@brutamerica: Colossal Biosciences has engineered the mouse equivalent of woolly mammoth genes into these mice, making the world’s first woolly mice. The company is on a quest for species de-extinction and preservation. They birthed 38 mice, all of which were happy and healthy without complications - the only unintended consequence was that they were much more adorable than expected. #science #mice #woollymice #woollymammoth #mammoth #species #extinction #preservation #genes #lab #scientists
