Скачать или смотреть Is Cloning Good? The Science & Ethics Of De-Extinction Technology | The Resurrection Quest - Ep 4/4

The season finale stands at the intersection of all de-extinction technologies - from beloved pets in the present to endangered rhinos, extinct mammoths and vanished ecosystems in the future. Whether it’s cloning for conservation or to deal with personal loss, will cloned animals be good photocopies? In Kenya, rhino IVF is expected to produce a northern white rhino calf on the ground by 2026. But how will this solve the genetic bottleneck that threatens this species anyway?

As Ben Novak plans the rearing and socialisation of baby passenger pigeons with the help of AI in aviaries, critics wonder if modern society is ready to cohabit with a billion birds. In the Siberian Arctic, Nikita Zimov maps the data that backs his plan of reviving a lost ecosystem. But is this enough to delay the terrifying threat of the melting permafrost? And then, the audacious attempt to create a cold resistant elephant with genes borrowed from the mammoth - how will this change evolution, as we know it?
