It is this continual process of genetic drift gives rise to the seasonal epidemics of flu and norovirus.

During this process of transformation - or genetic drift - the virus alters its appearance and the immune memory cells struggle to recognise it.

Modern evolutionary biology as we understand it, which is to say variation via genetic drift, mutations, duplications combined with the pruning filter of natural selection, certainly explains a great deal.

The lawsuits, pain and suffering for all involved, the questions of hybridized genetic drift, far too massive, scientifically complex, and global in scope to even intimate in an opinionated response to a vested opinion.

What we learn from these areas is precisely how evolution has acted to sculpt bodies, but it still does so using randomly-generated genetic variation and good old natural selection (and yes, Larry Moran, genetic drift also plays a role).
