I wonder if male humans would lift their leg, and the females squat down along the hydrant. Guess we could have floppy ears as well. May be the up and coming fashion fad. Look at my Basset Hound Ears they are so Rad.

Looks like we'll need to keep our thumbs, though, to manipulate the scooper.

It may not be an indication of your overall intelligence, but the inaccurate communication of your points will leave too much room for alternate interpretation or just plain confusion to be able to discuss something lik this rationally.

Please show me a reputable source that says Europeans are on the top of the BIOLOGICAL evolutionary "pile". Making an assertion that Europeans are on the top with no proof makes the BURDEN of such proof lie on your shoulders, not ours.
Ah , I'm ever so greatful he's on the other side. It's not even worth a reply. I think he makes the other sides case though. LOL

It is curious. This is the 4th or 5th identical thread posted under various sections of the forum. guess he/she wanted reactions from a wide area of Joe/Jane public.

I'm not offended by anything said. First of all I'm not a Swede nor a creationist. Although my views differ radical from both sides of the discussion. Incredibly I've been labled, but not in this Science/Tech sub-forum a dumb a s s , prick , S O B delusional , stupid , idiot , left or right wing (I don't even vote period) and so on. Those responses usually have been when I've asked a question that could'nt be answered or I've actually given a lengthy complete answer.

In the end it does'nt really matter anyway.

I think in the future we will be able to created other sentient beings. Like a elephant as smart as a man is now. Make a dog that can talk and think, and live much longer than 15 to 20 years. We will be able to cure most diseases, and control bacteria and viruses much better. Understanding the DNA code and how to manipulate it is the holy grail of biological science in my opinion.

There's little question that we'll continue to use our minds to make new discoveries and advancements. But there's a lot more more involved in the process. Ninjahedge gave an excellent example of science being like an inverted onion - the deeper you go, the more layers you uncover. We're finding the same thing about the mind itself - there are many strange layers involved, and the deeper you look the more you can start wondering about the nature of reality itself. The point is that we can learn things about nature, and we can even tweak things a bit, but nature itself is extremely complex.

There might be a way around it, but at the present time, it looks like the only way a new species of human could be made would have to include the ability to pass on the genetic code through reproduction. If it's only applicable to the treatment of a single person, and it can't be passed on through reproduction, then all you have is an enhancement of a single person. That's not a bad thing, but it doesn't mean a new species of human.

In the process of evolution by natural selection, changes happen all the time. But those changes are ever so slight, almost unnoticable. And the process seems to be one change built on another over an incredibly long period of time. Creating a new species of human by means of genetic modification might also involve a process over hundreds of thousands of years. And there's still no way to know if it would result in a successful evolution that continues on or if it just would reach a dead end to its own eventual extinction. The point is that evolution is an extremely slwo and involved process. It doesn't involve just a few things. It involves an enormous number of variables, including probable outcomes. Had there been even the slightest differences in the past, we might not even be here, or we might be very different than we are.

Certainly mutations at the genetic level played a part in it, but adaption to environmental conditions (not just weather) probably had a role in it as well. Mutations enable adaption, and adaption enables further mutations. In my opinion, they probably work together. If a mutation occurs but is unable to adapt, then the mutation would have to change again until the organism can adapt or the organism will become extinct.

So the question is whether or not there may be shortcuts in the process, or whether it can be sped up or not. But even if there are ways, natural selection still takes over in the end. And that leads to another question: other than showing it could be done, would there be a real benefit to genetically create a new species of human? Perhaps natural selection is more efficient at it.

At the present time, and I suspect for a very long time to come in the future, it's probably more efficient using mechanical enhancements. For example, it's cheaper and more efficient to send robotic probes and rovers to explore the planets than it is to send humans. Granted there are things people can do that machines can't (at least at the present time), but for initial exploration, machines are the best solution in covering long distances. For humans, body parts that wear out are becoming more and more replaceable with artifical parts. But that doesn't change the species.

It's possible a new species could branch off from homo sapiens, but then that gets back to natural selection.

According to the theory of evolution yes, humans will evolve into something else eventually, but it will probably take tens-if not hundreds of thousands of years. Even with the tech, I doubt many people would really want to be made into sci-fi style cyborg clones and all that jazz, so we'll probably evolve the old fashioned way.

But if all humans evolve together into something else, that something else will still be what we humans are. That's not what the Neanderthals did---they just died out, and were replaced in their niche by a different species.

However, if there is selective DNA engineering, designed to send some humans down one evolutionary path, and some down another, then there will be divergent evolution into "something" and "something else".

There were lots of homo species living when fully modern humans made their appearance, like neanderthal, homo floresiensis and even homo erectus (which lived almost unchanged for at least a million years). Eventually they all died out, most likely because we out-competed them. But we all came from the same roots.
If we messed w/DNA and somehow managed to create new superhuman species that survived better than regular people, the same thing might happen again; they could eventually make regular humans extinct. More likely though we would all interbreed and converge again, keeping us all the same species.

Species won't normally diverge into two different species unless they are physically separated, and unless humans in the future colonize different planets and are permanently cut off from each other, we will all remain the same identifiable species in the end, because we all intermingle in the now globalized world. Maybe race will even dissapear in time if we remain permanently globalized. It would be very interesting to see where our kind goes in the next million years. Realistically speaking though, we are more likely to nuke the world within the next 50 year and make evolution start all over again with bacteria.
