What are eukaryotes?

Eukaryotes are complex cells that have a nucleus and other membrane-bound organelles.

What are syntrophic peptidotrophic archaea?

Syntrophic peptidotrophic archaea are a type of archaea that live in symbiotic relationships and obtain nutrients by breaking down peptides.

What are the implications of this discovery?

The discovery of archaea closely related to eukaryotes has significant implications for our understanding of life's origins.
