Learn how one-celled organisms, or single-celled organisms, helped build complex life.

Researchers have discovered that a single-celled organism, a close relative of animals, harbors the remnants of ancient giant viruses woven into its own genetic code. This finding sheds light on how ...

The world is full of unusual unicellular organisms and microbes, many of which have not been discovered yet. In 2017, scientists identified a single-celled marine organism called Chromosphaera ...

Scientists at Nagoya University in Japan have identified the genes that allow an organism to switch between living as single ...

Laboratory chemists are now edging closer to the moment when lifeless molecules first organized into the chemistry that would eventually support complex organisms. By recreating key early-Earth ...

New method reveals chemical signs of early microbial life in ancient Earth rocks, showing photosynthesis evolved much earlier ...

In the world of phylogenetics, there's team sponge and team comb jelly. Which creature roots the animal tree of life—the simple sponge or the more complex comb jelly—has stirred fierce debate among ...

Up until recently, habituation -- a simple form of learning -- was deemed the exclusive domain of complex organisms with brains and nervous systems, such as worms, insects, birds, and mammals. But a ...
