The Hits Just Keep on Comingalready known to be true in animals; namely, that not only does the food that you eat carry with it instructions for your body, and not only does the food that your mother eats while pregnant with you also influence your body, but the feed that she eats before conception also influences your body.
Rural diet in The Gambia is predictable across the seasons, as the rainy and dry seasons come and go. So people born in The Gambia are walking biology experiments in that their birth date is a reliable predictor of their mother’s diet before and after conception.
And sure enough a new study reveals that small molecular markers, such as the methyl group, which are attached to our DNA and influence which genes are expressed, vary depending on when they were born. The differences are statistically significant and are consistent with what has already been found from various studies, preconception diet alters the epigenetic control of the genome.
With evolution we would have to believe that random mutations somehow created an astonishingly complex adaptation machine for no reason, and it just happened to persist in the population, and just happened to come in handy eons later, and so be preserved by that all-powerful creator known as natural selection. The sheer intricacies and interdependencies of epigenetics, and the lack of an evolutionary fitness pathway, are inconsistent with an evolutionary origin.
Nothing in biology makes any sense in the light of evolution.
