QUOTE: “'Already at 3.2 billion years ago, we see evidence of differences in mat-forming microbial communities suggesting that some were likely better adapted for life in the ocean versus on land,” says Homann."

DAVID: This just adds to the evidence that life started very early on the newly formed Earth.

It also adds to the evidence that the earliest forms of life were possessed of a mechanism that enabled them to adapt to different environments. Note the term “communities”. All multicellular adaptations and innovations require intelligent cooperation between cells. That may be a sign that the intelligence actually comes from the cells.
