From above...
Other speciation events seem to result from major changes in chromosomes, which suddenly leave some individuals unable to mate successfully with their neighbours.
...this year's entry for the 'foot in mouth award'?

Again, it would ultimately be more impressive if someone could define (and obtain consensus on) "species."
The word is thrown around with such abandon it's like mashed potatoes in a food fight.

But that comment Min surely leads to extinction of that specimen? If it can't reproduce it's a dead end.

Well, yeah. One organism born with a different number of chromosomes would, assuming it survives, have a tough time passing along its genes no matter how successful it were in other aspects of life.
It takes two to .... screw, or something.
