"Whatever
the ancestor of birds was, it must have had five fingers, not the
three-fingered hand of theropod dinosaurs. Scientists agree
that dinosaurs developed 'hands' with digits one, two and three --
which are the same as the thumb, index and middle fingers of
humans -- because digits four and five remain as vestiges or tiny
bumps on early dinosaur skeletons. Apparently many dinosaurs
developed very specialized, almost unique 'hands' for grasping and
raking. Our studies of ostrich embryos, however, showed
conclusively that in birds, only digits two, three and four, which
correspond to the human index, middle and ring fingers, develop,
and we have pictures to prove it.
"This creates a new problem
for those who insist that dinosaurs were ancestors of modern
birds. How can a bird hand, for example, with digits two,
three and four evolve from a dinosaur hand that has only digits
one, two and three? That would be almost impossible."
So are the words of Dr. Alan Feduccia, professor and former
chair of biology at the
University of North Carolina at Chapel Hill. He and Dr.
Julie Nowicki opened a series of live ostrich eggs at various
stages of development and found what they believe to be proof that
birds could not have descended from dinosaurs.
According to Feduccia, who has long
been a strong critic of the belief that dinosaurs gave rise to
birds, "There are insurmountable problems with that
theory. Beyond what we have just reported, there is the time
problem in that superficially bird-like dinosaurs occurred some 25
million to 80 million years after the earliest known bird, which
is 150 million years old."
If one views a chicken skeleton and a dinosaur skeleton
through binoculars they appear similar, but close and detailed
examination reveals many differences, Feduccia said. Theropod
dinosaurs, for example, had curved, serrated teeth, but the
earliest birds had straight, unserrated peg-like teeth. They also
had a different method of tooth implantation and replacement.
The theory continues to wane, and it just might become the
scientific community to give it up as nothing more than fairytale.

Mammoth Attraction At Wildlife Park

According to The Time of London,
Japanese scientists are planning to use tissue from the legs and
testicles of a dead mammoth to clone the extinct creature and
display it at an Ice Age wildlife park in Siberia. Sounds
crazy, doesn't it? Welcome to the 21st century.
The wooly mammoth, believed by
mainstream science to have become extinct roughly 10,000 years
ago, could be brought back by using a technique which involves
impregnating an Indian elephant - its closest genetic relative -
with mammoth sperm and then repeating the procedure with its
offspring. The result? 88% mammoth in 50 years,
according to the report.
Although methods of DNA extraction
have improved over the years, complete strands of DNA from
mammoths are hard to come by. An interesting fact,
especially considering that there are believed to be around ten
million mammoths buried in the permafrost in Siberia.
Because of the sparse population in the region, however, only
around one hundred specimens have been recovered.
Those behind the planned park are
already populating the site in north-east Siberia with other
species from the Ice Age in anticipation of the mammoth's arrival.
One thing's for certain . . . if they actually manage to pull it
off, it'll be Jurassic Park brought to life, and will
become an enormous world attraction unlike any other.
We'll just have to wait and see.


People Dumped Into Shark Tank

In
a recent freak incident that would frighten the daylights out of
anybody, a platform at the Aquarium of the Americas unexpectedly
collapsed, dumping 10 people straight into a tank teeming with
sharks. The accident happened while members of the aquarium were
on an after-hours behind-the-scenes tour.
According
to aquarium spokeswoman Melissa Lee, the platform they were
standing on is used by keepers to feed the sharks and is not
usually open to the general public. The steel footbridge in
the Gulf of Mexico exhibit allows visitors to peer down into a
400,000 gallon tank home to everything from a few dozen nurse and
sand tiger sharks to turtles, schools of redfish and stingrays.
"It
just cracked. We held onto the bars and swam to the sides,"
said Erin Rooney, 14, who was on the catwalk with her family when
it collapsed. Meanwhile, Dan Rooney, her father, was
frantically searching for his 2-year-old grandchild. "I
was just praying none of the sharks got agitated from all of the
splashing and everything. I mean, they got sharks in there
bigger than me," he said. To his relief, he soon
saw someone hand the toddler to another person on the stable part
of the catwalk.
"I've
been told they took off and went to the other side of the
exhibit," said
Lee. She went on to boast that staffers at the aquarium are
trained to deal with emergencies like this one, and reacted
quickly to the chaotic scene, pulling people from the waters using
nearby flotation devices.
Staffers
or no staffers, what a horrifying experience.
