it's the same with 4 fingers tho: eventually the people of the past (5-fingers) would die out, and the 4-fingers would be seen as superior because they were able to survive while the 5-fingers couldn't-- so it's still progress-- but yeah, i guess change = evolution at the baser level- logic always confuses things |
Polydactyly (increase in no. of fingers/ toes) is present in the human population today. Its a autosomal (not sex-linked) dominant condition, but isnt usually present due to incomplete penetrance. This means there are other genes compensating (or masking) the condition (or could be environmental conditions). So, although it is existant, its rarity and not being advantageous to humans means it wont really be a prevalent condition that would lead to speciation.
Having said that, you could look at it in this way. Say you have a group of monkeys that live on the ground. Now, a mutation arises which gives an extra digit (or some other useful appendage), and this digit gives extra ability for the monkey having the mutation to climb up the tree. If this mutation survives and is able to be passed on to some of the offspring, they to can climb the tree. Now there is a different food source available for the mutant finger monkeys, and so they decide to live up there. But the population living on the ground is still quite happy there, as they have the original condtions which still sustain them. Eventually there will be 2 different species of monkeys, as they wont interbreed and will diverge individually. The selection pressures for each group is now also different, as they live in different places and eat different food. Either one could a) diverge again or b) go extinct. Its not that original group will go extinct simply because a new mutation arrvied. This is why we have so many different species on earth. Evolution is more about the change rather than a linear succession of a "better" genotype.
anyway, this is a very simplified explanation, im meant to be studying. 
finally, heheheheheh monkeys.

I realise all that (not about the monkeys, i just wanted to keep the thread clean(ish), and i also think monkeys are nothing to be laughed at ) -- I simply didn't explain it because i assumed you knew, and it would appear you do 
I guess i'm wondering whether the new species wouldn't compete, or actively drive the old one to extinction-- if there was a shortage and it came to a point where the 2 tribes would be forced to fight (overpopulation creating lack of resources perhaps- whatever), then the monkeys who had adapted a new finger, making them not only able to roam the ground as well as the original monkeys, but also mine the depths of the trees (irony of phrase intended (for no reason)) in a superior way to the groundlings, then wouldn't that be seen as the treebies being superior because of the evolutionary process?
Pretty much i think that as soon as we're thinking about something, we're placing a judgement on it (the problem with objectivity), so tho the CHANGE of getting an extra finger isn't necessarily positive or negative, the outcomes always will be, as soon as we see them-- for this reason, i'm saying evolution implies improvement: tho, it's not conscious: an anomalie isn't evolution: evolution implies the change within a GROUP (race, culture, etc), not just the freak accident-- the freak accident turns into something permanent within a group... that's my uneducated belief about evolution anyway 
also: the fingers are an arbitrary analogy: no need to give me the lecture about recessive and dominant genes and physical anomalies etc
after writing that, i now find monkeys funny, and will laugh with you about them: hahahahahahaha!! "stupid monkey!" 
edit: so, for music: you'd be saying the music you USED to listen to was crap, if you said you're tastes had EVOLVED, since you no longer listen to it...
