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 ...

The Mexican tetra and other cave‐dwelling teleosts have emerged as models to investigate the genetic basis of adaptation to perpetual darkness and resource limitation. Comparative genomic and ...

A new review highlights how human evolution has shaped the presence of pathogenic variations in DNA damage repair (DDR) genes, offering a new perspective on why modern populations face increased ...

Genes make us who we are—but are they shaped by chance, natural selection, or something else?

Today, researchers from leading institutions, including the University of Manitoba, Environment and Climate Change Canada, Polar Bears International, the Norwegian Polar Institute, and San Diego Zoo ...

A new genome-based study suggests that ancient sharks like frilled and cow sharks could sit outside the family tree that ...

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Using advanced analysis based ...

Hidden within fish DNA are powerful genetic twists that may explain one of nature’s biggest mysteries: how new species form so quickly. In Lake Malawi, hundreds of cichlid fish species evolved at ...

The human genome is made up of 23 pairs of chromosomes, the biological blueprints that make humans … well, human. But it turns out that some of our DNA — about 8% — are the remnants of ancient viruses ...

Influenza virus research has advanced substantially in recent decades, particularly in understanding genetic reassortment and host adaptation mechanisms ...
