Please don’t hold back, tell me how you really feel! :o)
From my quoted source “unequivocally positive mutations are unknown to genetics, since they have never been observed...”
Lactose intolerance is that all you got? I regret to say I read your entire post... err ranting... and came away with very little connstructive information from you.
Your pomposity did shine through once again though. :’)
Evos are nothing if not arrogant.
unequivocally positive mutations are unknown to genetics, since they have never been observed
...is a well-couched false statement. "Beneficial" is a couched phrase, "unequivocally" is a couched phrase.....and "unknown to genetics, since they have never been observed" is a lie liek saying "there have been no mutations that ensure a life span of 400 years.
Lactose intolerance is that all you got?
To prove a lie that they don't exist.....that's all that's needed. Need more? Lipoprotein lipase mutations (3 known)? Coagulation factor VII mutations. The CCR5 delta 32 mutation.
I wouldn't expect for you to get anything from me, you've done "research" on "YEC sites"...where dinosaurs live in the time of Man.
Beneficial is as beneficial does, Forrest.
Yes, a mutation causing adult lactase production is a beneficial trait, increasing genetic fitness by increasing nutrition, decreasing malnutrition throughout breeding ages.
Yes, it will also have the negative cause of a higher fat diet, higher body fat, and more heart attacks......LONG AFTER REPRODUCTION AGE. As in, they have limited negative affects on genetic fitness that are overshadowed by the increase in genetic fitness.......which is why the prevalence of the known mutations is increasing in the population. Breast cancer genes persist because they don't kill the individual until after they have kids. They REALLY persist in place liek Iceland because of the island effect....little genetic variability.
