Long before having arrived at this part of my work, a crowd of difficulties will have occurred to the reader.<\/p>\n

Mucho antes de haber llegado a esta parte de mi trabajo, una multitud de dificultades se le habr\u00e1n ocurrido al lector.<\/p>\n

 <\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

Some of them are so grave that to this day I can never reflect on them without being staggered; but, to the best of my judgment, the greater number are only apparent, and those that are real are not, I think, fatal to my theory.<\/p>\n

 <\/p>\n

Algunas de ellas son tan graves que, hasta hoy, no puedo reflexionar sobre ellas sin titubeo, pero, a lo mejor de mi juicio, el mayor n\u00famero de ellas son s\u00f3lo aparentes, y las que son reales no son, creo, fatales para mi teor\u00eda.<\/p>\n

 <\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

These difficulties and objections may be classed under the following heads:\u2014Firstly, why, if species have descended from other species by insensibly fine gradations, do we not everywhere see innumerable transitional forms? Why is not all nature in confusion instead of the species being, as we see them, well defined?<\/p>\n

 <\/p>\n

Estas dificultades y objeciones pueden clasificarse en los siguientes tipos:-En primer lugar, \u00bfpor qu\u00e9, si las especies han descendido de otras especies por gradaciones insensiblemente finas, no se ven por todas partes innumerables formas de transici\u00f3n? \u00bfPor qu\u00e9 no est\u00e1 toda la naturaleza confusa, en lugar de las especies, como las vemos, bien definidas?<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

Secondly, is it possible that an animal having, for instance, the structure and habits of a bat, could have been formed by the modification of some animal with wholly different habits? Can we believe that natural selection could produce, on the one hand, organs of trifling importance, such as the tail of a giraffe, which serves as a fly-flapper, and, on the other hand, organs of [172]such wonderful structure, as the eye, of which we hardly as yet fully understand the inimitable perfection?<\/p>\n

 <\/p>\n

En segundo lugar, es posible que un animal que tiene, por ejemplo, la estructura y las costumbres de un murci\u00e9lago, pudiera haberse formado por la modificaci\u00f3n de un animal con h\u00e1bitos totalmente diferentes? \u00bfPodemos creer que la selecci\u00f3n natural podr\u00eda producir, por una parte, \u00f3rganos de escasa importancia,
\ntales como la cola de una jirafa, que sirve como espanta-moscas, y, por por otra parte, \u00f3rganos de [172] tan maravillosa estructura, tales como el ojo, de los cuales apenas entendemos plenamente la perfecci\u00f3n inimitable?<\/p>\n

 <\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

Thirdly, can instincts be acquired and modified through natural selection? What shall we say to so marvellous an instinct as that which leads the bee to make cells, which has practically anticipated the discoveries of profound mathematicians?<\/p>\n

 <\/p>\n

En tercer lugar, pueden los \u00a0instintos adquirirse y modificarse por selecci\u00f3n natural? \u00bfQu\u00e9 vamos a decir de un instinto tan maravilloso como el que lleva la abeja para hacer las celdas, que pr\u00e1cticamente se ha anticipado a los descubrimientos de matem\u00e1ticos profundos?<\/p>\n

\"\"<\/p>\n

 <\/p>\n

Fourthly, how can we account for species, when crossed, being sterile and producing sterile offspring, whereas, when varieties are crossed, their fertility is unimpaired?<\/p>\n

En cuarto lugar, \u00bfc\u00f3mo podemos explicar que cuando se cruzan las especies son est\u00e9riles y producen descendencia est\u00e9ril, mientras que, cuando se cruzan las variedades, la fertilidad no se ve afectada?<\/p>\n
