Evolution Heresy? Epigenetics Underlies Heritable Plant Traits

"For some evolutionary biologists, just hearing the term epigenetics raises hackles. They balk at suggestions that something other than changes in DNA sequences, such as the chemical addition of methyl groups to DNA or other so-called epigenetic modifications, has a role in evolution. Yet a provocative study presented at an evolutionary biology meeting last month found that heritable changes in plant flowering time and other traits were the result of epigenetics alone, unaided by any sequence changes."
