Dear MEL Topic Readers,
Scientists say they have resurrected the dire wolf
A US biotech company announced that it has brought back an extinct dire wolf that last walked the Earth about 10,000 years ago. Its scientists extracted DNA from an old tooth and skull, assembled two complete sets of genetic information, and compared the genomes with those of living wolves, jackals, and foxes to identify the genetic variants, which were found to be 99.5% the same as gray wolves. Then, they altered gray wolf cells, cloned cell lines, and transferred them into donor eggs from large mixed-breed hound dogs that acted as surrogate mothers. A video shows three resurrected dire wolves running around in a fenced area like dogs. The company has also been working on resurrecting the mammoth, dodo, and Tasmanian tiger since 2021. Also, such bioengineering technologies might help conserve critically endangered animals. Will we someday see the dinosaurs that appeared in the movie Jurassic Park, in which a team of genetic scientists created a wildlife park of de-extinct dinosaurs?
Read the article and learn about the resurrected dire wolves.
