How have we changed animals and plants?

                      Most of the farmed animals and crops that we use today are extremely different from their wild ancestors. Wild wheat is only a large form of grass, while maize produced small, hard kernels instead of the juicy  cobs we like to eat today.

                    The wild boar is also very different from the friendly pigs we see on modern day farms. Cattle were once long-legged, lean and dangerous to approach — unlike today’s slow, placid animals.

                     All dogs, however, are still exactly the same species despite the many differences in their shape and size, In 12,000 years of constant breeding, humans have still not succeeded in producing a new species of dog, in other words, one that cannot breed with its ancient ancestors. Modern dogs are still able to breed successfully with wild wolves and dingoes.
