Adaptive evolution arises when heritable genetic variation confers a fitness advantage under changing environmental or ecological conditions. Central mechanisms include the generation of variation ...

A comparative genomic study of 12 pig family species reveals lineage-specific immune gene loss, interleukin-1 family ...

Charles Darwin's theory of evolution generated scientific debate and discussion not only in Darwin's own time, but for decades afterward. In the latter part of the nineteenth century and the until the ...

Structural variants (SVs) are alterations in the DNA sequence that involve large-scale changes, typically longer than 50 base pairs. Advances in long-read sequencing have significantly increased ...

In a first-of-its-kind experiment tracing evolution across 25 generations, scientists have discovered that marine copepods—the tiny crustaceans at the heart of the ocean food web—rely on a largely ...

Scientists have identified an unexpected source of genetic variation in human sperm that occurs earlier in sperm development than previously thought. Published in Nature, researchers at the Wellcome ...

Some scientists say humans may be entering a new phase of evolution, one in which culture is becoming more powerful than genes in shaping our survival and future. At the heart of that idea is a ...
