THE CREATOR'S HANDIWORK: AMPHIBIANS AND REPTILES
The amphibians Include frogs, toads, and salamanders. The reptiles
include lizards, snakes, crocodiles, and turtles. There are astonishing
facts about these creatures which clearly prove they could not have been
formed by evolutionary processes.
FRESH FROZEN
Some
creatures survive the winter by hibernating. Others burrow deep into the
ground to avoid freezing temperatures. But there are others which
actually do freeze! The painted turtle of the northern U.S., can freeze
in the winter and still survive. It can be in water which freezes solid,
and as long as less than 54 percent of the water in its body freezes, it
will later thaw out and do just fine. As freezing nears, the blood sugar
levels in this turtle triples, and certain amino acids, which act as
antifreeze preparations, greatly increase in its body. In addition
glycerol, another antifreeze substance, triples.
MIDWIFE FROG
Unlike
most frogs, the female midwife frog lays her eggs on land close to
water. The male midwife frog takes the eggs as they are being laid by
the female- and twines the strings of eggs about its hind legs.
He then digs a hole in moist sand or soil, which he does very rapidly.
There he sits with the egg string, waiting patiently while the eggs
incubate.
Then, at a certain time, he knows to suddenly climb out of the hole and
jump into the water and begins swimming energetically. This breaks the
egg membranes, and tiny tadpoles scatter in all directions.
GECKO LIZARD
This
tiny lizard can walk across your smooth ceiling upside-down without
falling off. Scientists could not figure out how the little fellow
accomplished the task. Using optical microscopes up to 2,000 diameters
magnification, they found thousands of transverse lines running across
each of the four finger‑like toes on each foot. Well, that gave some
information, but it did not solve the problem.
Then the powerful scanning microscope was invented, and it was turned on the foot of the gecko lizard. A series of photographs were taken, each 35,000 diameters or more in magnification. They discovered that each of the "fingerprint" ridges on its toe--was filled with millions of short fibers or hairs; on the ends of each was a tiny suction cup!
This would provide immense sticking power too immense. The poor creature
could put its foot down on a smooth surface--and not be able to lift it
back up! But the lizard's foot is designed so that the toe joints bend
or curl up at the ends. In this way, the gecko lizard can bend up each
toe, and unstick them gradually without having to do it all at once.
It was estimated that one gecko lizard has at least 500 million suction
cups on his 16 toes How wondrously made are even the smallest of the
animal life forms.
Evolution could not enable the gecko lizard to walk on ceilings.
Remember that the next time you see a lizard walking on a wall.
SERPENT'S TONGUE
As its
forked tongue flickers in and out, the serpent is picking up small
particles from the air or ground and transferring them to Jacobson's
organ. This is a special structure shaped like a pair of pits in the
roof of the mouth, with a sensory organ lining similar to that in a nose, but much more accurate.
