Natural
Selection
Or
Genetic
Drift.
"Regressive evolution," or the reduction of traits over time, is the result of either natural selection
or genetic drift, according to a study on cavefish by researchers at New York University's Department of Biology, the
University of California at Berkeley's Department of Integrative Biology, and the Harvard Medical School. Previously,
scientists could not determine which forces contributed to regressive evolution in cave-adapted species, and many doubt
the role of natural selection in this process. Darwin himself, who famously questioned the role of natural selection in
eye loss in cave fishes, said, "As it is difficult to imagine that eyes, although useless, could be in any way injurious
to animals living in darkness, I attribute their loss wholly to disuse." Click

Australian

University
Fresh
Fossil
Evidence
Of Eye
Forerunner.
Ancient armoured fish fossils from Australia present some of the first definite fossil evidence of a
forerunner to the human eye, a scientist from The Australian National University says. Dr Gavin Young from the
Department of Earth and Marine Sciences at ANU has analysed fossilised remains of 400-million-year-old Devonian
placoderms jawed ancestors of modern fish whose bodies were protected by thick bony armour. The ancient limestone
reefs exposed around Lake Burrinjuck in New South Wales have produced exceptionally well preserved placoderm specimens
with the braincase intact, Dr Young said. Click

Nova
Scotia
Rare
two-toned
Lobster
Caught
off Nova
Scotia.
A Nova Scotia fisherman made a rare catch this week when he hauled up a two-toned lobster in St. Mary's
Bay. The lobster is divided into two colours straight down the middle of its back -- dull green on one side and bright
orange on the other. The fisherman who owns the trap the female lobster was caught in has named it Jay after his son,
who hauled it on board their boat on Jan. 8. Jay the lobster has been donated to the Bedford Institute of Oceanography
in Dartmouth, N.S., as an educational exhibit. "We got the call [Thursday] about the lobster," Doug Pezzack, a lobster
biologist with the institute said Friday. "It's a very uncommon catch. Every year, 20 to 30 million lobsters are trapped
[in the area] and we only hear about one or two of these a year." Pezzack said the fisherman had to get special
permission from the Department of Fisheries and Oceans to keep the lobster because of its small size. It measures just
83 millimeters from eye to tail, and weighs 0.36 kilograms. Typically, lobsters are a mishmash of greens and blues, but
Pezzack said sometimes strange lobsters like Jay are discovered, or even rarer ones that are bright blue, all orange or
albino. Pezzack thinks this particular lobster has a genetic mutation. Click

Unusual
British
Dinosaur
had
Crocodile
Skull.
An unusual British dinosaur has been shown to have a skull that functioned like a fish-eating crocodile,
despite looking like a dinosaur. It also possessed two huge hand claws, perhaps used as grappling hooks to lift fish
from the water. Dr Emily Rayfield at the University of Bristol used computer modelling techniques more commonly used
to discover how a car bonnet buckles during a crash to show that while Baryonyx was eating, its skull bent and
stretched in the same way as the skull of the Indian fish-eating gharial a crocodile with long, narrow jaws. Click

From Joshua from Okemos, Michigan,
Hello
Tom,
Nevin,
And
Fellow
Listeners,
I am
sorry
it
has
been
since
a
long
time
since
my
last
email.
We
have
been
very
busy
at
the
store
plus
I
was
out
of
commision
with
a
really
nasty
cold.
Last
Saturday
I
had
the
chance
to
go
to
Grand
Rapids
MI
to
hear
Karen
Randall
speak
at
two
meetings.
I
was
blown
away
by
her
vast
knowledge
of
aquatic
plants
and
aquascaping.
I
was
also
very
impressed
with
how
down
to
earth
she
is.
It
is
hard
to
find
a
true
expert
who
is
not
compeled
to
display
a
god
like
mentality.
Anyway,
If
you
ever
get
a
chance
to
hear
her
speak
go
for
it.
I
know
you
wont
be
dissapointed.
So
on
to
the
news....:)
Robert in New Jersey
calls and says his Altum Female Angel Fish and his Black
Male Angel have spawned and produced some wigglers, then
talks about how he got them to spawned.
Evan from Colorado says
he rearranged the live rock in his saltwater aquariums.
