Colossal Biosciences, which aims to revive extinct species, has raised an additional $200 million. Critics say de-extinction in its purest sense isn’t possible. Scientists say they are close to ...
Some mammals declared as extinct may very well reappear. [1] For example, a study found that 36% of purported mammalian extinction had been resolved, while the rest either had validity issues (insufficient evidence) or had been rediscovered. [3] As of December 2015, the IUCN listed 30 mammalian species as "critically endangered (possibly ...
From the pygmy tarsier (a mouse-sized big-eyed animal that weighs almost 60 grams) to the Coelacanth (the closest link between fish and the first amphibian creatures which made the transition from ...
