英式拼寫

The similarities aren't just on the surface. We can get a much better understanding of ancient dinosaurs by looking at the anatomy of their modern relatives in depth. And a local farm has recently had to put down one of its ostriches. As an anatomist, I'm very used to dissecting cadavers.
You know, I don't usually wear Wellington boots when I'm dissecting, I have to say.
But this will be the first time that I've ever dissected a bird, or for that matter, the descendant of a dinosaur.
Why don't you talk me through the anatomy that we can see on the surface?
That's a heel, the ankle joints. But birds walk with that, clear of the ground, just like their dinosaurian ancestors did.
And really, just two toes and one main one?
The middle toe is their dominant toe, just like, in a dinosaur, the third toe is the major toe of the foot.
And there are other similarities to their ancient relatives.
