A major event in the evolution of organisms on earth was the development of complex, multicellular life forms made of eukaryotic cells, which are thought to have come from prokaryotic cells. Studies ...

Scientists have spent decades cataloging life on Earth’s surface, from rainforest canopies to ocean trenches. But a growing body of research now shows that a vast, hidden biosphere thrives kilometers ...

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 ...

An interdisciplinary team of mathematicians, engineers, physicists, and medical scientists has uncovered an unexpected link between pure mathematics and genetics, that reveals key insights into the ...

Aerobic respiration began hundreds of millions of years earlier than previously thought, a new study suggests.

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 ...

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 ...

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 ...
