The Indigenous peoples of the Bolivian highlands are survivors. For thousands of years they have lived at altitudes of more than two miles, where oxygen is about 35 percent lower than at sea level.

The human brain is the most complex system we’re currently aware of. Learning the genetic basis for its evolution, and the changes that distinguish Homo sapiens from our closest relatives, could ...

Scientists at the Institut Pasteur and McMaster University have discovered that the evolution of a gene in the bacterium that causes bubonic plague, Yersinia pestis, may have prolonged the duration of ...

Researchers at the University of Maine are theorizing that human beings may be in the midst of a major evolutionary shift — driven not by genes, but by culture. In a paper published in the Oxford ...

Researchers at the University of Maine are theorizing that human beings may be in the midst of a major evolutionary shift—driven not by genes, but by culture. "Human evolution seems to be changing ...

The genetic code acts as life’s instruction manual, telling cells how to build proteins from DNA and RNA. Though it's a marvel of molecular precision, the path it took to evolve remains unclear. Fresh ...

Human evolution has often been depicted as a process of adaptation, where natural selection and genetic changes drive species toward better-suited traits for survival in their environments. But this ...

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 ...

Mitochondria are known as the body’s “energy factories,” and their function is essential for life. Inside mitochondria, a set of complexes called the oxidative phosphorylation (OxPhos) system ...

The vaginal microbiome, a complex ecosystem inhabited by diverse microbial communities, plays a pivotal role in maintaining reproductive health and protecting against infections. Recent advancements ...
