Population genetics
Population genetics is the study of the distributions and changes of allele frequency in a population, as the population is subject to the four main evolutionary processes: natural selection, genetic ...

The true story of George Price, the scientist who discovered the equation for altruism and gave himself away
Laura met George in the pages of Reader’s Digest. In just a couple of column inches, she read an abridged version of his biography and was instantly intrigued. In the 1960s, apparently, egotistical sc...
We Were Wrong About How Ancient Humans Colonized North America
It’s a veritable certainty that North America’s first people arrived via the Bering Land Bridge, but less certainty exists about how and where they migrated from there. For years, scientists thought t...
Calls vs. Balls: "Monkey Balls" Show Why Men Overcompensate
Howler monkeys are about the size of a small dog, weighing around seven kilos, yet they are among the loudest terrestrial animals on the planet, and can roar...
Resistance To HIV Drug Growing, Study Finds
HIV resistance to the antiretroviral drug tenofovir (Viread) is increasingly common, a new study finds. The researchers said their finding is surprising and alarming because the drug plays a major rol...
Grabbing A Parasite By The Tail: U-M Team Solves "Jumping Gene" Mystery
Deep within your DNA, a tiny parasite lurks, waiting to pounce from its perch and land in the middle of an unsuspecting healthy gene. If it succeeds, it can make you sick. Like a jungle cat, this para...
Video: Man Claims He Caught Three-Eyed Fish In Gowanus Canal
If the man in the video is to be believed, the first Gowanus Canal monster is your regular run-of-the-mill three-eyed fish. It was always only a matter of time until the putrid toxic waters of the Gow...
Researchers Find Variation In Gene For Brain-Derived Neurotropic Factor Which Could Impact Obesity
A team of researchers claims that they have found variation in a gene for brain-derived neurotropic factor (BDNF), which could have an impact on obesity among adults and children. The study researcher...
Rare Mutation May Extend Survival In Lung Cancer Patients With Brain Metastases
Most patients with non-small cell lung cancer (NSCLC) that has metastasized to the brain have a dire prognosis. But Yale researchers have identified a subset of those patients with a rare genetic muta...
Calls Vs. Balls: Monkeys With More Impressive Roars Produce Less Sperm
Howler monkeys are about the size of a small dog, weighing around seven kilos, yet they are among the loudest terrestrial animals on the planet, and can roar at a similar acoustic frequency to tigers....
Mutant Plant Munches TNT, Could Help Solve Cleanup Problems
A new study suggests that a mutant variety of a cabbage relative thrives on TNT, pointing the way to a potentially elegant solution for millions of acres of contaminated land. The plant, Arabidopsis t...
How Chronic Inflammation Can Lead To Cancer
Researchers discover how the immune system can create cancerous DNA mutations when fighting off infection. Chronic inflammation caused by disease or exposure to dangerous chemicals has long been linke...
Out Of Africa, By Way Of Egypt: New Genetic Data Points To Egyptian Route For Original Human Migration
Scientists may be one step closer to tracing the exodus of modern humans out of Africa. New genetic evidence points to a northern route leading out of the continent, which may just settle a long-dispu...
Human Hunting Weapons May Not Have Caused The Demise Of The Neanderthals
The demise of Neanderthals may have nothing to do with innovative hunting weapons carried by humans from west Asia, according to a new study. The researchers say their findings mean that we may need t...

Mutation
In biology, a mutation is a permanent change of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. Mutations result from damage to DNA whic...

Genetic genealogy is the use of DNA testing in combination with traditional genealogy and traditional genealogical and historical records to infer relationships between individuals. Genetic genealogy...
Selection
In the context of evolution, certain traits or alleles of genes segregating within a population may be subject to selection. Under selection, individuals with advantages or "adaptive" traits tend to b...
