    This is a bit misleading. You only need to treat the first generation of 2n watermelon with colchicine (which inhibits the movement of chromosomes during metaphase) to produce a 4n watermelon. Once you have a 4n watermelon, subsequent generations do not require colchicine treatment.



  • There’s likely some cases of convergent evolution, but I’m not sure this is settled for all trees.

    I’d suspect that at least some trees with last common ancestors that are shrubs have re-enabled genes that enable the tree phenotype rather than independently evolving the tree phenotype.

    But still really cool (and maybe turns on exactly how much evolution your consider needs to happen before it’s convergent evolution.)
