Scientists Unveil Missing Link In Evolution

Scientists have unveiled a 47-million-year-old fossilised skeleton of a monkey hailed as the missing link in human evolution. The search for a direct connection between humans and the rest of the animal kingdom has taken 200 years - but it was presented to the world today at a special news conference in New York. The discovery of the 95%-complete 'lemur monkey' - dubbed Ida - is described by experts as the "eighth wonder of the world". They say its impact on the world of palaeontology will be "somewhat like an asteroid falling down to Earth".

Researchers say proof of this transitional species finally confirms Charles Darwin's theory of evolution, and the then radical, outlandish ideas he came up with during his time aboard the Beagle. Sir David Attenborough said Darwin "would have been thrilled" to have seen the fossil - and says it tells us who we are and where we came from. "This little creature is going to show us our connection with the rest of the mammals. This is the one that connects us directly with them," he said.

"Now people can say 'okay we are primates, show us the link'. The link they would have said up to now is missing - well it's no longer missing."

A team of the world's leading fossil experts, led by Professor Jorn Hurum, of Norway's National History Museum, have been secretly researching the 1ft 9in-tall young female monkey for the past two years. And now it has been transported to New York under high security, and unveiled to the world during the bicentenary of Darwin's birth. Later this month, it will be exhibited for one day only at the Natural History Museum in London before being returned to Oslo.

Fossil Sea Monster's Bite Makes T-Rex Look Feeble

OSLO (Reuters) – A giant fossil sea monster found in the Arctic and known as "Predator X" had a bite that would make T-Rex look feeble, scientists said Monday.

The 50 ft (15 meter) long Jurassic era marine reptile had a crushing 33,000 lbs (15 tonnes) per square inch bite force, the Natural History Museum of Oslo University said of the new find on the Norwegian Arctic archipelago of Svalbard.

"With a skull that's more than 10 feet long you'd expect the bite to be powerful but this is off the scale," said Joern Hurum, an associate professor of vertebrate paleontology at the museum who led the international excavation in 2008.

"It's much more powerful than T-Rex," he said of the pliosaur reptile that would have been a top marine predator. Tyrannosaurus Rex was a top land carnivore among dinosaurs.

The scientists reconstructed the predator's head and estimated the force by comparing it with the similarly-shaped jaws of alligators in a park in Florida.

"The calculation is one of the largest bite forces ever calculated for any creature," the Museum said of the bite, estimated with the help of evolutionary biologist Greg Erickson from Florida State University.

Predator X's bite was more than 10 times more powerful than any modern animal and four times the bite of a T-Rex, it said of the fossil, reckoned at 147 million years old. Alligators, crocodiles and sharks all now have fearsome bites.

The teeth of the pliosaur, belonging to a new species, were a foot (30 cms) long. The scientists reconstructed the reptile from a partial skull and 20,000 fragments of skeleton.

The pliosaur, estimated to have weighed 45 tonnes, was similar to but had more massive bones than another fossil sea monster found on Svalbard in 2007, also estimated at 50 feet long and the largest pliosaur to date.

"It's not complete enough to say it's really bigger than 15 meters," Hurum said of the new fossil.
Hurum had said of the first fossil pliosaur that it was big enough to chomp on a small car. He said the bite estimates for the latest fossil forced a rethink.

"This one is more like it could crush a Hummer," he said. referring to General Motors' large sport utility vehicle.

Among other findings were that the pliosaur had a small thin brain shaped like that of a great white shark, according to scans by Patrick Druckenmiller of the University of Alaska.

Pliosaurs preyed upon squid-like animals, fish, and other marine reptiles. Predator X had four huge flippers to propel itself along, perhaps using just two at cruising speeds and the others for a burst of speed.

Darwin's Theory of Evolution

Darwin's Theory of Evolution - The Premise

Darwin's Theory of Evolution is the widely held notion that all life is related and has descended from a common ancestor: the birds and the bananas, the fishes and the flowers -- all related. Darwin's general theory presumes the development of life from non-life and stresses a purely naturalistic (undirected) "descent with modification". That is, complex creatures evolve from more simplistic ancestors naturally over time. In a nutshell, as random genetic mutations occur within an organism's genetic code, the beneficial mutations are preserved because they aid survival -- a process known as "natural selection." These beneficial mutations are passed on to the next generation. Over time, beneficial mutations accumulate and the result is an entirely different organism (not just a variation of the original, but an entirely different creature).

Darwin's Theory of Evolution - Natural Selection

While Darwin's Theory of Evolution is a relatively young archetype, the evolutionary worldview itself is as old as antiquity. Ancient Greek philosophers such as Anaximander postulated the development of life from non-life and the evolutionary descent of man from animal. Charles Darwin simply brought something new to the old philosophy -- a plausible mechanism called "natural selection." Natural selection acts to preserve and accumulate minor advantageous genetic mutations. Suppose a member of a species developed a functional advantage (it grew wings and learned to fly). Its offspring would inherit that advantage and pass it on to their offspring. The inferior (disadvantaged) members of the same species would gradually die out, leaving only the superior (advantaged) members of the species. Natural selection is the preservation of a functional advantage that enables a species to compete better in the wild. Natural selection is the naturalistic equivalent to domestic breeding. Over the centuries, human breeders have produced dramatic changes in domestic animal populations by selecting individuals to breed. Breeders eliminate undesirable traits gradually over time. Similarly, natural selection eliminates inferior species gradually over time.

Darwin's Theory of Evolution - Slowly But Surely..

Darwin's Theory of Evolution is a slow gradual process. Darwin wrote, "…Natural selection acts only by taking advantage of slight successive variations; she can never take a great and sudden leap, but must advance by short and sure, though slow steps." [1] Thus, Darwin conceded that, "If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down." [2] Such a complex organ would be known as an "irreducibly complex system". An irreducibly complex system is one composed of multiple parts, all of which are necessary for the system to function. If even one part is missing, the entire system will fail to function. Every individual part is integral. [3] Thus, such a system could not have evolved slowly, piece by piece. The common mousetrap is an everyday non-biological example of irreducible complexity. It is composed of five basic parts: a catch (to hold the bait), a powerful spring, a thin rod called "the hammer," a holding bar to secure the hammer in place, and a platform to mount the trap. If any one of these parts is missing, the mechanism will not work. Each individual part is integral. The mousetrap is irreducibly complex. [4]

Darwin's Theory of Evolution - A Theory In Crisis

Darwin's Theory of Evolution is a theory in crisis in light of the tremendous advances we've made in molecular biology, biochemistry and genetics over the past fifty years. We now know that there are in fact tens of thousands of irreducibly complex systems on the cellular level. Specified complexity pervades the microscopic biological world. Molecular biologist Michael Denton wrote, "Although the tiniest bacterial cells are incredibly small, weighing less than 10-12 grams, each is in effect a veritable micro-miniaturized factory containing thousands of exquisitely designed pieces of intricate molecular machinery, made up altogether of one hundred thousand million atoms, far more complicated than any machinery built by man and absolutely without parallel in the non-living world." [5] And we don't need a microscope to observe irreducible complexity. The eye, the ear and the heart are all examples of irreducible complexity, though they were not recognized as such in Darwin's day. Nevertheless, Darwin confessed, "To suppose that the eye with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest degree." [6]
