You know, these Nibbles (the short, soundbite-type things which appear at the top of the right sidebar of this page) are fun to do, but sometimes you end up downplaying, or over-simplifying, an important, interesting — and interestingly complex — story. Take what I said about the American chestnut a few days ago. The recent history of Castanea dentata is proud and tragic ((Looking further back, it also played an important role in native America agroforestry.)), and efforts to bring it back from the brink of annihilation well-nigh heroic. To imply, as I did, that these efforts were confined to hybridizing the American with the Chinese chestnut was justified only by the necessity for extreme brevity. In fact, of course, it is not just hybridization but repeated back-crossing. And not just interspecific crossing but also painstaking crossing among the few remaining pure American chestnuts, as reported in the article that prompted me to revisit the original story and hopefully make amends for my earlier flippancy.
