Human Evolution Progress

Postby Nitro » Tue Jan 11, 2011 9:03 pm

So I would like to know what there is to know about our species' evolutive development. Darwin's theory and other theories and hypothesis as well. If possible, make it elaborate and thoughtful subjects. And for those that are really acquianted with this subject I'd like to know the stages of evolution i.e. post in this template:
Stage 1: From xxxx-yyyy year (bc or ad)
Organism or cellular state that is thought to be ancestor of our current organism.
Stage 2: From xxxx-yyyy year (bc or ad)
Organism or cellular state that is derived from before mentioned organism or cellular state.
.
.
.
I hope I've been clear enough about my request. Don't worry though if you're unsure or can't understand anything feel free to ask for further explanation. Cheers and thanks for help and understanding

Cis or trans? That's what matters.

The title of this discission has a problem that is very common in discussions of the process of evolution. The word progress. It implies progress toward a goal. Evolution has no goal. It will be very hard to understand this process if you insist on thinking in terms of intent.
Evolution is like a bunch of people driving cars by looking only at where they have been. Almost everyone crashes but a few are left to marvel at the long series of lucky terns they made. Hindsight only, No foresight.

Haha nice comparision with blindfolded driving. But anyway I wasn't asking about the rules or ongoing progress of evolution I am interested in what we know about our kind's past evolution for instance how we evolved from H.Erectus to H.Sapiens etc. So I'm interested in details that are known in our past not about the ultimate goal or cause of evolution. Thanks gents and ladies

The transition of our species from Homo erectus was very, very recent. I think you probably want to go back at least 10 million years to get a better perspective of where we came from. H. erectus was still kicking until around 1.3 mya.
A belief that is held in carefully nurtured ignorance of the alternative is hardly a belief to be taken seriously. -Richard Dawkins
