Chicken or an Egg ??? solved by science . . . . . . . .

onalRemember for an old question which is almost for a long time ago , we never know what the answer is  . . . .                             " what is the first exist ,  a chicken or an egg ?? " .

in a few past years , this question is still ambiguous to explaining  the truth answer .  But  now , we can smile for that question . Even it is a simple question , but is has a long journey to the scientist to get the truth answer for it. See this quote that i have been taken from ANTARA NEWS (INDONESIA) 

  

Scientists this week claimed to have solved the puzzle. The answer, they say, is chicken. As reported Mailonline, the researchers found that the formation of egg shell depends on a protein found only in chicken ovaries. That is, the egg can only exist if it was in the chicken.

"Protein called ovocledidin-17, or OC-17 - act as a catalyst to accelerate the development of the egg shell. "
Hard shell is important as a place for egg yolk and white. Scientists from the universities in Sheffield and Warwick use the super computer to download'zoom in 'the formation of the egg. Called Hector's computer revealed that the OC-17 is very important in initiating the early stages of crystallization or the creation of the shell. These proteins change the calcium carbonate into calcite crystals that form eggshells.Calcite crystals in a variety of bone and shell, but they are formed more quickly in the chicken. Poultry was able to produce six grams of egg shells every 24 hours.

Dr Colin Freeman, from the Department of Materials Engineering University of Sheffield, said: "During this time people thought that there is first an egg, but now we have scientific evidence showing that an earlier is the chicken actually exists."


Well , thanks for the scientist to solved this puzzle ,  at least we have more knowledge what and how it became and surely tell it true for the kids or another person which still never know the answer "What is the first exist , A chicken or an egg ??"

Orca hunting technique

Do you remember about "free willy " film ? When a fish jumped up above a young child . . . Yes . . It have a scientific name and it called "ORCA" , Orcinus Orca , precisely .

Orca is the biggest formed from dolphin family . The color of their body makes a big differences with dolphins . The colors are black , white and grey . Male orca can reach 5 - 9 m with 9.000 kg of weight. And they can live until 50 years. And for female orca can reach 5 - 8 m with 8.000 kg of weight and they can life until 80 years old.

Orca can find in anywhere , but the most is in a cold sea. They live in groups with small family. Orca likes to eat an animals with hot blood type , they eat much variouses of fish , squirrel family , and sometimes they eat sea birds .
Orca Patagon in Argentina has perfected their hunting in off shore. They throw away their body to the sand to catch up a walrus child who stay on the sea side ,eventhough it dangerous their life.



Orca uses sea canal in the deep blue sea on Punta Norte beach to the sandy mainland through two rocky area where the walrus are grow. Orca waiting for the walrus on the sea and watch them until it close to the sea margin. They use sonar to detect prey passing through in canal and then they slide straight to the beach. Orca will landing on the beach with a half of their body outside the water with eat a walrus .
With a victim on their mouth , orca will moving wild their head and body to follow wave which it can bring back to the sea.

Where is the longest cave in the world ?

Hiding behind the surge landscape in the midle-south of kentucky state , U.S.A, There is the longest cave in the world : Mammoth Cave . It called Mammoth is not from the name of an elephant who was lived in ice periode , but because of it have a big dimension . This cave have at least 365 mil (587 km ) subway line.

Mammoth cave is being formed in 10 million years ago , when the soluble lime rocks, remainder bottom of the old sea, scraped by rain and stream flow from the surface, the power of water scraped makes a big hole in lime rocks and created a caves and tunnels in Mammoth cave.

Since 1800, Mammoth cave have been visited by tourist and scientist . Mammoth National Park establish on 1941 when almost of 53.000 acre (21.448 hectare) be separate for cave conservation and support environment. This National Park have many of flora and fauna , and a little bit of them are threatened to be extinctly, including five types of fish that only found in this cave .
