“Understanding phylogenetic trees can be difficult ... “an open-ended space to explore the common ancestry of all species and understand how life continues to evolve.” ...

For decades, biologists have used evolutionary or phylogenetic trees to map how species and genes diverge from common ...

“This is the most exciting and important paper on big questions about eukaryotic origins and the tree of life in years,” said evolutionary ... But it wasn’t clear whether eukaryotes and archaea shared ...
