Scientists from the UK recently conducted a detailed re-examination of a fossilized Prototaxites species found in ...

and different from eukaryotes. However, until scientists determined the position of the LUCA (what evolutionary biologists call the root position) in the tree, all three domains appeared equal.

In the three-domain model, eukaryotes belong to a separate branch that shares a common ancestor with archaea. But phylogenetic analyses suggest that complex cells emerged from within the archaea. This ...

Asgard archaea may have led to the evolution of eukaryotic life ETH Zurich researchers identify actin and microtubule ...

Scientists have debated where Prototaxites belong in the tree of life for over a century, but now a new study suggests it ...

There are two major types of hypothesis about how eukaryotes and their nuclei may have originated (Poole & Penny 2007). One of these involves fusion between cells from domains Archaea and Bacteria ...

Scientists reveal the role of hidden microbes called Asgard archaea in the origins of complex life, challenging long-held views of evolution.
