Million-Year-Old DNA Rewrites Mammoths' Evolutionary Tree

Million-Year-Old DNA Rewrites Mammoths' Evolutionary Tree

DNA from three ancient molars, one likely to be over a million years old, has revealed that there is a ghost lineage of mammoths that interbred with distant relatives to produce the North American mammoth population.

For months, these researchers had been periodically doing similar genomic surveillance work to keep tabs on the dozens of strains of SARS-CoV-2 that were circulating around the country, looking for any problematic mutations in the virus’s spike protein.

By combining DNA sequence data with gene expression profiles from deer, goats, and sheep, the consortium scientists identified a handful of genes that work together to keep such species cancer-free, even as they grow pounds of new tissue on their heads each year.

Dun Dun. Duun Duuun! The Great White Shark Genome Is Here

The Great White Shark Genome Is Here Sharks are renowned for their wound healing, lifespans of 70-odd years, and low rates of cancer. Stanhope and Shivji’s new map reveals that great white sharks also possess huge chunks of code for these genome-stabilizing DNA repair mechanisms and for tumor suppression.

“It’s important to note that, right now, the medical profession is not recommending this for healthy patients,” Green says.And while Veritas’ test covers 200 genetic predispositions for disease compared to 23andMe’s nine, customers might decide that information isn't worth $1,000—Veritas will be competing with companies like 23andMe on the perceived value of all that genetic information until it can accomplish the sub-$200 genome.To get ahead in that regard, Veritas wants to integrate genetic data into the everyday.

The Evolutionary Importance of Neutral vs. Adaptive Genes

The Evolutionary Importance of Neutral vs. Adaptive Genes

For most of the first half of the 20th century, population geneticists largely attributed genetic differences between populations and species to adaptation through positive selection.Motoo Kimura proposed in 1968 that most mutations might be neutral in effect rather than beneficial or harmful, and that shifts in the frequency of these neutral mutations dominated evolutionary change at the genomic level.Annual ReviewsBut in 1968, the famed population geneticist Motoo Kimura resisted the adaptationist perspective with his neutral theory of molecular evolution.
