And how would you categorize current theories of evolution of species quantitative or qualitative?
How about genetic selection, quantitative or qualitative?
How is cross breeding between different species quantitative when a single gene is qualitative? I think your distinction is non-existent.
You flatter yourself. And be careful when you quote part of someone's sentence, without ellipsis, in a way that changes or obscures the intended meaning. Perhaps you did not get the intended meaning.
And how would you categorize current theories of evolution of species quantitative or qualitative?
I wouldn't. It's a nonsense question.
How about genetic selection, quantitative or qualitative?
A selection may be made for either a quality such as agility or a quantitative measurement such as size. So?
How is cross breeding between different species quantitative when a single gene is qualitative?
More nonsense. Cross breeding between species, which, by the way, results in infertile offspring, occurs rarely in nature. It occurs more often in man's domain, an example being a mule. The difference in occurence of cross breeding between nature's domain and man's domain, (an artificial reductionist difference) is quantitative as "frequentness" may be measured as a quantity.
