Humans Have Entered a New Stage of Evolution - Stephen Hawking

At first, evolution proceeded by natural selection, from random mutations. This Darwinian phase, lasted about three and a half billion years, and produced us, beings who developed language, to exchange information.
But what distinguishes us from our cave man ancestors is the knowledge that we have accumulated over the last ten thousand years, and particularly, Hawking points out, over the last three hundred.
"I think it is legitimate to take a broader view, and include externally transmitted information, as well as DNA, in the evolution of the human race," Hawking said.
In the last ten thousand years the human species has been in what Hawking calls, "an external transmission phase," where the internal record of information, handed down to succeeding generations in DNA, has not changed significantly. "But the external record, in books, and other long lasting forms of storage," Hawking says, "has grown enormously. Some people would use the term, evolution, only for the internally transmitted genetic material, and would object to it being applied to information handed down externally. But I think that is too narrow a view. We are more than just our genes."
Introduction and Conclusion can cause the biggest problems for your research paper at college or university. You will be surprised, but the research part is not the most difficult one for a lot of students. The biggest problems they face when writing an Introduction and Conclusion. They don't know what can be included and what can't be included in these parts, while keeping a healthy balance between an introduction, body, and conclusion in terms of word count. Read more
Given the individuality and uniqueness of every person, some things in life have to be unified. White collars are to dress in the classic style to work, while pupils wear school uniform on a daily basis. This allows for consistency and accuracy in their respective institutions just like the formatting does in writing. For clear and digestible expression of ideas, essays follow a certain structure, consist of particular elements, and have a special layout. Read more
Bike ride is the most elementary form of transport. In earlier days, it was the first human powered vehicle that later transformed the face of automation. The first bicycle appeared around 400 years ago. Slowly innovation and technology shaped the rudimentary bicycle into the modern day road bike that we are so accustomed to see. Read more
