we are an Organism not a Bacteria - Science Nordic article

Science Nordic article...

We are made from Organisms not Bacteria like once thought! This is a really cool article about our biological makeup. Had to share, since we talk about bacteria a lot on this forum.

Archaea are not bacteria

It is a combination of the genealogical tree, where Lokiarchaeota is a sister group to eukaryotes and the discovery of core genes from the the eukaryotes’ tool box which have convinced the scientists that they have found a missing link.

The discovery of a new microorganism, Lokiarchaeota, shows that the ancestor of all complex life (eukaryotes) was an archaeon. The tree of life should therefore be redrawn so that eukaryotes–fungi, plantes, animals and humans–originate from the domain of the archaea.

“This is really exciting,” says Professor Emeritus Roger Garret, head of the Danish Archaea Centre at the University of Copenhagen.

“It strongly underpins the archaea as evolutionarily different from bacteria and shows that we–the eukaryotes–stem directly from archaea-like organisms and not bacteria,” he says.

The geobiologist Daniel Mills from the Nordic Centre for Earth Evolution at the University of Southern Denmark is enthusiastic.

“This is a very promising find. The method demonstrates a testable way of constructing the host that is the ancestor of all conemporary eukaryotes. By continuing the search for the closest relatives of eukaryotes we can hopefully narrow the enormous gap that dissociates eukaryote life from that of archaea and bacteria,” says Mills.

Well that's more like it. I never did think much of the claim that I was related to a bacteria. And I've never been a bacteria fan, either.

Thanks for the link.

Interesting, Erica. Thanks.
