-Yay, here's my rant.
-Eh, what Daniel is talking about is ONE process of evolution but it's certainly not the best type of evolution. Plus removing chest hair characteristics would take ages, you'd have to eliminate every gene that associates with chest hair from the gene pool and doing so may lead to unwanted results like the lost of some spacial intelligence (I don't know about the latter part but you get the point).
-According to Daniel, artificial selective breeding is the way to go. I wouldn't say so since we've been doing that to dogs over many generations and breeds such as the pitbull are fail in terms of successful births; most of the time they need c-section because the babies' mouths are so huge that they can't leave their mother's womb. True there are successful artificial breeds out there, I don't deny that, but the point is everytime humans try to push for something new and promising there's always some sort of backfire. Those backfires could be a lot worse if we accidently direct evolution against nature, the total opposite of what evolution is for.
-So the best thing to do in my opinion is to not do anything artificial like make arranged marriages just for the sake of breeding a specific trait. It could work but then you must realize that method may devoid of any real love. Without love in the equation, the world will fall. And I'm not getting off topic either, it's been scientifically proven that people are attracted to others who are more genetically different than they are simply because it makes healthier babies. This also explains why incest is rare and avoided in practically every species.
-So what do I say in the end? Let's just let evolution do what it normally has done for the last several million years, it has brought us this far after all.

some of the sources were too vage and in some they wouldn't actually say anything that says how evolution works,
but simply a rant going on about that evolution is fact


I'm Christian but damn, you got pwned. Take Anthropology in college, it'll make sense. Plus, your post is very vague.

The basis of evolution is selection of parents

e.g. Selective breeding

All animal breeders have produced wierd and amazing results, by using selective breeding.
For instance, this extremely muscular cow. They do not have the technology to geneticly modify DNA.
They did it through selection of parents ( choosing the most muscular bulls/cows to breed with ).


I can create the effect of evolution too. If i had the power



The selective breeding you're talking about is still artificial, not exactly the best form of evolution. Evolution plays it's ace card when there are huge changes, like the Ice Age. It's meant to occur naturally according to the earth's changes, so humans could evolve into beings who can take in more radiation being that there's so much radiation around but probably not enough to be a new species since everything else is conpensated through technology.

Yes you do have the power of evolution, it's in your pants.

My new pick up line:

"Hey girl. You and I should evolve humankind."
I'd follow that up with a creepy wink and goofy smile.

Yea, and what's your point. I somehow doubt that we will see a come back of the joy division.

Selective breeding isn't the same as natural selection. Selective breeding only proves particular traits can be emphasized. But in the wild the organism best fit for its environment can still die.

selective breeding is NOT evolution

evolution is when the environment and all NATURAL surroundings are the deciding factor

humans choosing species to mate to breed a certain type is NOT evolution for there are no changes and it is not natural it is all done by a process

what?
evolution is supposed to be natural
animals evolve in order to adapt to their environment
selective breeding is man-contributed
muscular cows through selective breeding is genetic engineering - not evolution

Evolution=change in the genetics of a population from one generation to the next.

Selecitve breeding=allowing organisms with favorable traits to breed so that unfavorable genes are eliminated from the population, and so that favorable traits are expressed more frequently and prominently.

Elimination of unfavorable genes and increased frequency of favorable genes= change in the genome of a population= evolution.

Artificial selection is a type of evolutionary selection just like natural selection. The organisms with the traits that humans prefer are the ones best fit for surviving in their environment, which is around humans, so they are the ones who get to pass on their genes. The presence of other organisms, including humans, are just as much of an evolutionary factor as climate or resource availability.

First of all, selective breeding is evolution although man-controlled take cows for example they have been selectively bred to maximise milk production to the point that most milking cows now suffer pain if not milked frequently. This however ensures the milk demand is met. This however isn't to say we have it mastered, we can breed in one trait and accidentally breed out another or breed in a detrimental trait.

Secondly hate to break it to you but its true you can breed out a trait but you can't ensure its permanently removed as gene regression can occur, and the trait returns or it can re-evolve, its hard to keep beneficial traits down regardless of how much you dislike them and old traits can become beneficial again as climate and other factors change. Also as you'll read later the trait could seem bred out but could be dormant or just recesive. It's not easy, lol.

Thirdly all this talk of preventing stupid people breeding, is in its self retarded(proving that you shouldn't open your mouth unless you've done your research) and bordering on nazism(look it up, also go read 1984 by george orwell you really need to), Intelligence is hard to prove to be a genetic trait as brain size and level of function doesn't always dictate your level of intellect i.e. you can have the facilities to out think einstein but without the drive or dedication you can still be stupid, intelligence is generally considered a learned trait although genetics can mean that one person can be superior even if 2 people put in the same effort.
However, i would like to point out roughly how human breeding works, 50% of you is directly inherited from your mum and 50% is from your dad and NOT ALL traits are expressed in your parents but they may express themselves in you i.e. Ginger hair is a recessive trait 2 non ginger parents that are carriers however can give birth to a ginger child e.g. R = non-ginger, r = ginger. M = mother, F= father RR is non ginger, Rr is ginger carrier, rr is ginger
-----------------------M
F (For reference the diagram is a punnett square and can get much much bigger depending on how many genes you look at :P) sorry bout the M and F couldn't get them to stay where i wanted them

That is an example of recessive and dominant traits ie a recessive will NOT be expressed in the presence of the dominant gene but it can be carried in a family for generations.

Another type of gene expression is harder to explain the best example is a cat ever look at it with various colours and wonder why they have blotches of colour here and there? That's another type of gene expression the colours switch on and off in coat colour development leading to patches of diferent colour. There are many factors in selective breeding and other genetic practices that we have yet to discover genetics isn't mastered yet not even close. We've barely learned the ABC's of genetics and started experimenting with it to make words.

Another point for you stop 'stupid people breeding' people, there is a required amount of available genes in a species gene pool in order for them to continue to exist, Mankind will not breed to perfection because we need imperfection if everyone was the same in appearance and traits genetic diversity would be very low this would lead to inbreeding and eventually death for our species and others with low genetic diversity like cheetahs(the URL has some info on the cheetah thing) http://en.wikipedia.org/wiki/Genetic_diversity , thats not to say we won't evolve but we won't become supermen either. Evolution is generally slow, although there is theories of explosive evolution too there have been little to no explosive evolution periods in earths entire history.

You need to look at the bigger picture when talking about evolution, i hope this post is helpful to some of you, if you want to ask me anything feel free to PM me

Even though you can't completely breed out some traits, you can decrease their freqency to the point where it doesn't cause any damage to toss out the occasional organism who gets the negative trait, i.e the skinny cow. But that really only applies to businesses.

Nice post, but I doubt many will read it.

Thanx ks i actually study biology at uni, so i thought i'd just put some info out
