If the grape plant changed over 650 years, wouldn't we see a drift in the graph over those 650 years? What we're seeing is a sudden burst of "evolution" since the 1950s.

Dunno, maybe it's the nuclear tests, but I'm a bit skeptical to that explanation.




To be fair, there has been an explosion of evolution since the 1950s due modern agricultural practices and cultivation.

For a striking example, look at the changes in chickens since the 1950s.

To be fair, humans have gone through similar visual change, but that's probably more to do with what we eat and how we live than genetics.
