Happy to share the latest manuscript from our lab, in which we propose that eukaryotes evolved from a genomic chimera of Asgard archaea and giant viruses.

This is a controversial topic, but we believe we have strong evidence to suggest a critical viral role in eukaryogenesis.

Scientists discover first nitrogen-fixing organelle
Meaning: #eukaryotes CAN do
#NitrogenFixation

wow. A scientific fact I mentioned in several of my books is no longer true. Also, all biology / biochemistry textbooks need to be updated. Oh well. Exciting to see such a major change though.
