Scientists Closer to Resurrecting Extinct Animals Using Genetic Engineering Techniques
TLDR Scientists are making progress in resurrecting extinct animals like the woolly mammoth and potentially even dinosaurs using genetic engineering techniques like CRISPR. While they have discovered fossils and made changes to DNA, true Jurassic Park dinosaurs and fully resurrected mammoths are still a long way off.
Timestamped Summary
00:00
Scientists are closer than ever to resurrecting extinct animals, including the woolly mammoth and potentially even the T-Rex, using genetic engineering techniques like CRISPR.
04:27
Scientists have discovered a fossilized arm of a Tyrannosaurus Rex, which has led to the possibility of extracting DNA and potentially bringing back extinct animals like dinosaurs.
09:11
Scientists discovered red round bodies that looked like blood cells in a fossil, leading to speculation about the possibility of finding dinosaur DNA, but ultimately no actual blood or DNA was found.
13:38
Scientists are attempting to transform chickens to resemble their prehistoric dinosaur ancestors by activating ancestral genes that have been turned off in the course of evolution, but without dinosaur DNA, a true Jurassic Park dinosaur cannot be created.
17:57
Scientists are attempting to genetically resurrect a woolly mammoth within the next six years in order to combat climate change by having the mammoths roam the Arctic and prevent permafrost melting.
22:42
Scientists are using synthetic biology and CRISPR to manipulate the DNA of an Asian elephant cell in order to create a cell that contains a mammoth-y genome, with the goal of resurrecting a woolly mammoth.
26:55
Scientists have made about 50 changes to the DNA of an Asian elephant cell to make it more mammoth-like, and the next step is cloning, but even if they are successful, the result will likely be more like a weird-looking elephant than a true mammoth.
31:11
Scientists have successfully cloned a black-footed ferret named Elizabethan using DNA from a ferret that died in the 1980s, which could help bring genetic diversity to the species and potentially save it from extinction.
