* Ancient Origins: Salmon belong to the family Salmonidae, which likely originated in the North Pacific Ocean around 50 million years ago.
* Evolution and Migration: Over time, they diversified and spread, adapting to various environments. Some species evolved to live in freshwater lakes and rivers, while others remained in the ocean.
* Global Distribution: Today, salmon are found in the North Pacific, North Atlantic, and Arctic Oceans, as well as in many rivers and lakes in the Northern Hemisphere.
So, while we can't pin down a single location as the "first place" salmon existed, their origins are most closely tied to the North Pacific Ocean.
