Many people are familiar with histamine, a biological molecule that serves as a key driver of allergic reactions and other ...

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 groundbreaking study published in this week’s issue of PNAS by scientists from Israel and Ghana shows that an evolutionarily significant mutation in the human APOL1 gene arises not randomly but more ...

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 ...

Scientists have developed a theoretical model that uncovers the dual role of polyploidy -- organisms carrying extra genome copies -- in evolution. Their findings reveal that polyploidy can stabilize ...

Rachel Robson, assistant professor of biology at Morningside College, and Susan Burns, associate dean for academic affairs, collaborated on an article that was published in the May issue of the ...

Groundbreaking research shows that as men age, harmful genetic mutations in sperm become more common—not just from random chance, but because some are naturally favored. Advanced sequencing revealed ...

Many people hold the view that evolution in humans has come to a halt. But while modern medicine and technologies have changed the environment in which evolution operates, many scientists are in ...

A new computer model suggests that the process of evolution can get better at evolving in the face of environmental change. When you purchase through links on our site, we may earn an affiliate ...

The process of evolution usually takes thousands, millions or even billions of years. But researchers have found a way to condense it into a matter of minutes using a method called 'directed evolution ...
