Origins of First Eukaryotes Linked to Contributions from Multiple Bacteria and Giant Viruses
A new study published in Nature suggests that the origin of complex eukaryotic cells was a gradual, collaborative process involving multiple bacteria and giant viruses rather than a single evolutionary event. This challenges the long-held theory that the acquisition of mitochondria was the sole turning point for cellular complexity.
Why it matters
This research fundamentally shifts our understanding of evolutionary biology and the origins of life on Earth.
All cells in animals, plants, fungi, and protists share a fundamental characteristic, in that they are eukaryotic cells. These are essentially complex cells with specialized internal compartments. The cells that make up our bodies are no exception.
