BLACKSBURG, Va., Sept. 25 (UPI) -- The evolutionary timeline is constantly evolving -- being tweaked to adopt and adapt to new discoveries, new facts, new understandings. Thanks to a geologist at Virginia Tech and a team of researchers from Chinese Academy of Sciences, the storyline of multicellular organisms is likely to be shifted back 60 million years to account for new evidence of complex organisms.
The researchers say their analysis of fossils trapped in the rocks of the Doushantuo Formation in central Guizhou Province of South China -- dating back some 600 million years -- show evidence of cooperation among multiple cells. The phosphorite rocks encase complex multicellular fossils which exhibit qualities of early plants and animals like cell-to-cell adhesion, differentiation, and programmed cell death.
