Are Scientist Making an Animal Like the Woolly Mammoth The pigeons are outwardly unremarkable. Thirteen birds, ages two weeks to three months, occupy a coop at an fauna inquiry facility west of Melbourne, Australia. They're descendants of the common rock dove, recognizable denizens of city squares and park benches—with 1 small just crucial distinction. These are the outset pigeons in history with reproductive systems that incorporate the Cas9 gene, an essential component of the Crispr gene-editing tool . The squabs of this flock will be born with the Cas9 cistron in every one of their cells, allowing scientists to edit their offspring with DNA from the extinct passenger dove. Those birds, if everything goes to plan, will be the commencement live animals edited with traits from a species that no longer exists. The flock was created by Ben Novak, an American scientist who has spent the past half dozen years working obsessively on a process known as de-extinction.
