This is the tail end of the last discussion in "The Origin of Specious Nonsense" thread, which due to it's size now needs to be *retired*. This thread is now the new home for such talk as previously was restricted to the now closed thread above. The post below seemed a good a place as any to make the transition.

Although I came late to it, this is a fascinating thread. I would say every misconception about evolution is contained within its pages, along with lots of sensible and valid argument. I have not read the entire thread but have sampled extensively as it meandered back and forth from the extremes of the "evolution proves there's no God" strong atheist worldview to the "God made everything all at once" creationist position. Both positions are absurd given how little we really know and how much our knowledge evolves over time.
If nothing else the thread is a caution to resist making too many claims for current science. Evolution as a theory is ongoing science, with complexity far beyond anything Darwin or Dawkins for that matter could have dreamed of. The complexity of evolutionary mechanisms is staggering and as we peel back the onion layers it gets virtually incomprehensible (sound like something familiar? the physical universe for example).
A shout out to the much maligned Mick Rock who has been entirely consistent as far as I can see on this thread. He has stuck to one basic tenet, that evolution by natural selection of variations that arise from random mutation of genes is far too simplistic to explain evolution of life on earth. I suspect Mick has arrived at this position from logical reasoning and intuition as he has never tried to defend it on a scientific basis.
Although it may be unpopular to say this, he is most likely correct as modern scientific research is suggesting. Anyone who is actually following the research would be aware of this rather than pandering to Darwinian and neo-Darwinian dogma.
The most recent research suggests there are four mechanisms involved in evolution:
1. Genetic or DNA based. This is reasonably well understood although we have a long way to go in terms of understanding how genes are regulated to build a complete organism from a zygote. Clearly any changes in DNA for whatever reason are passed on from generation to generation. However, random changes in DNA appear quite rare in nature, in fact what we are finding is that the genome has highly sophistocated protection mechanisms to protect from mutation.
2. Epigenetics. Changes in the chemistry within the genome that does not change the DNA sequence but has an impact on how genes are expressed. This is a relatively new field but research is suggesting that these changes that occur during the organisms lifetime may be passed on for multiple generations. This helps to explain rapid evolution in species which has been widely reported in the scientific literature and simply cannot be attributed to chance mutations. Lamarckism arisen from the ashes.
3. Behavioral (learning). Darwinian evolution does not address how organisms react to their environment, develop traits to respond to it and pass on these traits to their offspring. Anyone who looks at an ant hill will understand this point. The underlying mechanism here is not well understood yet, although it is clearly to do with neurological development.
4. Language. Perhaps the most interesting of all. This is the basis for group evolution or societal evolution and is likely the primary driver for the rapid evolution of the human brain over the past 10,000 years. Not much idea yet what mechanisms are involved here.
All four share one common trait, information transmission. It seems absolutely clear that organisms since the beginning of life on earth have adapted to their environments in ways that are inherited by future generations and there is nothing "undirected" or "purposeless" about the overall process. Nature contains complex creativity that we are just beginning to comprehend.
