Researchers investigate into the various lineages of Asgard archae, and determine one related to Hods as the ancestor of ...

Scientists have long puzzled over the origins of eukaryotes, the domain of life defined by cells with a membrane-bound nucleus, which includes all animals, plants, fungi, and insects. If they unravel ...

The tiny pantheon known as the Asgard archaea bear traits that hint at how plants, animals and fungi emerged on Earth.

In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes.

A newly discovered promoter element "start" points to a shared regulatory syntax for controlling transcription initiation in ...

The first single-celled organisms with a nucleus originated more than a billion years later than biogeochemical evidence had previously indicated. Amoeba are more closely related to humans than to ...

For billions of years after the origin of life, the only living things on Earth were tiny, primitive cells resembling today’s bacteria. But then, more than 1.5 billion years ago, something remarkable ...

If our genes are so similar, what really makes a eukaryote different from a prokaryote, or a human from E. coli? The answer lies in the difference in gene expression and regulation used. Regulation of ...

Every living organism falls into one of two groups: eukaryotes or prokaryotes, with cellular structure determining which group an organism belongs to. Prokaryotes are unicellular and lack a nucleus ...

For billions of years after the origin of life, the only living things on Earth were tiny, primitive cells resembling today’s bacteria. But then, more than 1.5 billion years ago, something remarkable ...

Just as physicists comprehend the origin of the universe by observing the stars and archeologists reconstruct ancient civilizations with the artifacts found today, evolutionary biologists study the ...
