Yes, we thought maybe you would:
The network of nerves connecting our eyes to our brains is sophisticated and researchers have now shown that it evolved much earlier than previously thought, thanks to an unexpected source: the gar fish.
Michigan State University’s Ingo Braasch has helped an international research team show that this connection scheme was already present in ancient fish at least 450 million years ago. That makes it about 100 million years older than previously believed.
“It’s the first time for me that one of our publications literally changes the textbook that I am teaching with,” said Braasch, as assistant professor in the Department of Integrative Biology in the College of Natural Science.
This work, published in the journal Science on April 8, also means that this type of eye-brain connection predates animals living on land. The existing theory had been that this connection first evolved in terrestrial creatures and, from there, carried on into humans where scientists believe it helps with our depth perception and 3D vision.Michigan State University, “A Discovery That “Literally Changes the Textbook”” at Neuroscience News
Isn’t this becoming a trend? Textbook Darwinism is surely a hindrance to the student who must learn and regurgitate the “narrative” while, if the interest is there, learning the facts by other means.
Researchers: Microbes have been “at an evolutionary standstill” for 175 million years? Researcher: “The best explanation we have at the moment is that these microbes did not change much since their physical locations separated during the breakup of supercontinent Pangaea, about 175 million years ago,” Stepanauskas said. “They appear to be living fossils from those days. That sounds quite crazy and goes against the contemporary understanding of microbial evolution.”
Günter Bechly: Paper says Cambrian Explosion took only 410,000 years From the paper’s media release: Moreover, the scientists’ data series reveal that the development of the fauna took place within a very short period. The transition from the “Ediacara biota” – multi-celled but very simply organisms – to the diverse Cambrian life forms occurred over less than 410,000 years.
