Hawking Says Humans Have Entered a New Stage of Evolution

movesguy sends us to The Daily Galaxy for comments by Stephen Hawking about how humans are evolving in a different way than any species before us. Quoting: "'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. 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.'"

Re:What's his point?

Well, first of all, humans are still evolving. I understand Hawking's point, but he's understating one aspect of our species to overstate the other.

I'll take his point, but I'll say none of this just began with literacy. The change in our evolution, if you can call it that, started with culture, and culture started a lot earlier than books, a lot earlier, in fact, than humans. Our closest relatives, the higher primates, show, to one degree or another, those abilities too.
