How does a single cell build a brain with billions of precisely organized neurons? Researchers suggest that brain cells use their lineage—their cellular family tree—as a kind of positional map. Cells that come from the same ancestor stay near one another, helping the brain organize itself without relying solely on chemical signals.

How our #cells evolved: #Genome analysis rewrites the origin of the first #eukaryotes
Using the MareNostrum supercomputer, researchers at BSC-CNS and IRB Barcelona discover that the first complex cells emerged from a gradual, millions-year alliance involving giant #viruses and multiple bacterial groups
Published in Nature, the team led by Dr. Toni Gabaldón used the MareNostrum supercomputer to reconstruct the genetic origin of the last common ancestor of all eukaryotes—the cellular lineage to which animals, plants, fungi, and protists belong. The study challenges the idea that cellular complexity emerged from a single evolutionary encounter, pointing instead to a gradual process of interactions among different microorganisms that lasted for millions of years. The findings, which culminate more than five years of computational work, identify contributions from several bacteria in addition to the one that gave rise to mitochondria, and suggest that giant viruses may have acted as vehicles for gene transfer.
