Some Interesting Prehistoric Stuff

I love to browse the Sci-Tech page (page 154) on BBC1’s Ceefax (teletext) service. There’s always a lot of interesting snippets culled from various sources such as the New Journal of Physics, Nature and Science magazines. My favourite areas of interest are astronomy and space exploration, and palaeontology, and here are a couple of palaeontology snippets from recent pages:

Apparently scientists in Germany, Switzerland and the US claim that they’ve found the point at which the African and Indian elephants split and diverged from a common ancestor. They compared genetic research done on both species and other research done on the extinct woolly mammoth and mastodon, and came to the conclusion that the split occurred 7.6 million years ago.

Another interesting snippet concerns the dinosaurs. Accepted theories state that when the dinosaurs first evolved, they swept all before them, and rendered the earlier, more primitive forms of reptiles (known as dinosauromorphs) quickly extinct. Apparently that’s considered now not to be the case, and both lived side by side for many millions of years.

Just a couple of interesting snippets from the pages of Sci-Tech. Go to Ceefax page 154, and git yerselves ejjicated a bit. 🙂
