In a large-scale environmental DNA metagenomic study of ancient plant and mammal communities, an international team of researchers have analyzed 535 permafrost and lake sediment samples from across the Arctic spanning the past 50,000 years. A trio of woolly mammoths (Mammuthus primigenius) trudges over snow covered hills; behind them, mountains …

The so-called Mount Holly mammoth (Mammuthus sp.) lived approximately 12,800 years ago in what is now New England, a region comprising six states in the Northeastern United States, and potentially overlapped with the first human settlers of the region, according to new research from Dartmouth College. The woolly mammoth (Mammuthus …

According to a new study published in the journal PLoS Genetics, dwindling populations created a ‘mutational meltdown’ in the genomes of the last wooly mammoths, which had survived on Wrangel Island in the Arctic Ocean until about 3,700 years ago. This is an artist’s rendition of a woolly mammoth. Image …
