Gastrointestinal (GI) cancers represent a complex interplay of genetic mutations, epigenetic alterations, and environmental factors. The initiation and progression of these cancers are influenced by ...

It is often assumed that modern humans are no longer evolving. But there is now considerable agreement among scientists that evolution is still affecting our species—and this process is taking place ...

In five cases where vertebrates evolved monogamy, the same changes in gene expression occurred each time. In many non-monogamous species, females provide all or most of the offspring care. In ...

Evidence is mounting that epigenetic marks on DNA can influence future generations in a variety of ways. But how such phenomena might affect large-scale evolutionary processes is hotly debated. The ...

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 ...

Researchers have discovered that infiltrating gliomas, a common brain and spinal cord tumor, are shaped by their genetic evolution and microenvironment, a finding that could lead to more targeted ...

Establishing a new field of science to answer the question of what makes humans unique from our extinct relatives has earned Svante Pääbo the Nobel Prize in physiology or medicine. “Humanity has ...

The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...
