[QUOTE="inyati13, post: 1000873, member: 17767"] robert, the reason I said you were going into the science of Speciation is not because I thought you were unclear. On the contrary, your first sentence is a concept that you would spend a charpter on in any text book on Speciation. I took Speciation in about 1974, the text book was written by Ernst Mayr who at the time was the authority on how species are formed by the mechanisms of genetics, natural selection, and evolution. It occurred to me that Breeders are as close to Biologist as anything except maybe zoo keepers. Their fundamental materials are biological units. They are employing the sciences of genetics in their breeding to arrive at the phenotype they seek. It is interesting to me to see the diverse points of view on what a phenotype should be and how your arrive at it. But that is what you would expect. Despite the tools we use, man is pursuing a phenotype that is, "arbitrary and capricious". There is no word of God that gives us an absolute truth as to what a phenotype should be. In fact, what we generally accept as "the standard" might turn out to be a failure. I see it in everyone's comments. There are plenty of skeptics and I have even received PMs expressing them. I don't think anyone is right or wrong. I think the cattleman is doing his job and I applaud people who think their own thoughts and pursue them. [/QUOTE]
