Dec 20, 2023 · Population genetics focuses on studying how genetic traits and variations are distributed within different populations. By examining DNA samples from individuals across various countries, researchers can identify patterns of genetic diversity that highlight differences and similarities.

In 2010, scientists had assembled just five ancient human genomes, including three Neanderthals. Today, the lab of professor of genetics and of human evolutionary biology David Reich alone has sequenced more than 16,000 ancient humans from around the world.
Biochemists had been studying DNA for nearly three-quarters of a century when Oswald Avery and his team at the Rockefeller Institute in New York City helped establish in the 1940s that DNA is the...
Feb 26, 2024 · Scientists can also create new pieces of genetic material and even add, remove or replace sections of DNA to edit genes. Taken together, these are known as genetic technologies. They offer enormous power to learn more about diseases, develop new varieties of plants to improve food crops, or even fix genetic faults that cause inherited conditions.
Jan 10, 2024 · Their genetic influence on today’s population of southern Europe is much weaker. Previous studies have identified 233 genetic variants that increase the risk of developing MS. These variants, also affected by environmental and lifestyle factors, increase disease risk by around 30 percent.
