Researchers were able to compare ancient salmon DNA to modern salmon. They collected a wide range of ancient bones to study the fish’s DNA. One sample about 7,000 years old — that’s 3,000 years older than the first pyramid. The most recent was about 150 years old.
And thanks to the DNA from those samples, scientists are able to conclude that Columbia River chinook salmon have lost two-thirds of their genetic diversity since ancient times.
