If the basis of all life , diseases etc is now believed to be the " genetic pool " . that there are inactive genes whose combination could not survive enviromental demands there by were not lost but are still part of the genetic pool . it is then possible given the right conditions to activate these genes to produce a different product from the current product( animals/humans etc

Who factored in the time concept to validate evolution ? Does the discovery of inert genetic pool where possible combination are possible with the right activation agents not overtaken this thinking.

Genetics is much more complicated that most believe. We have a large number of genes that appear to have switches that allow them to change function. This has an advantage in that viable mutations occur more frequently than just by chance.

The rate of evolution depends on the time between generations. Bacteria and virus which have very high reproductive rates evolve very quickly (MRSA). Birds ,say finches, reproduce every year with a brood of about 4 to 6 so they evolve much more rapidly than large complex creatures such as humans. Hence Darwin's finches could have adapted in less than 100,000 years.

Humans are evolving slowly - we can see that we have become taller over the few thousand years - this is due to part to diet but it is still evolution, although not totally Darwinian.

So going back to the question. Individual mutations occur in the population all the time - but it takes many generations for selective evolution (Darwinian) to distribute an advantageous mutation throughout the population,

It takes millions of years for any significant change to take place in a species. The "inert genes" in the gene pool are just parts of the DNA that is repeated...it really serves no purpose. The only genes that will partake in evolution are the ones that are active right now. Spontaneous mutation and sexual selection are the two main driving forces behind evolution...if traits produced in these ways are favored by natural selection then they will become prevalent and evolution will be taking place. To witness evolution in one's lifetime is a fool's dream....except for microbes that reproduce so quickly that they do change faster than many other forms of life.

"Evolution" does not take millions of years. Some degree of evolution takes place in even a relatively short timespan. But accumulation of evolutionary change to the point where an entirely different species emerges takes quite a long time.

Darwin's finches did not differentiate in a human lifetime. They had probably been on their respective islands for at least a few hundred thousand years.

The hidden genes you are talking about would have to be prevalent and exist within a culture and environment where these adaptations had a direct affect on the likeliness of procreation. What you are talking about is possible but very hard to get started. Theoretically it is possible.

See some of my other answers related to evolution for a more in depth view.

What about Darwins finches...natural selection among them could be seen in a relatively short time period...yes one's lifetime..not millions of years.

Nah, not millions of years, I watched that movie in an hour and a half (fast forwarded alot cos it sucked in places) David Duchovny was good in it though

It was a crap question on the god boards, and it's still a crap question on here.

No.
