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.
