This summer an important fundamental discovery was reported at the Society for Experimental Biology’s annual meeting July 3-6 in Valencia, Spain: hand gestures grew out of fish brains!
Andrew Bass, Cornell professor of neurobiology and behavior, described how he found evidence that illustrates how fish are able to vocalize and communicate via their pectorial fins:
“Using methods to understand how the brain is connected to different muscle groups, we mapped the early development of two systems in the brain that control muscles that allow fish to vocalize and to move their pectoral fins.”
“Using methods to understand how the brain is connected to different muscle groups, we mapped the early development of two systems in the brain that control muscles that allow fish to vocalize and to move their pectoral fins. We found that these systems arise from the same compartment.”
“Evidence that the evolutionary origins of the link between speech and gesturing can be traced to a developmental compartment in the caudal hindbrain of fish.”
This insight can be understood visually by notifying how the pectorial fins in fishes are usually located close to the hind brain – see picture below.

Do you have a radial loop fingerprint? In people who have radial loop fingerprints these are usually spotted on the index finger(s); in the field of hand reading it is a common beliew to associate radial loops with ‘people who do not go with the flow’ – refering to the fact that the radial loop represents sort of the opposite of the much more common ulnar loops. But what are the facts and how do they develop?
The latest research points out that a radial loops might have a connection with the Big Five personality dimension Extraverion (see picture below).
This article presents 10 facts about radial loops:
