Conditions in rural England around the turn of the 20th century offer a case study for cultural evolution researchers.

People with a common history – often due to significant geographic or social barriers – often share genetics and language. New research finds that even a dialect can act as a barrier within a group.
The genetic evidence behind why some people suffer longer term concussion effects is growing. But what are the ethical considerations that flow from that knowledge when it comes to sport?
Statistical pitfalls in GWAS can result in misleading conclusions about whether some traits (like long horns or spotted skin, in the case of dinosaurs) are genetically linked.

People don’t randomly select who they have children with. And that means an underlying assumption in research that tries to link particular genes to certain diseases or traits is wrong.

A new study hopes to produce a catalogue of human genetic variation and assess the burden of noncommunicable diseases in 100,000 adults in Nigeria.
A complete human genome, seen here in pairs of chromosomes, offers a wealth of information, but it is hard connect genetics to traits or disease.

The first full human genome was sequenced 20 years ago. Now, a project is underway to sequence 1 million genomes to better understand the complex relationship between genetics, diversity and disease.

Fundamental research has informed what we know about coronaviruses up until the pandemic. With possible future outbreaks, continuing and developing this type of work is crucial.
Africa is known to be where humans originated. This makes it the most genetically diverse region in the world. Diversity in other populations represents a subset of the diversity within Africa.
Why was one gene mutation that affects hair, teeth, sweat glands and breasts ubiquitous among ice age Arctic people? New research points to the advantage it provided for ancestors of Native Americans.
As genes are favored or phased out, human evolution continues.

Comparing genomes of more than 200,000 people, researchers identified genetic variants that are less common in older people, suggesting natural selection continues to weed out disadvantageous traits.
It’s in the genes why some people find broccoli unpleasantly bitter, but others barely flinch when eating it.

Scientists of all kinds turn to computer models to investigate questions they can’t get at any other way. Here’s how models work and why we can trust them.
Scientific evidence shows overwhelmingly that people across the world are genetic refugees from Africa.

Despite science refuting the existence of different human races, people have used “race” throughout history to divide and denigrate certain people while promoting their claims of superiority.
