The First Example of Hybrid Speciation in Ancient DNA The new study has also amplified the ability for researchers to track the evolutionary process of speciation – the formation of new and distinct species. A Nature press release states that this process generally occurs “over time periods that are thought to be beyond the limits of DNA research.” A tusk from a woolly mammoth discovered in a creek bed on Wrangel Island in 2017.

Adycha and Chukochya are believed to be members of a species that spawned the woolly mammoth, but Krestovka appears to come from an unknown, and possibly entirely new, mammoth lineage.
