I ask you for two species and you tell me: Fish, frogs, salamanders, lizards and chickens all have some polyploid species. (I have an easy time looking this up!)
I followed your link and found this:
"... We may have to fundamentally change the way we view evolution," says Professor of Botany Doug Soltis.I confused. In the sidebar it refers to "Fish, frogs, salamanders, lizards and chickens," as you did and then here it refers to "one notable exception being salmon." I think your source is confused too....
... Few animal species are [polyploid], one notable exception being salmon.
Evolution via polyploidy is different. "It's instantaneous," says Soltis. ...
But isn't it interesting that he is talking about evolutionary change that must occur instantaneously. (sort of like me) He says, "We may have to fundamentally change the way we view evolution." I've done that. Maybe you should too.
