As usual, I find your postings informative and interesting. Thanks.
However, I don't see why the existence of a fish species which has most of
its junk DNA removed justifies your conclusion. You write:
>> Obviously if one complex organism doesn't need the stuff, then it can't
have a very important function. <<
If we were to apply this reasoning to cheetahs we could conclude that
allele heterogeneity "can't have a very important function." But we know
better.
