Re: Does evolution have a goal?
Correct me if I'm wrong, but the process of evolution as we have observed seems to be resulting in ever more advanced species.
Will the universe someday observe a super human?
Over time, various DNA molecules have become longer and can code for more complex structures (organisms).
The young earth had relatively few long DNA molecules. The Earth today has more in comparison. There has been a progression along this line over time.
Putting aside all the subjective judgements of "direction" and "goal" and "advanced". It seems that there is a pattern over time of increased complexity of the DNA molecule (and perhaps complexity in general) as a result of evolution.
The question of Complexity is a difficult one, and one I have started threads on before. Some have argued that the collective bulk of living material is no more complex than at earlier times, and this is a difficult thing to measure, but it doesn't address the fact that there exist now, more complex living structures than once existed.
None of this means that there is a "goal" to evolution, any more than there is a goal to a crystal growing or a stone falling. However, a stone will fall 'down' for certain reasons, and evolution may produce complexity for certain reasons.
A similar pattern of increasing complexity exists in cosmology as well. The young Universe was a quark fog, but as it cooled, more complex structures formed, and as stars began to collapse and explode, more and more complex atoms formed, leading to more complex molecules and compounds and processes.
Some have argued that the notion of complexity itself is an ill defined state of affairs. But that's hard to support outside of a purely philosophical framework.
