BALTIMORE — Dinosaurs are
the most misunderstood creatures in
history, according to a Johns Hop
kins University specialist.
Paleobiologist Robert Bakker said
the popular notion is wrong that the
prehistoric predators were cold
blooded animals who over-ate them
selves into extinction.
Bakker has used modern scientific
tools to demonstrate that the di
nosaur’s use of body energy and its

bone structure are identical to
warm-blooded creatures such as
mammals and birds.
His studies into the predator-prey
ratio of dinosaurs demonstrate that
like all warm-blooded animals, di
nosaurs used only a small portion of
their food intake for body cell repro
duction. The majority of the food was
used for energy production to keep
warm and move.
The low energy-efficiency rate, a
persuasive argument that dinosaurs

were warm-blooded creatures, cor
roborates other studies in the last ten
years that the bone structure of di
nosaurs is identical to warm-blooded
animals.
Bakker said the dinosaurs became
extinct because they were too
specialized and couldn’t cope with
changing environmental conditions.
“The big, successful animals were
killed off in the weather changes of
the Earth,” said Bakker. “The di
nosaur went extinct because it didn’t

replace itself, as the weather killed
them off. ”
Mountain-building and sea
falling, which happens all over the
world constantly, limit the formation
of new species and the most highly
evolved, delicate species are the
most vulnerable.”
The dinosaurs didn’t grow too big
for themselves, or kill each other offi
or get too dumb to eat, or too weak to
move, as is popularly believed.”
Bakker also said the pooular myths
that dinosaurs were replacea by
superior creatures called mammals,
including man, is inaccurate.
“Actually, dinosaurs and mam
mals started about the same time but
the dinosaurs grew so much larger
and stronger faster,” said Bakker.
Bakker disagrees with Charles
Darwin’s ideas about the survival of
the fittest as far as dinosaurs are con
cerned.
Bakker said Darwin, who wrote in
the mid-1850’s, did not have many .
facts about dinosaurs at his disposal
when he formulated his theories of
evolution.
“As a result, Darwin’s theories on
the survival of the fittest are actually
short-term theories because of the
limited facts he had to deal with. The
long-term survival of species gives
you a very different pattern of life
and death. The most successful ani
mals for a short-term, like the di
nosaurs, are the most vulnerable
long-term,” said Bakker.
Bakker pointed to the alligator as
an example of a species that has re
mained the same for thousands of
years and is not very vulnerable to
environmental changes.
The alligator, a cold-blooded crea
ture, efficiently uses the majority of
its food intake for cell growth rather
than internal energy production.
Administrators
seminar set
for July 17
About 30 of the newest adminis
trators in higher education are com
ing to Texas A&M University July 17
to attend the 11th annual academic
administration summer seminar, a
leadership program designed to
familiarize them with the new terri
tory and sharpen decision-making
skills.
The opening address will be
Monday at 9 a.m. on third floor of
Rudder Tower.
During the first two of the day
long sessions, the new adminis
trators — from directors and de

A&M department
needs volunteers
for smoker study
Texas A&M University re
searchers are seeking some pack-a-
day cigarette smokers for continua
tion of an experiment that began in
March.
Smokers will be reimbursed for
the cigarettes they buy during the
study. The researchers are looking
for people who have been smoking a
pack or more of cigarettes a day for
several years.
Volunteers will monitor their own
smoking habits and be asked various
questions.
Interested persons should contact
the Texas A&M Psychology De
partment (845-2581) and leave their
name and telephone number. Dr.
Larry Christensen or Doug Ris will
contact them.
