Geneticists are now "back breeding" these species together to produce offspring closer to the qualities of an auroch. Another idea is to essentially clone the dead animal by taking the...
Resurrecting the extinct species has been a pet project of Harvard University geneticist George Church for more than a decade.
A second option is cloning. Scientists would take a preserved cell from a recently extinct animal (ideally before the last of its kind died) and extract the nucleus. They would then swap this nucleus into an egg cell from the animal's closest living relative and implant the egg into a surrogate host.
An extinct animal has been resurrected by cloning for the first time—though the clone died minutes after birth. Findings revealed January 23 in the journal Theriogenology describe the use of frozen...
Przewalski's horses cloned from a stallion that died in 1998 could help reintroduce much needed diversity to the species that was once declared extinct in the wild.
Colossal Biosciences, a buzzy de-extinction company founded in 2021 by Harvard geneticist George Church and tech entrepreneur Ben Lamm, has chosen three species to pursue: the woolly mammoth, an...
There are broadly three approaches to de-extinction — genetic engineering, cloning, and back-breeding. For cloning to work, you need a preserved cell or full set of chromosomes from the extinct ...
Scientists are preparing ambitious plans to resurrect long-dead animals from Passenger pigeons to woolly mammoths.
Scientists have cloned the first U.S. endangered species, a black-footed ferret duplicated from the genes of an animal that died over 30 years ago.
Dolly-style animal cloning underpins CRISPR livestock, but changes loom for the field. By. Heidi Ledford. Cloned beagles: cloning can generate living animals from cells with complex...
