This tree, from 1997, is the work of Norman Pace of the University of Colorado. One branch was our own, the eukaryotes. This branch includes animals, plants, fungi, and protozoans. Eukaryotes ...

His approach to the top of the tree (home to eukaryotes, which wrap their DNA in membrane-bound cell nuclei) would rule biology classrooms for decades. Yet his system is based only partly on ...

In eukaryotic tree, grey dash lines represent stem group eukaryotes. Solid lines denote crown group eukaryotes (LECA plus its descendants). Grey bars at nodes display the estimated age range of ...

thanks to a new study that redefines what it means to belong to our limb on the tree of life. That limb includes all eukaryotes, multi-celled organisms and more complex single-celled organisms ...

(Any eukaryotic lineages that lack mitochondria used to have them and then lost them sometime in evolutionary history.) And across the evolutionary tree, different eukaryotes have evolved or procured ...

Lucy Reading-Ikkanda/Quanta Magazine To understand how evolutionarily distinct the hemimastigote lineage is, imagine the eukaryotic tree splayed out before you on the ground as a narrowing set of ...

It is best considered a member of a previously undescribed, entirely extinct group of eukaryotes,” the team wrote in the study paper. This challenges our understanding of the tree of life itself.

Some scientists have looked for clues within eukaryotes, trying to draw their evolutionary tree. The deepest branches might be more primitive than newer ones, not having acquired the full ...

To understand how evolutionarily distinct the hemimastigote lineage is, imagine the eukaryotic tree splayed out before you on the ground as a narrowing set of paths, which begin with places for ...
