There was an ancient paradigm about the «fitness cost of antibiotic resistance,» but the emergence of the new technologies of high - throughput sequencing has changed the field, allowing researchers to study bacterial pathogenesis at the genome scale,» said Dr. David Skurnik, senior author of a new Bioessays article.

New DNA recovery and sequencing technology is at last allowing scientists to assemble entire genomes of ancient scourges — and elusive modern ones

Accessing Ancient Genomes — New techniques and very old bones pushed back the limits of genome sequencing for our early ancestors.

New techniques and very old bones overcome the limits of genome sequencing for prehistoric horses, ancient cave bears, and even our own early ancestors.

This new work, which hints that other horses may be represented in these ancient genomes, shows «that [horse] domestication could have been a process with many phases, experiments, failures, and successes,» says Ernest Bailey, a geneticist at the University of Kentucky's Gluck Equine Research Center in Lexington.

A new study uses ancient DNA to suggest that a massive migration of herders from the east shaped the genomes of most living Europeans — and that these immigrants may have been the source of Proto - Indo - European (PIE), the mysterious ancestral tongue from which the more than 400 Indo - European languages sprang.

Browning's team used a new technique to trawl for segments of ancient DNA in the genomes of 5600 living humans from Europe, Asia, America and Oceania.

The study broke new ground in other areas as well, yielding the first ancient whole genomes of East Asian ancestry and the highest coverage ancient human genome from Asia (7x coverage) sequenced to date.

The sequencing of ancient genomes is still so new, and it's changing the way we reconstruct human origins

Palaeontologists don't know what the Denisovans looked like, but studies of DNA recovered from their teeth and bones indicate that this ancient population contributed to the genomes of modern humans, especially Australian Aborigines, Papua New Guineans and Polynesians — suggesting that Denisovans might have roamed Asia.

... modern humans exist in environments that are critically different from those in which we evolved, and that our new environments interact with our ancient genomes to lead to disorder... In this perspective, these functions may or may not be adaptive in modern environments, but historically accomplishing these functions has promoted fitness and that is why the symptoms of depression have evolved.

However, the ultimate factor underlying diseases of civilization is the collision of our ancient genome with the new conditions of life in affluent nations, including the nutritional qualities of recently introduced foods.
