A groundbreaking study suggests that the famous Cambrian explosion—the dramatic burst of diverse animal life—might have actually started millions of years earlier than we thought. By analyzing ancient ...

The origin of organisms with complex cells, known as eukaryotes, is one of the most crucial parts of life’s evolutionary story. All animals, plants, and fungi are eukaryotes, and if complex cells had ...

Using genetic discoveries based on modern bioluminescent organisms, scientists have estimated coral bioluminescence to have originated in the Cambrian period, about 540 million years ago. This finding ...

The Universitat Autònoma de Barcelona (UAB) forms part of an international consortium that is preparing the Tree of Sex project, an ambitious initiative aimed at decoding the evolutionary complexity ...

The molecular clock theory posits that genetic changes happen steadily and gradually, offering a reliable means for peering into the past and theorizing when complex life first emerged. However, there ...

PART 1: THE HISTORICAL FRAMEWORK: EVOLUTION AS SCIENCE: Before Darwin -- Darwin and natural selection -- The arguments and the evidence for evolution -- PART 2: ORIGINS: THE ENORMITY OF TIME: The ...

Sleep helps even things out. It was Darwin's great insight that natural selection was the primary factor driving the evolution of organisms. His detailed research ultimately lead to the acceptance by ...

An international team of researchers, led by Danielle DeLeo from the Smithsonian Institution, has identified eight organisms with previously unknown luminosity. Using genetic findings from these ...
