Hawking Says Humans Have Entered a New Stage of Evolution 398
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.'"

Richard Dawkins, an evolutionary biologist of some note, coined the term to describe the ideas that people create, that reproduce in much the same way genes do.
This came from his earlier ideas of a "selfish gene [slashdot.org]" to postulate that genes existed to propagate themselves, which helped to describe a lot of aspects of evolutionary development, from altruism to various kinds of suicidal behavior. In other words, it isn't the lifeform itself that is important in the reproductive cycle, so much as the information they pass along.

1. Evolution has a goal.
It doesn't. We are not going to transcend or become ultimate beings. No. It just adapts critters to their environment. What's neat is that critters adapt to each other, together. Think about that, and ecosystems, and all that web of life stuff for a while and it's pretty neat.
2. Evolution is critter-centric.
We are simply carriers for genese. Evolution is gene centric. Most of your genes are useless to you. Stuff that is stupid at a critter level can make perfect sense at a gene level. Those little bastards are using us, and don't care about us at all, as long as we breed.
3. Survival of the fittest.
It's survival of the breediest, not necessarily of the fittest.
4. Evolution works through mutation.
Errrrgghh... I disagree with Stephen Hawking. Ok, mutation helps, but you know what? Evolution doesn't need it. Most mutations result in a f*kup, not something useful. Evolution just needs seperate populations and/or environments. Eventually populations diverge and become more suited to their environments.

Stephen Jay Gould told an anecdote about Richard Feynman excitedly announcing that he had discovered new principles of evolution. On inspection they turned out to be either well known findings or well known fallacies. Basically he was largely ignorant of the literature in the field. It says more about physicists than about evolution that he would deem himself qualified to wade into the fray with such minimal preparation.
It is not surprising that Stephen Hawking, another great physicist, similarly feels empowered to speculate about evolution without apparently having read Richard Dawkin's popular works. Others have mentioned memes, but Dawkin's notion of the extended phenotype might be even more pertinent. Hawkings appears to be taking the notion of the meme to the extreme of thinking that species evolution is now relying on actual gene analogues outside our physical corpus. Rather, our genes remain internal, but their somatic expression is external to ourselves.

No, but, the human condition seems to provide us with incredible potential in a diverse set of skills, but only enough capacity to develop a subset of that potential - if you become handicapped in one area, and you don't get despondent / depressed / suicidal, your drive to excel gets channeled into other areas, developing them beyond normal levels, and the fact that you are handicapped seems to "free up additional capacity" for the non-handicapped skills.

Most other languages are similarly imperative, if not downright derived from C (functional languages, while at least as old, never really caught on much). Operating systems still basically work the same way: they allow separate processes with isolated memory, separate users, restricted access to hardware by programs, preemptive multitasking, etc. Even GUIs aren't that new, since the WIMP interface was invented by PARC in the 70s.
What's new is all the high-level stuff done with it: having an internet that not only connects universities, but is accessible by everyone from their home or their mobile phone. Buying stuff on the internet, communicating with each other on Facebook, etc. The thing that's changed is who uses this technology, and what they use it for.

Actually, browsers have evolved a lot in the last 15 years.

For instance, look at Google Maps, or other AJAX apps. That's not static data, it's basically a way of running an application remotely. IMO, the whole HTTP legacy of web browsers is holding them back. The entire way interactive web pages are written now seems like a giant kludge, when for many things it seems like it'd be simpler to just write an app in C++ or Java or whatever, run it on the remote server, and display it remotely on the user's computer.

Mod my parent up. This is -precisely- true. The idea that we test a hypothesis and refine it based on experimental outcomes is utter BS. In all but the most -basic- of processes, there simply is no way to account for all possible results of testing a system; this is further compounded in my field, where an 'in vitro' experiment may yield different results than one 'in vivo'. To make matters worse, those 'in vitro' experiments may in fact yield different results in /different cell types/, given all other conditions being precisely the same.
Without going into too much detail, the real nature of science is that we already have a fairly good idea of what we -want- to happen before we begin testing. I may have a vague theory about the experiments will come out, but more often than not we end up writing the theory to fit the facts around the time the data is published, in such a way that it fits the data we've collected, even though that final theory may not have any relation to the initial expectations.
Some of this is also attributable to the funding system (at least in the US). Submission of a grant (money to do experiments) requires that you already have (preliminary) information, and a fairly tight and detailed set of theories to explain how what you propose to do will result in a conclusion, as well as what those conclusions will be. Essentially, you need to present some data in order to get funding to obtain data. Give too much preliminary research, and you won't have enough theory and interesting suggestions to get funding, but if you don't have enough research done (how you do this without money is a nice conundrum), you won't get funding.
In practice, this often means researchers with no active funding will dust off old unpublished work, and write theories around it, in order to talk the NIH into paying out money so real work can get done (since once you're funded, you can really do whatever research you want -- especially if we're not talking about a renewable grant).
So it's really a messed up system all around, but the scientific method as you know it has virtually no role in it either way.

Einstein fits perfectly with the scientific method. Both relativity and the photoelectric effect came from trying to solve known problems, based on observations that had been made. His theories were then tested (I suppose you could argue that in some sense, testing wasn't required, in that it was already proven from the observed data - I'm reminded of Einstein's reply of "Then I would feel sorry for the good Lord", when asked what if the experiment failed to support relativity. But we cannot always be so sure).
Newton similarly followed the scientific method when he came up with laws of motion, and a theory of gravitation, to explain observed facts. The progress he made was a fundamental part of the scientific method. His dabbling on alchemy and the occult was not so scientific, however - yet would you suggest that these somehow contributed to science and technology?
Socrates was a philosopher - but he himself came up with the Socratic Method [wikipedia.org], which I would argue is the sort of rational approach that later lead to methods such as the scientific method.
I think you are misunderstanding what the scientific method is. It's not "let's tinker around randomly and hope we find something through trial and error" as you imply - it's precisely the application of intelligence to observation that you describe, followed up with testing to make sure we are right. Hypotheses are not randomly made up, they must still fit the observed data, and theories must provide a model to explain the observed data.
