Bioluminescence is woven into folklore legends. From the 8th century Japanese firefly legend known as hotaru, to Fox an Apache American Indian who spread fire over the Earth during festive dance with fireflies, the world-wide wonder of bioluminescence is interlaced throughout the expanse of nature from the microbe to vertebrates.
To explore the science of ancient legends, evolutionary biologist Matthew Davis at St. Cloud State University in Minnesota, published the results of their study in the paper entitled “Repeated and Widespread Evolution of Bioluminescence in Marine Fishes” in the journal PLoS One (2016). Despite the inference in the title, however, evidence for the origin of bioluminescence continues to stymie scientists.
New Evolution Dilemma
A new and unanticipated evolution dilemma now follows the wake of a massive new microbe discovery. Using a new technique, the number of known bacteria has been “bolstered by almost 50 percent,” according to a new article by Kevin Hartnett published in QuantaMagazine.org and re-printed in ScientificAmerica.com.
With a series of successively smaller porous filters, the University of California Banfield Group at Berkley, discovered a massive number of tiny “bacteria representing > 35 phyla… that consistently distinguished these organisms from other bacteria.” Travis Bedel’s illustration displays the magnitude of the discovery. These newly discovered ultra-small microorganisms, however, accentuates the long-standing dilemma between the theory of evolution and the scientific evidence. Continue Reading
