Belated Happy 271st Birthday, Jean Baptiste Pierre Antoine de Monet!
Who? The Chevalier de Lamarck, that’s who. Born 1 August 1744, he was the first evolutionary biologist who gave a mechanism that could, in principle, explain adaptation. Even though his mechanism was wrong, he was a true pioneer and a great biologist. (I’ll leave this post short, so as not to push Matt’s photo contest off the page).
