Something I had wondered about all my life.
How on earth do you get fish showing up in every body of water you pretty much ever heard of? When the places are not connected at all? I mean, it’s not like fish fly.
The Washington Post reports that a carp, to take one type, can release a hundred thousand eggs.
So: some researchers fed 8,000 carp eggs to eight mallard ducks, and 18 eggs, it turned out, were still viable after passing through the ducks’ digestive systems one to four hours later.
By which point the birds could be miles away from where they ate that meal.
It’s as simple and logical as that.
Scientists are little kids who grew up and still wondered about duck poop.
