New limits to functional portion of human genome reported

An evolutionary biologist at the University of Houston has published new calculations that indicate no more than 25 percent of the human genome is functional. That is in stark contrast to suggestions by scientists with the ...

Examining the source behind Sherpa mountain fitness

The Sherpa population in Tibet is world-renowned for their extraordinary high-altitude fitness, as most famously demonstrated by Tenzing Norgay's ability to conquer Mount Everest alongside Sir Edmund Hillary. The genetic ...

Foxtail millet genome sequence completed

BGI, in cooperation with Zhangjiakou Academy of Agricultural Science, has completed the genome sequence and analysis of foxtail millet (Setaria italica), the second-most widely planted species of millet. This study provides ...

Plants with pocket-sized genomes

Members of Genlisea, a genus of carnivorous plants, possess the smallest genomes known in plants. To elucidate genomic evolution in the group as a whole, researchers have now surveyed a wider range of species, and found a ...

Rabbits like to eat plants with lots of DNA

Rabbits prefer to eat plants with plenty of DNA, according to a new study by Queen Mary University of London and Royal Botanic Gardens, Kew.

Ornithologists discover flight causes genome shrinkage

(Phys.org) —It has long been known that birds and bats have small genomes, but the cause was uncertain. Now researchers at the University of New Mexico have shown that the genome shrinks over evolutionary time in species ...

Evolution can cause a rapid reduction in genome size

(PhysOrg.com) -- It would appear reasonable to assume that two closely related plant species would have similar genetic blueprints. However, scientists from the Max Planck Institute for Developmental Biology in Tübingen, ...
