Ancestors

Where do we come from ???

• Some 55 million to 65 million years ago ,the first primates appeared.
• The were ancestral  to all living primates including monkeys,apes & humans.  

  The evolution of Human Begins.

          

       Bipedal locomotion is a defining future of the hominids.They had small ape like skulls,slashing front teeth & mark sexual dimorphism.These bipedal hominids lived in East Africa.These hominids & some others who may have lived Eastern & Southern  Africa are generally classified in the genus Australopithecus. 
                 1.Australopithecus 
                 2.Homo Habilis
                 3.Homo Erectus
                 4.Neanderthals
                 5. Homo Sapiens
            Australopithecus;

Australopithecus is the first defined hominids.3 Million years ago they lived in much of Africa.
 The skeletal remains of a femal hominid Austhalopithecus found in Tanzania in 1974 and dated at about 3million years ago.

    Homo Habilies ;         
Homo Habilies inhabited parts of Su-Ssiharan Africa about 2-1.5 billion years ago.Homo Habilies was a early tool user and called as Handy man.

      

















Homo Erectus;
Homo Erectus evolved very shortly after Homo Habilies probably about 1.8 million years ago.Homo Erectus were firts found Java so the more familiaras "Java man." And also they were first fire users

.

  Neanderthal;

Neanderthal emaged emaged in 1500-3000 years ago.They were about 5-6 feet tall,with heavy bonces,large browse and brain was bit  larger thav us.(1350cc)

    

 

   

 Homo Sapiens;

Homo Sapien have bieen found in many part of the old world in Africa,Asia,Australia as well as Europe.The latin meeting "Wise man" brain capacity everaging about 1350cc hight forehead small teeth and jaw,defined chini construation and use of tools,and ability to use symbols.

Information Technology...



 What is Information Technology????


In the 1960s and 1970s, the term information technology (IT) was a little known phrase that was used by those who worked in places like banks and hospitals to describe the processes they used to store information. With the paradigm shift to computing technology and "paperless" workplaces, information technology has come to be a household phrase. It defines an industry that uses computers, networking, software programming, and other equipment and processes to store, process, retrieve, transmit, and protect information.

John Logie Baird, though little recognized in the US, was perhaps the most remarkable inventor in the early history of television. In a period of scarcely three years from 1924 to 1927, he invented the first successful mechanical-electric television system, infrared television

Computer
In 1837, Charles Babbage, a British professor of mathematics described his idea for the Analytical Engine, the first stored-program mechanical computer. The Analytical Engine was designed to be powered by a steam engine and was to use Punched Cards, which was used to program mechanical looms at the time.

                      1.Silicate solid crust
                      2.A highly mantle
                      3.A liquid outer core
                      4.Solid inner core
                     

As well as earth consist with 4 sphere
    1.Lithosphere
    2.Hydrosphere
    3.Atmosphere
    4.Biosphere

• Continents & Ocean consider as "Lithosphere".
• Atmosphere is the huge blanket of gasses that cycles the entire earth.
• The hydrosphere is the liquid components of the earth.
• Earth is the only planet on which life exist.It consist of mainly 3components Lithosphere,Atmosphere,Hydrosphere & Biosphere.Which is called as Biosphere                          .

Earth in Solar System...

                     Earth as one of planet..          

• Earth is the one of planet in Solar System.
• A well as earth is the one & only plant have lives.

What is this Solar System???

         

       Our solar system consist with an average star we call the sun & it have nine planets Mercury,Venus,Earth,Mars,Jupiter,Saturn,Uranus, Neptune & Pluto.It includes ; the satellites of the planets; numerous comets,asteroids & meteoroids.
