Saw this weeks ago and decide to share it with gather eventually:
It is referred to as LUCA, the Last Universal Common Ancestor. Â Scientists don't know much about this postulated ancestor of all life on earth. Many suggest that LUCA was little more than a crude assemblage of molecular parts, a chemical soup out of which evolution gradually constructed more complex forms. Some scientists still debate whether it was even a cell.
However, "New evidence suggests that LUCA was a sophisticated organism after all, with a complex structure recognizable as a cell, researchers report. Their study appears in the journal Biology Direct."
