Italian wall lizards introduced to a tiny island off the coast of Croatia are evolving in ways that would normally take millions of years to play out, new research shows.
Completely unscientific statement. They have no reason to say that it would "normally take millions of years" to adapt in this way. There is absolutely no way of addressing that statement empirically, hence it's just idle speculation. Since it has obviously happened in 37 years, there is no need to pull a "millions of years" explanation out of thin air.
So, I guess 6k years may actually be long enough for all the things that must have taken Millions and Billions of years, then?
