"Traveling globally, one notices the same suite of species in many cities ... biological invasions creating a kind of global Cuisinart where the urban biota becomes homogeneous."

This time the issue was much simpler — as the authors themselves wrote, “the discovery emphasizes that terrestrial biota can rapidly colonize extraterrestrial specimens even given contamination control precautions.”

Understanding the formation and biota of these structures could provide important clues to the origin and ecology of early life on our planet.

Moreover, this biota was once located very close to the South Pole, revealing the composition of Ordovician southernmost ecosystems.

And when emoji biota are limited, the ecologists argue in a new paper, so is the scope of the natural world that we can talk about, advocate for and ultimately protect.
