In the Azores, from the large number of plants common to Europe, in comparison with the species on the other islands of the Atlantic, which stand nearer to the mainland, and (as remarked by Mr. H.C. Watson) from their somewhat northern character, in comparison with the latitude, I suspected that these islands had been partly stocked by ice-borne seeds during the Glacial epoch. At my request Sir C. Lyell wrote to M. Hartung to inquire whether he had observed erratic boulders on these islands, and he answered that he had found large fragments of granite and other rocks, which do not occur in the archipelago. Hence we may safely infer that icebergs formerly landed their rocky burdens on the shores of these mid-ocean islands, and it is at least possible that they may have brought thither the seeds of northern plants.<\/em><\/p>\n<p style=\"text-align: justify;\"><em>\u00a0<\/em><\/p>\n<p style=\"text-align: justify;\"><em>Como es sabido que los icebergs est\u00e1n a veces cargados de tierra y piedras, y que hasta han transportado matorrales, huesos y el nido de un p\u00e1jaro terrestre, apenas puede dudarse que ocasionalmente pudieron haber transportado, como ha sido sugerido por Lyell, semillas de una parte a otra de las regiones \u00e1rticas y ant\u00e1rticas y, durante el per\u00edodo glaciar, de una parte a otra de las regiones que hoy son templadas. En las Azores -por el gran n\u00famero de plantas comunes a Europa, en comparaci\u00f3n con las especies de otras islas del Atl\u00e1ntico que est\u00e1n situadas m\u00e1s cerca de tierra firme y, como ha sido observado por m\u00edster H. C. Watson, por su car\u00e1cter algo septentrional en comparaci\u00f3n con la latitud- sospech\u00e9 que estas islas han sido en parte pobladas por semillas tra\u00eddas por los hielos durante la \u00e9poca glaciar. A ruego m\u00edo, sir C. Lyell escribi\u00f3 a m\u00edster Hartung pregunt\u00e1ndole si habla observado cantos err\u00e1ticos en estas islas, y contest\u00f3 que hab\u00edan hallado grandes pedazos de granito y de otras rocas que no se encuentran en el archipi\u00e9lago. Por consiguiente, podemos deducir con seguridad que los icebergs en otro tiempo depositaron su carga de piedras en las playas de estas islas oce\u00e1nicas, y es, por lo menos, posible que puedan haber llevado a ellas algunas semillas de plantas del Norte.<\/em><\/p>\n<p>Lectura aconsejada:<\/p>\n<ul>\n<li><a href=\"https:\/\/digital.csic.es\/handle\/10261\/76630\"> Manual para detectar la impostura cient\u00edfica: Examen del libro de Darwin por Flourens.<\/a> Digital CSIC, 2013. 225 p\u00e1ginas.<\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><br clear=\"all\" \/> <strong><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Entre los medios de transporte se encuentran tambi\u00e9n los iceberg.\u00a0 No en vano sir C.
