With respect to the assumed inutility of various parts and organs, it is hardly necessary to observe that even in the higher and best-known animals many structures exist, which are so highly developed that no one doubts that they are of importance, yet their use has not been, or has only recently been, ascertained. As Bronn gives the length of the ears and tail in the several species of mice as instances, though trifling ones, of differences in structure which can be of no special use, I may mention that, according to Dr. Schobl, the external ears of the common mouse are supplied in an extraordinary manner with nerves, so that they no doubt serve as tactile organs; hence the length of the ears can hardly be quite unimportant. We shall, also, presently see that the tail is a highly useful prehensile organ to some of the species; and its use would be much influence by its length.<\/em><\/p>\n<p style=\"text-align: justify;\"><em>\u00a0<\/em><\/p>\n<p style=\"text-align: justify;\"><em>Merecer\u00e1 la pena aclarar con ejemplos algunas de las observaciones anteriores. Por lo que se refiere a la pretendida inutilidad de varias partes y \u00f3rganos, casi no es necesario hacer observar que, aun en los animales superiores y mejor conocidos, existen muchas estructuras que est\u00e1n tan desarrolladas que nadie duda que son de importancia, cuyo uso no ha sido averiguado o lo ha sido recientemente. Como Bronn cita la longitud de las orejas y de la cola en las diferentes especies de ratones como ejemplos, aunque insignificantes, de diferencias de conformaci\u00f3n que no pueden ser de utilidad especial alguna, debo recordar que, seg\u00fan el doctor Sch\u00f6bl, las orejas del rat\u00f3n com\u00fan est\u00e1n extraordinariamente provistas de nervios, de manera que indudablemente sirven como \u00f3rganos t\u00e1ctiles, y, por consiguiente, la longitud de las orejas es dif\u00edcil que pueda carecer por completo de importancia. Veremos luego, adem\u00e1s, que la cola es un \u00f3rgano prensil util\u00edsimo a algunas especies, y su longitud tiene que influir mucho en su utilidad.<\/em><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>Lectura aconsejada:<\/p>\n<p><a href=\"https:\/\/digital.csic.es\/handle\/10261\/76630\">\u00a0Manual para detectar la impostura cient\u00edfica: Examen del libro de Darwin por Flourens.<\/a> Digital CSIC, 2013. 225 p\u00e1ginas.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>El autor habla de utilidad o de inutilidad seg\u00fan le viene y le parece a \u00e9l.\u00a0 As\u00ed lo que se encuentra muy desarrollado ha de ser \u00fatil: With respect to the assumed inutility of various parts and organs, it is hardly necessary to observe that even in the higher and best-known animals many structures exist, which are so highly developed that no one doubts that they are of importance, yet their use has not been, or has only recently been, ascertained.
