Repeat act: Parallel selection tweaks many of the same genes to make big and heavy mice
Organisms are adapted to their environment through their individual characteristics, like body size and body weight. Such complex traits are usually controlled by many genes. As a result, individuals show tremendous variations and can also show subtle gradations. Researchers from the Max Planck Institute for Evolutionary Biology in Plön have ...
Repeat act: Parallel selection tweaks many of the same genes to make big and heavy mice
(Max-Planck-Gesellschaft) Max Planck scientists decode genes for a complex characteristic.
Evidence Of Darwinian Selection Still Influencing Human Evolution
New evidence proves humans are continuing to evolve and that significant natural and sexual selection is still taking place in our species in the modern world. Despite advancements in medicine and technology, as well as an increased prevalence of monogamy, research reveals humans are continuing to evolve just like other ...

Blog posts respond to selection of Jim Yong Kim to lead World Bank
The World Bank on Monday selected U.S.-nominated Jim Yong Kim, a Korean-American physician and anthropologist, as its new president. The following is a summary of blog posts and commentary published in response to his election.
Cure of ADPKD by selection for spontaneous genetic repair events in Pkd1-mutated iPS cells
A research group including Kyoto University researchers demonstrates that mouse iPS cells, in which genetic correction occurs spontaneously through mitotic recombination, is selectable from the population of genetically mutated iPS cells in the mouse model of autosomal dominant polycystic kidney disease (ADPKD). This technology could be applicable of genome editing ...
A bug’s (sex) life: Diving beetles offer unexpected clues about sexual selection
Studying female reproductive tracts and sperm in diving beetles ( Dytiscidae ), researchers from the University of Arizona and Syracuse University have obtained a glimpse into a bizarre and amazing world of sperm that can take on a variety of forms including joining together into conglomerates that navigate the ...
Meet the beetles: Social networks provide clues to natural selection
Think of them as a group of guys, hanging out together, but not spending much time with the ladies, nor getting much "action." Except these "guys" are forked fungus beetles.
Teaching skills key to selection of a successful model farmer
Nairobi, 15 November 2011 Farmer trainers should be selected based on their interest and ability to teach others rather than on their successes in implementing farming techniques, shows a new study led by Steve Franzel, a scientist at the World Agroforestry Centre (ICRAF). In the study ...
Novel link between cell surface sugars, Darwinian sexual selection, and immune function
Researchers at the University of California, San Diego School of Medicine say that losing the ability to make a particular kind of sugar molecule boosted disease protection in early hominids, and may have directed the evolutionary emergence of our ancestors, the genus Homo.
Sexual Selection By Sugar Molecule Helped Determine Human Origins
