Not Your Puritans' Turkey
Alexis Madrigal applauds science for super-sizing your turkey dinner:
The traditional Thanksgiving dinner reflects the enormous amount of change that foods and the food systems that produce them have undergone, particularly over the last 50 years. Nearly all varieties of crops have experienced large genetic changes as big agriculture companies hacked their DNA to provide greater hardiness and greater yields. The average pig, turkey, cow and chicken have gotten larger at an astounding rate, and they grow with unprecedented speed. A modern turkey can mature to a given weight at twice the pace of its predecessors.
In comparison with old-school agriculture or single-gene genetic modification, these changes border on breathtaking. Imagine your children reaching full maturity at 10 years old.
