Tuatara - The Oldest Life on New Zealand

The Tuatara are called "living dinosaurs" since they roamed around along with dinosaurs aeons ago! Lizards and snakes are its closest relatives, however the Tuatara belongs to a different class of reptiles.
The word 'tuatara' is Maori for "peaks on the back". The Tuatara has a Third Eye! This eye is visible in young ones in a few months it gets covered with scales. This eye absorbs UV rays when it is young and it absorbs Vitamin D through it.

Due to its slow breeding cycle it is now soon becoming extinct.
It stayed on the New Zealand for all these aeons undisturbed however the dogs, rats, deers brought by man to this land has caused a great declination in the populations of these living fossils!!

An internet history of the internet

Well today I decided to do a little scientific history, and so here is my simple and fairly brief history of the internet.

Enjoy

From theoretical to practical research:

The internet first began to be seriously researched for the Defense Advanced Research Projects Agency (DARPA), a US military project, in the 1960's. Prior to this some concepts had been explored but no practical implementations were tried.

Around this same period researchers at a number of universties also began to explore the theoretical and practical necessities that would underlie such network.

In 1969, the renamed Advanced Research Projects Agency (ARPA) contracted BBN to set up ARPANET, which was two connect four major university computers. By 1970 more computers had been added and over the following years many, many computers were connected to this network.

The 1970's and 1980's and significant advances:

In the 1970's a number of advances made the internet more sophisticated. During this period ARPANET introudce email and the TCP/IP architecture was developed. This was much more sophisticated than the previous protocol.

During this period other networks as such as Usenet, NSFNet and BITNET were implemented, but I will not go into detail on that here, unless I get a request from readers. Suffice to say these developments broadened the scope of wide area networks.

The other major developments in the 1980's were over the ability to search and navigate around sites and databases and in this period a number of different solutions were attempted.

CERN, the World Wide Web and commercialism:

CERN, or the European Laboratory for Particle Physics, developed a protocol that distributed information and this soon became the world wide web. This protocol used hypertext, which is pretty much the link system that is available on the internet today. Soon graphical browsers follow, making this concept more practical.

In the early 90's the internet also began to first be used for commercial usage, whereas before its reliance on government systems meant that it was used mainly for education and research. In 1992 the first commercial servers opened allowing users to subscribe to the internet.

At this point our modern internet began and the rest...

...is history, but history that we are all a little more aquainted with.

I hope some people out there enjoy/find useful my scientific history, something I've never tried before, all my other articles being a little more traditional.
