Ahh..Because Viruses are TOO highly evolved to be living organisms!!!
Think about it: What would be the last living creature if the apocalypse came?
Viruses!!! Why? Because they aren't alive to begin with!!! Makes complete sense 
Go Pyro!!! The dude with an IQ of 168!!!! |
But is it "living" if it dosnt reproduce? It replecates!
Bowser~IQ= one higher than pyrorecca! |

Is Evolution confined to living organisms alone?
What is "living" anyway?
What happens if I forget to zip my pants and walk into the women's toilet?

viruses are living becasue they can change and adapt to things that can be painful to them, they don't replicate themselves they infect and use other cells reproductive parts to replicate copies of themselves, if it can die then that means it was alive.

Well my biology txt book sayz they arnt living organisms and it gives a bunch of facts as to why, tho i cant be bothered to type it up! Just trut me, i'v done a year of advanced biology. |

| Humans aren't subject to natural selection anymore, since even retarded, crippled vegetables are able to reproduce. But we're still evolving, albeit artificially, with the advent of technology and science. For example, the worldwide IQ average is rising by 2 points every year, mostly due to society's rising demand for brain usage. |

ur forgetting that u need to have different genes, in order to have evolution. the mixing of blood (ie gene pool) will promote the selection for a new and advantageous trait that imparts fitness to the individual in the environment.
perhaps a million years from now, the genetic variability will become too small (which is what i think you're suggesting), and some virus will come and wipe off everyone due to our lack of defence

Exactly. I mean, at the moment we are surounded with machines etc. So many useful things like storing fat isn't needed anymore, because we dont suffer from starvation. But what if something happens to the machines which are in a way replacing oure natural adaptments? I guess we must evolve fast or human race stops existing. (this made me think also, what if machines are oure way to evolve further? .. )
In many sci-fi movies, for example Cataca, gentically manipulated men are born with perfect genes. But if humans are born in labs then women eventually dont need to give birth anymore. And in the end we have only one sex - shemale (it has bot X and Y cromosoms)

| Evolution is happening.....There is plenty of evidence that suggests its existence.......Like how viruses become immune to certain drugs all the time. |
Its called - virus becomes resistant. At the moment third generation antibiotics are being used because many sicknesses have gained resistance against drugs we use at the moment. I think virus isn't the best example but pyro has point there. |

I don't see how selection can take place. We are talking about humans here. Survival to a reproductive age is practically assured. Human evolution(If it happens at all) cannot be compared to the more conventional type of evolution....
Actually I'm saying the gene pool will grow larger but unique traits will be over powered by the more dominant genes and so will be suppressed....Unique traits just aren't selected for breeding in a human population. Even the laws of attraction and love obey genetic variation....We're more attracted to people who have greater genetic variation.....So if the gene that imparts greater survival skills is always being paired with another gene that is likely to be dominant over it, the genotype will not be expressed and the phenotype will be the "Normal" characteristics.
I guess it's a bit narrow-minded of me to use Non-continuous variation and not continuous variation......I'm a lazy ass
I love good debates. FUN!! LOL!!

Actually selection still does take place in human society. All heavily based on culture. It may seem like the popular western cultures have globalized the standard of female beauty, but different cultures used to have different standards for what beauty is. Even now, in some isolated cultures, they have very different views on female beauty. For example, we think of slim waist makes women more attractive. In some cultures, they'd view that as malnourished and weak woman and would prefer a larger waisted woman.
In some parts of Africa there are high percentage of sickle cell anemia disorder in population. This debilitating illness is in a way, "selected". Because, those deformed red blood cells are resistant to malaria parasites which requires healthy red blood cells in order to reproduce. (Malaria is very common in those parts of Africa.) Therefore a healthy person may be at a disadvantage in this case. Thus, this disorder isn't going to selected out of population.
Also, we have to remember that selection is not the only force in evolution. Events like bottleneck effect causes major change in populations.
Think about an example where few people migrates to an uninhabited island and starts living there for hundreds of years. There's a good chance that all their decendents are going to have some of unique features of the first settlers, such as some genetic disorder. So the whole population may share a common feature not found in other populations in rest of te world.
Evolution isn't an improvement or enhancement. It is simply an overall change in a population's genotypes and phenotypes.

I'll take that as a compliment...Hehe...Since most of what I know about Evolution is self-taught from books I read.

I'm just generalising.....There are always exceptions to every statement(Even this statement) and in a world populated be several billions of people there is bound to be some selection somewhere.
Most Modern human beings already have all basic necessities fulfilled. Food, air, water. shelter, safety. The next step in Human evolution will probably stem from Sexual Competition. African Countries who are generally more promiscuous will evolve at a faster rate than the rest of us. But it would have rather negligible effects.....I doubt there will be a splitting of human species. But natural selection doesn't account for all the evolution going on...There is another factor scientists have yet to discover....So Who knows really.....
