As Merry Camhi of the National
Audubon Society points out "Unlike most bony fishes in which the survival
of millions of eggs and larvae are often largely dependent on environmental
variables, chondrichyans (sharks and rays)
exhibit a much closer relationship between the number of young produced
and the number of breeding adults." Kill a substantial proportion of adults,
and the population cannot be expected to be replaced.
"Take, for example, the Sandbar and
Scalloped Hammerhead shark, two species frequently caught in the Atlantic
and Gulf of Mexico fisheries. The sandbar takes 13-16 years to reach maturity
and then gives birth to 8-13 pups every other year. Female hammerheads
can take up to 15 years to reach maturity and then give birth to 12-14
pups. The Spiny Dogfish (shark) has a similarly long growth period to reproductive
maturity and produces 2-15 young every second year." ... 'Sharks Beware',
Scientist, November/December, 1999, Volume 87, page
The fact that the Hammerhead shark
can perceive very weak electromagnetic fields, an ability human beings
lack, makes this species so abundant and a tourist attraction around the
world. Like other sharks and rays,
hammerheads migrate extensively,
using their detection and navigational abilities to find prey buried out
of sight and also to guide their movements back and forth from their sea
mount homes to neighboring feeding grounds.
The Great White Shark has 'jelly filled'
canals (pores) on his snout in order for it to be able to detect bioelectric
impulses in the water. It can detect movement from great distances.
northern most caribou inhabiting the Arctic islands do not migrate south
for the winter, like the more southern ranging caribou. Paleontologists
believe this to be because the distance is too great and the energy costs
of traveling too high. Well, ok...but, why are the northern most ones able
to exist throughout the winter, when their milder climate cousins are urged
If you're tired of reading all this,
just think how little
we are covering of all the complex systems supporting life there are. What
intelligence must be possessed to put it all together.
The smartest chemist can't yet even
produce as effective AND safe a product as the complex system designed
in arctic fish and Black Widow spiders.
are flying mammals – the only ones! Bats are of their own order. They are
unique! Their wing consists of an arm that ends in a wrist with a thumb
and four separate fingers which are webbed with skin and form the ribs
of the wing.
A bird’s wing by contrast, possesses
a reduced number of 'finger' bones. By shaping their 'hands' they control
the shape of their wings. A muscle complex in the wings of all bats is
different from birds and all gliding mammals.
The vampire bat is the only mammal
whose entire diet consists of blood. They do not puncture the skin. The
bat painlessly shaves off a tiny sliver of skin and drinks the blood that
seeps from the wound. Its saliva contains an agent that stops the blood
from clotting before its finished feeding.
Studies with mitochondrial
DNA have shown that all bats are closely related, and separate from primates.
such a marvelous and complex manner mother bat resorbs
calcium from her bones into her blood and passes it to her growing offspring
Evolution would provide for stupid
minded people to swallow gobbledegook
like this: 'In time the bat 'sensed' a need to provide better nourishment
to her offspring in order to sponsor stronger specimens, ensuring continuance
of the species'.
The processes involved to accomplish
this are so intricate and interdependent that if they failed to simultaneously
function, and function perfectly the very first time, there would be no
Evolution doesn't address the short
time of pregnancy of the bat during which this sophisticated procedure
be able to have occurred. Perhaps this is because it is out of the realm
of time normally needed for evolution to attain believability for its obviously
shallow minded tenets.
Some bats have their young in the
fall season, yet fertilization is in spring. Bats can delay fertilization
for up to five months. Why not eight or ten? Fertilization can occur soon
after copulation (sex, the verb),
yet the development of the embryo
can be delayed for months. Bats control this? Wow! Evolution has never
accounted for the mechanism. These various strategies
increase chances food is available when the young are born. Gestation
period is from 50 to 120 days.
There are so many different habits
in so many different kinds of bats, many with opposite behavior patterns
to other bats. Some migrate 200 miles; others 1200 miles. Like birds, it's
a north/south migration. Bats migrate
when they can hibernate in winter
temperatures, which some do. Most bats eat insects, fruit, etc. Bats help
keep insects in check. they eat mosquitoes, but only a few. With all they
eat nightly, they end up eating the equivalent of about half their body
weight. In tropical areas carnivorous (flesh eating) bats eat other bats.
Some live 7 years and others 25 years. They disperse
plant seeds throughout tropical islands.

Bats:-A Natural History-by
"...all fossil bats, even the oldest, are clearly
fully developed bats and so they shed little light on the transition from
their terrestrial ancestor."
Bats in Question-by
Don E.Wilson, 1997, Smithsonian Institute Press, Washington D. C. "The
oldest known skeleton, supposedly 60 million years old, is a fully-formed
bat which apparently could echo-locate." ...UCMP-(University
of California Museum of Paleontology), Berkeley, 1999,-Chiroptera:-Fossil
Bats rely mostly on their hearing
in echo locating, and never developed pathways of vision common to other
Whales, Dolphins, sea lions and seals
also use echolocation.
How did the
bat persist, and how did it survive while it was awaiting evolution to
form its radar capabilities? Why would a bat produce its high pitched radar
system pulses, unless it also immediately had the ability to detect them?
Why do muscles we use to lift things counter balance as they do, enabling
us to safely raise objects of various weights? The musculature involves
arrangement, tensile strength, motion, etc. The integration of these evinces
a marvel of engineering design.-...continues
