientists took seven genes of mammoth DNA believed to be responsible for their furry coat and its colour, and created multiple mice embryos in surrogate wombs, which produced 38 such golden, furry mice with mammoth’s fat metabolism.

In the future, the company plans to bring back the dodo bird and Tasmanian Tiger next, noted the Chief Science Officer Beth Shapiro, as per reports.

The company, reportedly, has pointed out that 50% of the Earth’s species will go extinct by 2050, mostly due to climate change.

The traditional approach of conservation should co-exist, but what Colossal does is to increase the tools at its disposal to help these species survive, noted Shapiro reportedly.
