Before I get started, I should say that this is mostly taken from the memory of a lecture I watched about the singularity, with my own random thoughts and misperceptions added in.
$this->bbcode_second_pass_quote('Omnitir', 'T')hough if every single human were to evolve, then I guess we could get away with calling ourselves human, even though, technically, we have evolved and are therefore a new species. Of course, the fact that we evolved through technology rather than biology should be of no importance.
There is in fact no difference, most people think of evolution in terms of biology, but technology is merely another form of evolution, people think that because something was designed it's not a part of evolution, but design itself is the latest
step in evolution.
the first step was random emergence (may be getting that term wrong), after that you have single cell organisms that only made copies of themselves and only evolved through random mutation, a very long process, sexual reproduction is a much faster form of evolution, allowing species to change in generations by swapping genetic material with each other. Intelligence is the
next step in evolution, bringing even faster change.
Our heads are much larger than is needed for basic survival, no other mammal has as much trouble with childbirth as humans, and it's because of our massive noggins, full term human children are 'premature' compared with other mammals, and human mothers are much more likely to die from childbirth than other mammals.
why? because of Natural Selection, the other half of evolution that most people forget about, to most people when you ask them about evolution they will talk about Survival of the Fittest, this is half of the theory, the other half is Natural Selection, Natural Selection is responsible for the Peacock for example.
what is going on there is 'Displayed Weakness' (think i'm getting that term wrong), the Peacocks massive tail is a liability in survival terms, but it's a signal to the female that 'I'm such a badass I can haul this ridiculous thing around and still be alive'.
Stags operate on the same principle, hauling around massive head ornaments just to impress females.
Natural Selection for humans, is based on intelligence, we are a society driven species, completely reliant on others for the first several years of our lives (compare this to a foal that can stand within minutes of being born).
Our brains increased in size drastically for a couple hundred thousand years (ish), and levelled off about 50 thousand years ago, basically at the point where we are at the maximum amount of risk you can reasonably take as a species, if our heads were any bigger birth would be just too dangerous.
genetically, we haven't changed much in 50 thousand years, we have however gotten much smarter
without genetic changes, because of intelligence and language. We have evolved far beyond what is necessary in survival terms, and the reason for that is Natural Selection, followed by Intelligence and Language.
So, after sexual reproduction, we have design (language and intelilgence) as the next step of evolution, which includes lamposts but also includes things like genetic engineering (creating the possilibity/reality of genetic 'adjustments' that would take thousands of years or
never naturally), the Flynn Effect (increasing worldwide IQ's) etc.
To the universe there is not much difference between a tree, and a lampost, both are products of evolution. both are collections of atoms that are fantastically unlikely to happen spontaneously. The difference being that a lampost is even more unlikely than a tree, and a
bunny-human is even more unlikely than a lampost!, it would never happen naturally.
The next step after intelligence, is machine-assisted intelligence, now you think I'm talking about the singularity again but
haha! we have machine assisted intelligence right now, and you are using it!
It's estimated that being at a computer with an internet connection raises your IQ by at least 10 points, you have a much wider access to information than you by yourself have. which is what intelligence is all about.
Addtionally we of course have things like computer-aided design, without which we wouldn't have the computers we are using, or jets/battleships etc.
the possible next step, is either when the machines we design and create, start themselves designing their next versions, or when we merge with machines, giving a drastic intelligence increase and marrying the strengths of our pattern recognition and guessing with the strengths of machine intelligence.
Machines are already intelligent, not in the fuzzy 'self-aware' conception of it, but in the sense of practical measures such as math and recall, they perform on a much higher level than humans. the ability to do math is a standard measure of intelligence, and in that limited definition (and other areas) machines do well.
