Any way what the hell does this have to do with the two countries in question?
Eps ? Meh. [/B][/QUOTE]


This is exactly what I was thinking.

Evolution is not brought about by a need for change, it just happens.

As far as I'm concerned that is complete crap, if that was true why do we have an opposable thumb? You didn't think the need for it to hold basic tools had any effect on it becoming that way. I just find what you?re saying logically incorrect.

As for random, what I see when I look at organisms is not random. Why do plants have viocty "veins", (thingies, looks at Harlequin for right spelling) so they can grow bigger in the competition for sun light. This is an adaptation. So is the multicellular idea, the cells group together to have a better chance of surviving. There are just too many examples that we can see make it so plain that was your saying is very far fetched. Though I can agree that the chance for an organism to evolve is random (that?s why some die out) but I can?t accept that the adaptations they do evolve are random, I see them all as having a purpose. (Or most any way.)

Though considering you?re the biochemistry student you?re most likely right. So can you please explain what the heck you mean a bit better? Thanks.

Eps - Bleh. :P [/B][/QUOTE]

OK, I'll elaborate on exactly what I mean.

Let's say you have a load of bacteria, and then you decide to kill them all with some antibiotic. Ideally, they all die, but in practice a few sometimes survive because they happen to have a resistance to that antibiotic. That resistance wasn't there [i]because[/i] the antibiotic was present, but it helped the bacteria out in the long run. Hence the future generations replicated from those bacteria will carry the same resistance.

The same principle applies with higher organism evolution. The changes are absolutely random-- The plants have those viens, but there are probably a load of other ways- many of which may be more effective- of acheiving the same effect. The reason the plants have those veins is that they happened to evolve that way.

I know what you're taught in school, and at the time I was in school I'd have the same standpoint, but as you go higher into education, those teaching you have a tendency to tell you that everything you've already learned is nothing but a vague generalisation, or an earlier theory on what there's actually a lot more to.

The thing is, evolution is dependent on the envirionment only to select which slight changes are better than others. Humans have an opposable thumb because it was a random change which happened to be favoured by their surroundings- those without them didn't have the same capabilities and their genes gradually faded out through the generations.

So yes. I know that until a certain point people are generally told that evolution is all about animals responding to their surroundings with a slight change over time- but what it's really about is a series of random changes, which may or may not be favourable to the species. Characteritics that are favourable tend to be passed on, those that aren't favourable aren't passed on. The most severe example of an unfavourable characteristic is when the baby dies instantly (or never really lives) as a result of it. Obviously, that baby would never have a chance to have kids, so it's genes don't get passed on. It's kind of the same for evolution as a whole, but on a more gradual level.

If the world stops changing then it doesn't necessarily mean evolution would stop- but things would take a more random approach rather than being "selected" by the environment.

I am so tired of watching these silly conflicts everyday on the news, everyday there is a suicide bomber or an attack, bomb etc...EVERYDAY, When is it all going to end? When are we going to hear about interesting NEWs!

It'll end when humanity ends. It's gone on for centuries, and it will continue to.

Yo, Deus, let's get back on topic, shall we?

[color=red][size=1]Yo, Duo Max, let's let the moderators do the moderating, shall we?

[Guest cloricus]

Thanks for explaining that Deus. :P

Hehe Justin.

Well that's about all I wanted to say.

Eps - Confuzion!
