Unscramble the Blue Letters

So, let's go to Lake Turkana, which is one such lake basin in the very north of our country, Kenya. And if you look north here, there's a big rveir that flwos into the lake that's been carrying sediment and preserving the remains of the animals that lived there. Fossil sites run up and down both lengths of that lake basin, which represents some 20,000 sqaure miles. That's a huge job that we've got on our hadns. Two million years ago at Lake Turkana, Homo erectus, one of our human ancestors, actually lived in this region. You can see some of the major fssoil sites that we've been working in the nrtoh. But, esnlsatleiy, two million years ago, Homo erectus, up in the far right corner, lived alongside three other species of human ancestor. And here is a skull of a Homo erectus, which I just puleld off the shelf there. (luhtegar)

So, let's go to Lake Turkana, which is one such lake basin in the very north of our country, Kenya. And if you look north here, there's a big river that flows into the lake that's been carrying sediment and preserving the remains of the animals that lived there. Fossil sites run up and down both lengths of that lake basin, which represents some 20,000 square miles. That's a huge job that we've got on our hands. Two million years ago at Lake Turkana, Homo erectus, one of our human ancestors, actually lived in this region. You can see some of the major fossil sites that we've been working in the north. But, essentially, two million years ago, Homo erectus, up in the far right corner, lived alongside three other species of human ancestor. And here is a skull of a Homo erectus, which I just pulled off the shelf there. (Laughter)
