Acanthodes bronni: Humans evolved from a prehistoric SHARK from 300m years ago. By Eddie Wrenn Published: 17:15 GMT, 13 June 2012 | Updated: 09:01 GMT, 20 June 2012 Humans evolved from a prehistoric shark that roamed the seas more than 300 million years ago, say scientists.
The primitive fish named Acanthodes bronni was the common ancestor of all jawed vertebrates on Earth - including us, according to new research. A re-analysis of a braincase dating back 290 million years shows it was an early member of the modern gnathostomes - meaning 'jaw-mouths' that include tens of thousands of living vertebrates ranging from fish to birds, reptiles, mammals and humans. Acanthodes, a Greek word for 'spiny', existed before the split between the earliest sharks and the first bony fishes - the lineage that would eventually include human beings.

'King of Wasps' found in Indonesia: Two-and-a-half inch monster has jaws longer than its legs. By Rob Waugh Published: 14:53 GMT, 23 March 2012 | Updated: 19:44 GMT, 23 March 2012 A new species of wasp discovered on the Indonesian island Sulawesi is two-and-a-half inches long, and has jaws so vast that its discoverer admits, 'I don't know how it can walk.' Lynn Kimsey, professor of entomology at the University of California, Davis, says ‘Its jaws are so large that they wrap up either side of the head when closed.
When the jaws are open they are actually longer than the male’s front legs.' The male wasp has such enormous jaws that its discoverer admits, 'I don't know how it can walk' Kimsey discovered the warrior wasp on the Mekongga Mountains in southeastern Sulawesi. She says its enormous size and ferocity makes it like 'the Komodo Dragon of wasps'. ‘I’m going to name it Garuda, after the national symbol of Indonesia,’ Kimsey said. ‘The first time I saw the wasp I knew it was something really unusual,’ said Kimsey. ‘I had never seen anything like this species of Dalara.

But as this picture shows, great white sharks do not always get things right when moving in for the kill. A shocked group of tourists in False Bay, South Africa, were left amazed when they saw this 12ft shark emerge from the water to catch a seal. Incredible: Tourists in False Bay, South Africa, were left amazed when they saw this 12ft shark emerge from the water to catch a seal. But rather than carrying out a swift kill, the shark slightly misjudged its attack which resulted in the poor seal being finely balanced on the nose of the predator. The amazing scene was captured by South African wildlife photographer Chris Fallows near Seal Island, which is home to an estimated 64,000 seals and a group of great white sharks which hunt them.
