Inbreeding Possible Factor in Deaths of Darwin's Children

I found this article on Yahoo News Science. This article is about Darwin's children who died, possible from ultimately inbreeding.

Of course inbreeding is immoral in today's world, but not long ago marring ones cousin was accepted. As knowledge and technology grew so did our understanding of why its not a good idea to "keep it in the family."

I thought this article was interesting because it gave a little bit of Darwin's background that I previously did not know. Although icky, its still interesting.

It is a proven fact that animals as well as humans switch it up a bit to genetically be superior to unwanted traits or disease. To be more adaptable. For example: say Jews are the only race that carry a certain disease. Jews typically marry other Jews so they are keeping this so called disease in their bloodlines. If a Jew was to marry an Native American Indian then their children would have a chance of not having the disease. Its makes the genetics stronger when you mix it up. We do this with animals, breed out the desire traits breed in the unwanted. AND PLEASE BY ANY MEANS DON'T TAKE OFFENSE BY ME USING JEWS AND NATIVE AMERICAN INDIANS AS EXAMPLES. You never know, I could be Jewish or Native American.

My conclusion; you think Darwin would have caught on to this and maybe given his more of a chance by having a stronger genetic lineage. Nothing against his wife and children though, its just weird how he was supposed to be a scientist and he that many children pass.
