New research challenges the idea that all complex life shares a single ancestor, suggesting instead a collective of related organisms.
Revising the origin of life
Recent research suggests that the last common ancestor of all complex forms of life on Earth may have been a collective of related organisms rather than a single entity.Traditional view of evolution
Traditionally, the evolution of life has been visualized as a multi-branched tree, with the trunk representing the common ancestor.New findings challenge old ideas
However, new findings indicate that this ancestor is more likely a group of related organisms rather than a single cell or organism.Evidence from unicellular relatives
Studies on distant unicellular relatives are accumulating evidence that complex life forms are descended from a cellular collective rather than a single ancestor.Research still ongoing
The exact composition of this collective and the specific partners involved remain to be determined, as scientists continue to investigate this new hypothesis.
