Definition RANDOM:- lacking any definite plan or order or purpose; governed by or depending on chance; "a random choice"Quote from: RD on 04/05/2010 22:34:34There was/is a reason for all the various forms of life : natural selection.So we both agree it is not RANDOM

Complexity is not proof of design ... http://en.wikipedia.org/wiki/The_Blind_Watchmaker
What is a Complex System?It's a revolution because working with complex systems goes against traditional science practice. Until now, scientists have spent a lot of time breaking things down into ever smaller component parts – known as reductionism – to understand how each part works in isolation of other parts, only to find that this does not help to understand how the whole system works together...............Although there are a wide variety of systems that are complex, they all have two elements in common. They all exhibit emergence and self organisation.

Are you suggesting self organization is proof of intelligence or an intelligent designer ?.Crystals self-organise but they are not intelligent. http://en.wikipedia.org/wiki/Crystallization#Crystallization_in_natureComputer automata self-organise but they are not intelligent,(their complex stable patterns emerge from elements repeatedly following very simple rules).http://en.wikipedia.org/wiki/Cellular_automaton
Truthfully we all have limited ability to see how evolution works but it doesn't happen over vast periods of time, like we were taught at school. I doubt that anything is truely random, its just that we haven't found the answers yet.Evolution depends on environment, time and networking, (The ability to be influenced or not by whats around.). Yes even crystals network to grow.How evolution knows to depend on nature time and networking is the question.
My opinion is that it is not scientific to think "it just happens".DNA networks with RNA to form life. How does it know to network? What compels it to do it?What compels them to network and form life? Obviously we just haven't found the answers yet.

And what's so wrong in accepting that sometimes things happen without a reason?
I agree with BenV here, I think lots of random things happen all the time.

Now we're talking about modern evolution.........
I think free will is extremely important, and free will provides a certain degree of random inherent in everything, IMHO.
"When scientists observe animals responding differently even to the same external stimuli, they attribute this variability to random errors in a complex brain." Using a combination of automated behavior recording and sophisticated mathematical analyses, the international team of researchers showed for the first time that such variability cannot be due to simple random events but is generated spontaneously and non-randomly by the brain. These results caught computer scientist and lead author Alexander Maye from the University of Hamburg by surprise:
Echo - we're not saying that evolution is random, but that mutation, one of the sources for variation that evolution can act upon, is.
Random mutation is one aspect of non-random evolution,

Protein coding genes of humans and chimpanzees are about 99 percent the same so therefore it is how the genes are regulated, turned on and off that makes us different. Quote from: BenV on 07/05/2010 08:53:47Random mutation is one aspect of non-random evolution, What type of Zen is this?We get Cosmos out of chaos?Random mutation just does not happen, why is science trying to prove "Random Mutation"?

Science isn't trying to prove random mutation, as it's just a fact that mutations occur at random throughout the genome during cell divisions. There's no getting away from the fact that random mutation is one source of variation on which evolution can act.
...the supposedly random shuffling of large chunks of DNA that frequently lead to cancer -- aren't so random after all...
Why Our Peripheral Vision May Not Be as Random as We Think
A pseudorandom number generator (PRNG), also known as a deterministic random bit generator (DRBG)[1], is an algorithm for generating a sequence of numbers that approximates the properties of random numbers. The sequence is not truly random in that it is completely determined by a relatively small set of initial values, called the PRNG's state.
I'm not sure what you think this has to do with DFTD, but they don't "know" that mating earlier will help. The disease must be altering their population structure in some way, and this means they are mating earlier.Does anyone know the 'normal' mating patterns for Tasmanian devils? Is it a hareem structure? Do the males fight for mating access?

I don't think that's quite right.Humans and chimpanzees are very similar in very many respects. I think the small differences between our genomes account for the small differences between chimpanzees and humans.
1. The chimpanzee and human genomes are strikingly similar and encode very similar proteins. The DNA sequence that can be directly compared between the two genomes is almost 99 percent identical. When DNA insertions and deletions are taken into account, humans and chimpanzees still share 96 percent sequence identity.Biologically, DNA is the common language of every living thing. By opening up the cells of any living thing - bacteria, plants, moulds or ourselves - we find DNA controlling every activity. A close look at DNA shows that humans are remarkably similar to the rest of the living world - sharing about 98% of our DNA with chimpanzees.While the DNA of almost all organisms is distinct in its fine detail, the overall structure of the DNA found in every living organism is the same.However each species has its own characteristics and among humans only identical twins share the same DNA.Even the DNA of plants is similar to that of humans. We share 60% of our DNA with a banana.
