Researchers suggest that evolution may speed up dramatically during certain periods, challenging a long-held theory and helping explain a puzzling 30-million-year gap between genetic estimates and the ...

Scientists have helped to construct a detailed timeline for bacterial evolution, suggesting some bacteria used oxygen long before evolving the ability to produce it through photosynthesis. University ...

Here's what you'll learn when you read this story: The famous analogy goes that if all of Earth's geologic history was compressed into a single calendar year, modern humans wouldn't make an appearance ...

Bacteria are the most diverse organisms on Earth, with a number of species that's difficult to quantify. They're also incredibly old Bacteria consist of a single cell. They do not have bones and are ...

Long before vertebrates walked on land, millipedes had the place to themselves. Hundreds of millions of years before ...

The story of primates is a tale of incredible variety and ancient roots, told through the lens of science, DNA, and time itself. These creatures, ranging from massive gorillas to tiny mouse lemurs, ...

A team from the University of Illinois has uncovered surprising evolutionary links between the genetic code and tiny protein fragments called dipeptides. By analyzing billions of dipeptide sequences ...

The study, published in Nature Ecology & Evolution, shows that early interactions between fungi and algae may have played a key role in the spread of life across the continents "As a group, fungi are ...
