There was a study about humpback whale songs spreading between different whale populations few years back. New songs were apparently invented by a whale population that lived along the Australian coast from Sydney to Tasmania. Later they traveled to Antarctica where populations from Patagonia also summered. The South American whales picked the Australian whale songs, then spread them up both sides of the continent. It went to the galopagos islands and from there to Hawaii. From Hawaii, spread to Alaska and Pacific Northwest. Meanwhile the Australians were making new songs that also spread up the Australian coast to populations in the equatorial pacific.
