Sure. And I see that in your replies. I'm excessively blunt, and I value bluntness in others. So you're fine.
New genes often occur by gene duplication:

Abstract
Gene duplication is an important mechanism for acquiring new genes and creating genetic novelty in organisms. Many new gene functions have evolved through gene duplication and it has contributed tremendously to the evolution of developmental programmes in various organisms. Gene duplication can result from unequal crossing over, retroposition or chromosomal (or genome) duplication. Understanding the mechanisms that generate duplicate gene copies and the subsequent dynamics among gene duplicates is vital because these investigations shed light on localized and genomewide aspects of evolutionary forces shaping intra-specific and inter-specific genome contents, evolutionary relationships, and interactions. Based on whole-genome analysis of Arabidopsis thaliana, there is compelling evidence that angiosperms underwent two whole-genome duplication events early during their evolutionary history. Recent studies have shown that these events were crucial for creation of many important developmental and regulatory genes found in extant angiosperm genomes. Recent studies also provide strong indications that even yeast (Saccharomyces cerevisiae), with its compact genome, is in fact an ancient tetraploid. Gene duplication can provide new genetic material for mutation, drift and selection to act upon, the result of which is specialized or new gene functions. Without gene duplication the plasticity of a genome or species in adapting to changing environments would be severely limited. Whether a duplicate is retained depends upon its function, its mode of duplication, (i.e. whether it was duplicated during a whole-genome duplication event), the species in which it occurs, and its expression rate. The exaptation of preexisting secondary functions is an important feature in gene evolution, just as it is in morphological evolution.

Yes. New Zealanders and Australians tend to be blunt as well.
Wow! I'm blinded by science. You know what you are talking about and I can't argue with what you have said, although some of your long words were the same as my doctor's when he gave me a diagnosis, and I told him that he was speaking in tongues and I would try those words in church next Sunday!
I am realising why I was banned for the ChristianForums site for three months. The staff there are mainly from the USA or the UK, and they may not understand the New Zealand direct way of expressing thoughts and opinions.
I heard a good example of this when an Australian had an exchange student staying with him and his wife, and they had a small baby. He asked the girl to nurse the baby while he went and did something else. She was horrified, so he told he he would nurse the baby himself. She was even more horrified. What he learned that the American meaning for 'nurse' is to breastfeed the baby! While the Australian meaning was to hold the child. When he was in the USA he told that story and a person said, "What do you say instead of nurse when your wife breastfeeds the baby?" He replied, "We say 'breastfeed' because that is what it is. We Australians say things as they are".
UK people are very polite in their language. They would say, "Wouldn't you like to consider having cornflakes for breakfast? While a German, meaning the same thing, would say, "Have cornflakes for breakfast!" It is because there are no polite words in German. It is not that they are being deliberately abrupt.
Compare:
"Actung! You vill close ze door because you verent born in ze tent!"
and
"I'm sorry, but would you mind closing the door, just to give the impression that one is not born in a tent."
That shows the difference between cultures.
I just thought I'd include that bit of information for interest and add a bit of lightness to our conversaton. :-)
