>>13629843>1. There's no proof macroevolution exists. You can't turn a fly into a human.What about plants? Many plants have been selectively bred to become very different from what their wild versions are. Humans created an environment where differently fit plants from the same species survived and prospered.
Brassica oleracea is a species of plant. It is also known as wild cabbage. This one species of plant is all of the following: cabbage, broccoli, cauliflower, kale, Brussels sprouts, collard greens, Savoy cabbage, kohlrabi, and gai lan.
This obviously raises questions about what defines a species. Is a cabbage different from Brussels sprouts? We don't consider them to be different, but if a person had run into them a few hundred years ago they would consider them to be different species of plants.
