Organisms in the Eukarya domain are made of the more complex eukaryotic cells. These organisms, called eukaryotes, can be unicellular or multicellular and include animals, plants, fungi and protists.

Prokaryotic cells, which include all bacteria and archaea, are ancient, and relatively simple compared to eukaryotic cells, which are found in fungi, plants, and animals. Scientists have long sought ...

A mysterious tar-like liquid appeared on the deck of the R/V Blue Heron, a research vessel exploring Lake Superior. When the researchers tested the substance, they found unusual organisms. Now they ...

Microbes may be miniscule, but they have a massive impact on Earth and its habitability. They are uniquely different from animals, plants, and other eukaryotic organisms in that they can gain ...

Then, to examine their hypothesis more directly, Ratcliff and Bingham created a highly simplified computational model. In the model, populations of prokaryotes and eukaryotes were under pressure to ...

One flip, and your brunette locks are platinum blond. That's not too far from what happens in some prokaryotes, or single-cell organisms, such as bacteria, that undergo something called inversions.

Relatives of the two rudimentary organisms, called prokaryotes, survive as bacteria and related microbes. But they also at some point combined, producing eukaryotes, some scientists assert.
