Résumé

LETTER 378. J.D. HOOKER TO CHARLES DARWIN. Kew, January 20th, 1867. Prof. Miquel, of Utrecht, begs me to ask you for your carte, and offers his in return. I grieve to bother you on such a subject. I am sick and tired of this carte correspondence. I cannot conceive what Humboldt's Pyrenean violet is: no such is mentioned in Webb, and no alpine one at all. I am sorry I forgot to mention the stronger African affinity of the eastern Canary Islands. Thank you for mentioning it. I cannot admit, without further analysis, that most of the peculiar Atlantic Islands genera were derived from Europe, and have since become extinct there. I have rather thought that many are only altered forms of existing European genera; but this is a very difficult point, and would require a careful study of such genera and allies with this object in view. The subject has often presented itself to me as a grand one for analytic botany. No doubt its establishment would account for the community of the peculiar genera on the several groups and islets, but whilst so many species are common we must allow for a good deal of migration of peculiar genera too.

L'auteur - Charles Darwin

Charles Darwin (12 février 1809 - 19 avril 1882) est un naturaliste anglais dont les travaux et les théories sur l'évolution des espèces vivantes ont profondément révolutionné la biologie. Il a développé l'hypothèse, appelée depuis "darwinisme", selon laquelle toutes les espèces vivantes ont évolué au cours du temps à partir d'un ancêtre commun - ou d'un petit nombre d'ancêtres communs - grâce au processus de sélection naturelle.
