Hawking: Humans Entered New Stage of Evolution
Hawking: Humans Entered New Stage of Evolution
Stephen Hawking, the British theoretical physicist, says the human race has entered a new phase of evolution. He published this premise on his Facebook page and in a treatise called “Life in the Universe.” It's been in every science magazine and has been hashed over by believers and non-believers ever since...
The Internet has reacted and is a buzz with a lively discussion on human evolution and how differently we’ve evolved compared to other known species on earth.
Quite a bit different from the reception Galileo's scientific discovery received. The Italian physicist, mathematician, astronomer and philosopher came up with a different twist on an old belief and was denounced for declaring that earth was not the center of the Universe. He was warned by the Catholic Church to abandon his belief and was later tried by the Inquisition for publishing Dialogue Concerning the Two Chief World Systems, published in 1632. He spent the rest of his life under house arrest.
In the 1600’s the populace residing in villages and towns were illiterate. Books were read by wealthy families and members of the Church. Consequently the overall learning curve was nil for most people.
Hawking, the author of the best-selling book "A Brief History of Time," has intentionally tried to make difficult concepts in physics more accessible to the public.
And that is the jist of Hawking’s contention: that we are more than the sum total of our genes; we are what we read. Hawking maps our human progression from ten thousand years ago as an internal record phase transmitted through our DNA.
He says we are more than just our genes because we can’t discount the external record of other long lasting forms of storage, like the knowledge obtained from external sources, as contributing to our evolution, i.e the web, books, movies, etc..
"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," Hawking said.
The knowledge we have accumulated over the last ten thousand years is scant, Hawking points out, compared to the last three hundred, this he says is what sets the human race apart.
"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.
Hawking points out that in the 18th century it was possible to read all the books written. Today it would take 15,000 years to read all the books in the British National Library. By that time many more books would be written.
Hawking says we have entered into a “self designed evolution” in which we will have the capability of changing our DNA. At first changes will happen to single genes that control diseases like cystic fibrosis, and muscular dystrophy. Genes involved with intelligence are controlled by a larger number of genes which will be harder to identify. But, Hawking believes when they are identified both intelligence and behaviors, like aggression, can be modified.
This undoubtedly opens up an entire new area of disagreement between those who are against genetic modification, which makes this a political discussion as well as a scientific one.
