An article in Science describes the research of evolutionary biologists, including Matt Herron and Will Ratcliff, members of the NASA Astrobiology Institute’s Georgia Tech team, in examining the mechanisms that enabled the transition from single cells to multicellular life. Across a variety of organisms, the researchers found that a series of small genetic steps may have been responsible for the shift to multicellularity.

The story includes this video highlighting the work happening at their lab.
