Bacteria3
  • Phys.org) -- Researchers working at a lab at Berkeley University, led by Nicole King, have uncovered the first example of a kind of bacteria that causes a single celled organism to form a colony, a finding that has implications for researchers looking into the origins of multi-celled organisms in general. (phys.org)
  • The findings have added importance because researchers have long thought that choanoflagellates are animals closest relative, which means that it's possible that bacteria and the molecules they produce, could conceivably be part of the reason that single celled organisms first began to form colonies, leading eventually to multi-celled beings that evolved over time into all of the animals that are alive today. (phys.org)
  • Not everyone is onboard with that idea however, as over time, choanoflagellates have evolved just as have all the organisms that evolved from whatever the first multi-celled organisms actually were, but this new finding does hint at the possibility that we all owe our existence to a bacteria similar to A. machipongonensis living all those years ago. (phys.org)
