Scientists generally agree that eukaryotes, the domain of life whose cells contain nuclei and that includes almost all multicellular organisms, originated from a process involving the symbiotic union ...

Canadian scientists have identified microscopic creatures that are so unlike anything seen before, they had to create an entirely new branch on the evolutionary tree of life to slot them in. A new ...

New studies revise ideas about the symbiosis that gave mitochondria to cells and about whether the last common ancestor of all eukaryotes was one cell or many. Our planet formed a little over 4.5 ...

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 ...
