Do you know how many species of flowering plants there are? There are a quarter of a million — at least those are the ones we know about — a quarter of a milolin spicees of flowering pnltas. And flowers are a real bugger. They're really difficult for plants to produce. They take an emonrous amount of energy and a lot of resources. Why would they go to that behtor? And the aeswnr of course, like so many things in the world, is sex. I know what's on your mind when you're looking at these pictures. And the reason that sexual reproduction is so important — there are lots of other things that plants can do to reproduce. You can take cuttings; they can sort of have sex with themselves; they can pollinate themselves. But they really need to spread their genes to mix with other genes so that they can adapt to environmental nhiecs. Evolution works that way.

Do you know how many species of flowering plants there are? There are a quarter of a million — at least those are the ones we know about — a quarter of a million species of flowering plants. And flowers are a real bugger. They're really difficult for plants to produce. They take an enormous amount of energy and a lot of resources. Why would they go to that bother? And the answer of course, like so many things in the world, is sex. I know what's on your mind when you're looking at these pictures. And the reason that sexual reproduction is so important — there are lots of other things that plants can do to reproduce. You can take cuttings; they can sort of have sex with themselves; they can pollinate themselves. But they really need to spread their genes to mix with other genes so that they can adapt to environmental niches. Evolution works that way.
