The sudden manner in which several groups of species first appear in our European formations, the almost entire absence, as at present known, of formations rich in fossils beneath the Cambrian strata, are all undoubtedly of the most serious nature. We see this in the fact that the most eminent palaeontologists, namely, Cuvier, Agassiz, Barrande, Pictet, Falconer, E. Forbes, etc., and all our greatest geologists, as Lyell, Murchison, Sedgwick, etc., have unanimously, often vehemently, maintained the immutability of species. But Sir Charles Lyell now gives the support of his high authority to the opposite side, and most geologists and palaeontologists are much shaken in their former belief. Those who believe that the geological record is in any degree perfect, will undoubtedly at once reject my theory. For my part, following out Lyell&#8217;s metaphor, I look at the geological record as a history of the world imperfectly kept and written in a changing dialect. Of this history we possess the last volume alone, relating only to two or three countries. Of this volume, only here and there a short chapter has been preserved, and of each page, only here and there a few lines. Each word of the slowly-changing language, more or less different in the successive chapters, may represent the forms of life, which are entombed in our consecutive formations, and which falsely appear to have been abruptly introduced. On this view the difficulties above discussed are greatly diminished or even disappear.<\/em><\/p>\n<p style=\"text-align: justify;\"><em>\u00a0<\/em><\/p>\n<p style=\"text-align: justify;\"><em>\u00a0<\/em><\/p>\n<p style=\"text-align: justify;\"><em>Las varias dificultades que aqu\u00ed se discuten (a saber: que aun cuando encontramos en las formaciones geol\u00f3gicas muchas formas de uni\u00f3n entre las especies que ahora existen y las que existieron anteriormente, no encontramos un n\u00famero infinito de delicadas formas de transici\u00f3n que unan estrechamente a todas ellas; la manera s\u00fabita como aparecen por vez primera en las formaciones europeas varios grupos de especies; la ausencia casi completa -en lo que hasta ahora se conoce- de formaciones ricas en f\u00f3siles por debajo de los estratos c\u00e1mbricos) son todas indudablemente dificultades de car\u00e1cter grav\u00edsimo. Vemos esto en el hecho de que los m\u00e1s eminentes paleont\u00f3logos, como Cuvier, Agassiz, Barrande, Pictet, Falconer, E. Forbes, etc., y todos nuestros mayores ge\u00f3logos, como Lyell, Murchison, Sedgwick, etc., un\u00e1nimemente -y muchas veces vehementemente- han sostenido la inmutabilidad de las especies. Pero sir Charles Lyell ahora presta el apoyo de su alta autoridad al lado opuesto, y la mayor parte de los ge\u00f3logos y paleont\u00f3logos vacilan en sus convicciones anteriores. Los que crean que los registros geol\u00f3gicos son en alg\u00fan modo perfectos rechazar\u00e1n desde luego indudablemente mi teor\u00eda. Por mi parte, siguiendo la met\u00e1fora de Lyell, considero los registros geol\u00f3gicos como una historia del mundo imperfectamente conservada y escrita en un dialecto que cambia, y de esta historia poseemos s\u00f3lo el \u00faltimo volumen, referente nada m\u00e1s que a dos o tres siglos. De este volumen s\u00f3lo se ha conservado aqu\u00ed y all\u00e1 un breve cap\u00edtulo, y de cada p\u00e1gina, s\u00f3lo unas pocas l\u00edneas saltadas. Cada palabra de este lenguaje, que lentamente var\u00eda, es m\u00e1s o menos diferente en los cap\u00edtulos sucesivos y puede representar las formas org\u00e1nicas que est\u00e1n sepultadas en las formaciones consecutivas y que err\u00f3neamente parece que han sido introducidas de repente. Seg\u00fan esta opini\u00f3n, las dificultades antes discutidas disminuyen notablemente y hasta desaparecen.<\/em><\/p>\n<p>&nbsp;<\/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>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dice el autor: &nbsp; Los que crean que los registros geol\u00f3gicos son en alg\u00fan modo perfectos rechazar\u00e1n desde luego indudablemente mi teor\u00eda. &nbsp; Y se equivoca.
