reptile sets speed record for dna change (disovery)

this lizard is often called a living fossil it is because the tuatara looks as if it hadn't changed in the 200 million years of that kind. but appearances can be quit deceiving.the tuatara is actually faster than its ancestored. this lizard 9,000 has developed to be 50% more quicker than the other ones. given the high rate of evolution, the stable morphology of the tuatara over ten of million years is very remarkable.

how mars got lopsided (discovery)

for more than 30 year astronomers have known that mars is lopsided. the southern highland covers about 2/3 of mars which is about 2 1/2 miles higher then the northern plains. but until now, whether disparity was causing an asteroid impact or a volcanic action on the surface of mars which has dispute. when this happened there was a huge scar on the northern half.the northern plains form an elliptical depression 6,600miles long and 4,000 miles wide and since there are crater people think that there was an widespread volcanism. the craters were formed about 4 billion years ago.

black holes birth baby stars (discovery)

at the center of the black hole there is a ultra massive amounts of young powerful stars which should not even be there. the young stars are living under a gravitational conditions that should not even permit the proses of the star formation. there were clouds that would plunge right to the black hole. the gravitational force would rip the clouds in to pieces the black hole can stay the same shape because it has its own temperature.

shark bites are the strongest bite on earth (discovery)

scientist have calculated the force of a great white shark bite.the great white shark is probably one of the most powerful shark in the ocean and out of all the extinct animal. a normal size of a great white shark is 8ft long and 530ib, one of the enormous great white shark is 21ft long and 7,300ib and one of the longest living shark which is able to open it mouth 35 degree wide and squeeze it prey with about 4,000 pounds of force.every one know that a great white shark can bite hard enough to kill any human . The great whites are able to kill any thing above water like a bird flying close to the water.

what is in a sperm whale head (science illustration)

The sperm whale has a oily wax in its head the oil is found in two separate organs. One of the organs is called a case it like this huge champer, the second is the junk it is this big junk of blubber very blubbery. The air passes through the phonic lip which will create a loud sound.All of the organ in a sperm whales head is the blow hole, phonic lip, sound, case, air sack and the junk. There are 300,000 sperm whales left there range is world wide. I think in the early 1900's there was a lot of people who would hunt the male sperm whale.

call of the wild dolphine communication (science illustration)

The bottlenose dolphins which is considered to be the toothed whale, they will spend most of there time in little groups called a pod. In a pod there will be about 15 or less dolphins. Different dolphins will run into each other and i think from there on will be a big pod. under water the dolphins have there own signature whistle and when the mother and its calf the mother may whistle continuously over and over again until the calf can identify the mother. Then they can mimic one another's signature. biologists have realized that one dophine says its signature and then another dolphine whistle an identical response. Dolphins can see the human skeleton and heart they take interest in a pregnant women because they see the kid in the woman. Dolphins are said to have helped people get to the shore and to scare sharks away.

violent birth of the stars (discovery)

Star birth can tell us were the atoms in our bodies came from and the why the universes look today.
