Interesting, Juan. I lack the intellectual capacity to understand most of the complex matters discussed here on interfaith, but am not lacking in imagination. Speciation is definitely one of the subjects my feeble mind would like to explore in more detail. Are we to look at the product of these sorts of unions as a shortcoming of the union, or perhaps as something new altogether? Shortcomings are often in the eyes of the beholder... Seen from one's comfortable perspective, or the perspective of orthodox science, one might consider that viewpoint as having no equal, let alone superior. But when at last it dawns on science that there is a bigger picture, then ooops! Everything we thought we knew goes out the window. Science must never lose it's imagination, it's desire for exploration, even in issues that go far and beyond it's known orthodoxy.
