I'm not sure if it's the birth of ska, but it's at least adjacent.
From the description ""Simmer Down" was the first single released by The Wailers, accompanied by the ska supergroup, The Skatalites, and produced by Clement "Coxsone" Dodd in 1963. It was the number one hit in Jamaica in February, 1964."
from the comments
"this is what happened when the primarily calypso musicians in Jamaica started listening to American doo wop which resulted in an upbeat called ska.
