Homology: A Bouquet of Broccoli
One wouldn't normally munch on a rosebud or snap off a dandelion flower for a
quick snack. But in fact, in terms of homologies, when you eat broccoli or
cauliflower, you are doing just that. Although not scented or suitable for
centerpieces, the green tips of broccoli and the white tips of cauliflower are
actually flowers. Through many generations of artificial selection, farmers modified
the bright yellow blooms of the wild mustard plant into the edible, vegetal plant
parts you'll find nestled next to the ranch dip on the hors d'oeuvre tray.
