Epigenetic inheritance, as in histone modifications, methylated fragments of DNA and so
on, are TEMPORARY factors that may transcend a generation or two, but lack
permanence to make "evolutionary" change
Also, biologists have shown that "epigenetic change", like methylation of
DNA, is actually coded for in the DNA, so what one has is nothing but a
normal alteration of the phenotype (the DNA) by normal boring nucleotide
mutations in the DNA.
Which is it? Temporary methylation or lasting changes to the DNA? You seem to be rejecting and supporting it at the same time.
By the way, there are is variety of ways to inherit traits beyond DNA as outlined in: Eva, Jablonska, and Lamb, Marion. "Evolution in Four Dimensions." (2005).
