Now, blu, are you there and paying attention? I don't want to have to ask you 8 times whether you understood and accept what I say, O.K?
Now you know how we get new species. Remember those fish? 100 years had passed, and we got one new species in that time. So the two species are separated, don't have any contact, and can't interbreed anyway. Imagine another 100 years, and by chance (just to illustrate) each one of those gives rise to another new species, so we've got four species in all. Imagine that 1000 years go by, and this happens a few times.
Couple of things result from that. First, you can see how it's a branching pattern, because every new species branches off very slowly and gradually from an already existing species, and another species can possibly branch off from that. If you drew it graphically, it would look kind of like this:
Do you see why? Please look at this picture and make sure you understand it. So at the bottom (the present) we have around 8 new species by this point.
Second, at this point, you might have one species that's 1" long, tan with yellowish speckles, eats microscopic plants, lays 100 gelatinous eggs, etc., and one that's 4" long, brown with a single tan stripe, eats tiny shrimp and snails, bears live young, etc. At some point the Biologists say again, "Hold the phone. These two creatures are two different to be in the same genus any more. [remember what a genus is? Let me know if you don't.] We're going to call this a new genus now, and we'll call it Forumus religia." So while you never get a new genus arising directly from an old, eventually by the exact same process, you get new genera as well as new species, all by exactly the same process.
DO YOU UNDERSTAND THIS PART?
