New Delhi, April 9 -- On Monday, Colossal Biosciences, a genetic engineering startup, showcased an unlikely cub to the world-the dire wolf. The species, once found commonly across the Americas, had been extinct for over 10,000 years. Is human immortality also around the corner?

How did the extinct dire wolf return?

Scientists at Colossal used genetic reconstruction to recreate the long-extinct species-made popular by the HBO hit show, Game of Thrones. Scientists extracted genome data of excavated dire wolf fossils, and used it to rewrite the genomic sequence of the common wolf, or Canis lupus. It then used this gene sequence and to reproduce the dire wolf cubs-with a variety of domesticated dog species serving as the mother. Using AI as...
