Researchers have resurrected woolly mammoth genes, from one of the last known mammoth populations, in the lab. These mammoths were believed to have suffered genetic defects, and in tests the team found that the genes did not function normally.
The Pleistocene Park project is aiming to rebuild a lost Ice Age ecosystem in Siberia, and its directors, Sergey and Nikita Zimov, say it could help slow the effects of climate change. Now, the initiative is running a crowdfunding campaign to help transport a new herd of animals to the park.
While there has been some talk of bringing the wooly mammoth back to life, scientists would need to be careful with the genetic material they start with. It turns out that just before they went extinct, the massive herbivores had what researchers are calling a "genomic meltdown."
