"Plus wouldn't that mean all humans are descendants of Noah. How do you explain black, Chinese, native American people having totally different features?"
Yes, it does mean that all humans today decended from the 4 couples on the Ark (Noah and wife plus 3 sons and their wives). That would ensure sufficient genetic diversity to account for all current races and ethnic groups.
However, I doubt that answer will satisfy you. So, let me make it even harder. Noah wasn't that far removed from Adam and Eve. So, those two had to contain the full genome (except for aberations) as it exists today. That really has to be hard for you to accept.
That's fantasy. Not to mention there's only one Y chromosome in the Noah family. We can trace the lineage of Y chromosomes, and it doesn't point to a recent common ancestor.
ROFL!!!! No, sorry, this is complete horse manure. You have absolutely no clue about the enormous amount of genetic diversity in the human population:
The patterns of natural variation in human genesThere is absolutely no freaking way that five people (Noah's sons don't count, they wouldn't have had any alleles that Noah and his wife didn't already have) could carry "sufficient genetic diversity" to account for modern humanity, period. Any population bottleneck that tiny would have had *very* obvious effects on human genetics for millions of years thereafter (if humanity had survived at all -- such bottlenecks can cause extinction due to severe inbreeding), which quite simply are not what we find when we look at the human genome.The abstract begins: "Currently, more than 10 million DNA sequence variations have been uncovered in the human genome. "
However, I doubt that answer will satisfy you.
Well, yeah, because we're not in the habit of being satisified by utter bull***t.
