00:16And the name of this missing link is Titalik rosei.
00:20It means large, shallow water fish in the Nunavut language of northern Canada.
00:25The fossilised bones of Titalik show just how much it is a missing link between fish and animals.
00:31It had scales and fins like a fish, but its bones are very similar to ours of our bodies today.
00:37This is the shoulder bone, and you can see the socket where the arm fitted in.
00:42This, although it's short and stubby, is the humerus, the bone of the upper arm here.
00:48These two are the radius and ulna, the two bones of the lower arm.
00:52There are wrist bones here, but instead of fingers, because it not yet evolved properly,
00:57there are rays like the fins of a fish.
01:00It's one of those fossils that shows us a stage where we've acquired some of the features of a major group,
01:07but not all of them.
01:08So, in a sense, it's equivalent to that proto-bird called Archaeopteryx,
01:14which has got some features of reptiles. It's got a long tail, it's got teeth and so on.
01:20But it's also got feathers and wings, so it's got bird features as well.
01:24So, it's that kind of combination of characters.
01:28This is one of the most beautiful parts of Archaeopteryx,
01:31it's got a good thing.
01:32It's got a good thing.
01:33It's got to be a floating stick, so it's got a good thing.
01:35By the way, it's got a little bit of a compound in the cascade to go.
01:37Now, be sure to go.
01:38I'm going to ask you a different part of that.
01:39I don't have to know.
01:40So, let's give a little bit of an example of that,
01:42but I just like to ask you a different story.
01:43From what?
01:44See you then?
01:45I'm going to ask you today.
01:46My list of the first things we have,
01:47I was to go,
01:48and you cannot wait and you're going to know,
01:50I'm going to want to go.
01:52I'm going to hear what you do.
01:53I'm going to see.
