 Now, some people think that nature created flowers to please humans. Well, not necessarily. Flowers are older than humans. Flowers go back before the dinosaurs. And so it means that the colors of flowers were not really created for our benefit, but for the benefit of insects, which have lived on the planet Earth much longer than us. And insects see colors that we cannot. So therefore, when you see the colors of flowers, you're only looking at a tiny fragment.
