Over the past 10,000 years, evolution in West Eurasia has selected for light skin, red hair and resistance to HIV in humans, ...

For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ordinary ...

A plant geneticist and computational biologist teamed up to decipher the unpredictability of natural and engineered mutations in tomatoes. They discovered some combinations of mutations behave as ...

A bird swoops toward a bright orange-and-black moth resting on a leaf in the Amazon. It pulls up at the last second. The ...

For tens of thousands of years, evolution shaped tomatoes through natural mutations. Then, humans came along. For centuries, we've bred and cherry-picked tomatoes with our preferred traits. Today, ...

Cold Spring Harbor Laboratory scientists created a collection of over 40 tomato strains with natural and engineered mutations that affected fruit size. The strains were grown over several years and ...
