The company behind the ambitious target is Colossal Biosciences, and it’s their goal to have living, breathing mammoths at their Texas-based facility by 2028.
“Colossal Biosciences is, to our knowledge at least, the world’s first de-extinction and species preservation company,” founder Ben Lamm told IFLScience during an interview about whether or not we can bring back dinosaurs. “What that means to us is looking at and understanding which genes are associated with the core phenotypes, or physical attributes, that existed in an extinct animal.”
“For example, for the woolly mammoth, it’s the dome cranium, the curved tusk, and whatever is making it cold-tolerant, as well as a lot of things under the hood. Things like how nerve endings respond to freezing temperatures, how the body produces haemoglobin, and the shaggy wool coat.”
Finding those genes means first looking at an extinct animal’s closest living relative, and in the case of the mammoth, that’s the Asian elephant, which is 99.6 percent the same, genetically speaking.
“What we’re asking is how can we at Colossal understand the core genes that made elephants cold tolerant,” Lamm continued. “Those genes are now extinct, so how do we de-extinct those genes and put them into the architecture, if you will, of an existing living animal?”
