This blog was originally supposed to be an interesting article on Thanksgiving foods; specifically, a discussion about crops (i.e. squashes, onion, corn, carrots, parsnips, etc...) that traditionally accompany our Thursday turkey, as well as their weedy relatives.
However, I stumbled upon more thought-provoking article that I've chosen to share, instead.
The paper, 'Crops gone wild: evolution of weeds and invasives from domesticated ancestors', which was published in the journal 'Evolutionary Applications' (Norman C. Ellstrand (UC-Riverside) et al., 3:494-504) in 2010, can be accessed here.

Most important changes include:
