 | 2007-JAN-14: USA: Federal government agnostic on age of Grand Canyon:
The organization "Public Employees for Environmental Responsibility"
(PEER) issued a news release on 2006-DEC-28 which has been covered on thousands
of web sites and made it into the Doonesbury comic strip for JAN-14. It
complains that park rangers at the Grand Canyon National Park are "... not permitted to give an official estimate of the geologic age
of its principal feature, due to pressure from Bush administration
appointees. Despite promising a prompt review of its approval for a book
claiming the Grand Canyon was created by Noah's flood rather than by
geologic forces, more than three years later no review has ever been
done and the book remains on sale at the park. ...
" 'In order to avoid offending religious fundamentalists, our National
Park Service is under orders to suspend its belief in geology,' stated
PEER Executive Director Jeff Ruch. 'It is disconcerting that the
official position of a national park as to the geologic age of the Grand
Canyon is "no comment".' " More

 | 2007-FEB-22: Chimp use spears for hunting: Anthropologists Jill
Pruetz of Iowa State University and Paco Bertolani from the University of
Cambridge in the UK documented 22 cases of chimps making spears to use in
hunting smaller primates. They removed live branches from trees and
sharpened one end with their teeth. Adolescent females used spears the most.
This discovery lends support to a theory that females may have played a role
in the evolution of tool technology among early humans. |
 | 2007-MAR: Mathematical model developed for galaxies: Scientists
at the W.M. Keck Observatory on the Big Island in Hawaii examined 544
galaxies and developed an equation that links their mass to the velocities
of their stars. Sandra Faber of the University of California, a co-author of
the report, said: "We were truly surprised at how well" the pattern
fits a wide variety of galaxy types including graceful spiral-shaped
galaxies, elliptical galaxies, and "train wrecks." The latter are believed
to have been caused by collisions of two galaxies.

 | 2007-MAR: Human evolution continues and is accelerating: The
traditional viewpoint suggests that humans evolved rapidly, and then
stabilized about 200,000 years ago when anatomically modern humans first
emerged. Gregory Cochran of the University of Utah in Salt Lake City,
UT and John Hawks of the University of Wisconsin-Madison have co-authored a
new study suggesting that human evolution has continued to the present time,
and even accelerated. They argue that change "is visible even in the last
tens of thousands of years." Back in the year 2000, anthropologist Jeffrey
McKee of Ohio State University predicted the accelerated evolution of humans
because as population grows, more opportunities are created for new positive
mutations. Also as the population expands, they move into new environmental
niches which will drive evolution in new directions. Anthropologist John
Kingston of Emory University in Atlanta GA suggests that evolution may be
speeding up because we are actively changing our own environment.

 | 2007-MAR: Role of early mammals after the extinction of the
dinosaurs: In the absence of detailed evidence, scientists had assumed
that when the dinosaurs went extinct 65 million years ago, the then existing
mammals immediately flourished. However, the MAR-29 issue of Nature
magazine contains the results of a study by the Imperial College London
and the Zoological Society of London. They found that it took ten
million years, until there was a sudden increase in the planet's
temperature, for the diversification of mammals to be established.
Andy Purvis of Imperial College said: |
"For the first 10 or 15 million years after the dinosaurs were wiped
out, present-day mammals kept a very low profile, while these other
types of mammals were running the show. It looks like a later bout of
‘global warming’ may have kick-started today’s diversity—not the death
of the dinosaurs. This discovery rewrites our understanding of how we
came to evolve on this planet, and the study as a whole gives a much
clearer picture than ever before as to our place in nature."

 | 2007-APR-13: Indications that birds evolved
from dinosaurs: Most biologists had concluded that dinosaurs were the
ancestors of birds because of the architecture of their bones. Now, new
evidence have linked the two in a more conclusive way. |
Researchers at the Harvard Medical School
and Beth Israel Deaconess Medical Center in Boston examined protein
found in 68 million-year old dinosaur bones. It had been believed that
protein in fossils was replaced with minerals by the time that the bones
were one million years old. This caused scientists to assume that all
evidence of protein was lost; they didn't look for such evidence until
recently.
Scientists have been able to extract proteins that formed part of the
dinosaur's collagen -- a part of the cartilage and other connective tissue.
The researchers found that the protein fragments seemed to most closely
matched amino acid sequences found in modern-day chickens. The evidence was
not absolutely conclusive, because they were unable to obtain a sufficient
number of sequences from the dinosaur protein. Their findings were published
in Science journal.
Mary Schweitzer of North Carolina State University and her team
published a paper in the same issue that provides additional evidence. They
found that extracts of dinosaur bone reacted with antibodies to chicken
collagen. 6
