En teor\u00eda, debido a \u00e9ste y otros costes a\u00f1adidos de la reproducci\u00f3n sexual, la selecci\u00f3n natural deber\u00eda apostar por la alternativa asexual, m\u00e1s rentable a corto plazo. Sin embargo, en el mundo vivo encontramos sexo por doquier: es la modalidad reproductiva mayoritaria en animales, plantas, hongos y muchas otras formas de vida, por lo que cabe preguntarse cu\u00e1l es la ventaja del sexo sobre la clonaci\u00f3n asexual. No es extra\u00f1o que, para los bi\u00f3logos, el sexo sea el \u00abproblema de los problemas\u00bb evolutivos.Garc\u00eda Leal, despu\u00e9s de examinar todas las propuestas de soluci\u00f3n del problema, expone la suya propia, basada en el principio de independencia de la incertidumbre del entorno, es decir, en la necesidad de adaptarse a un entorno impredecible. Adem\u00e1s plantea otro problema evolutivo: la existencia de sexos diferenciados. En principio, nada impide que las especies sexuales est\u00e9n constituidas por hermafroditas, pero en el mundo vivo el hermafroditismo es la excepci\u00f3n. La existencia de sexos, y en particular de dos sexos, es tan enigm\u00e1tica como el sexo mismo. \u00bfPor qu\u00e9 hay machos y hembras? Sobre esta y otras muchas cuestiones arroja luz El sexo de las lagartijas.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ambrosio Garc\u00eda Leal<\/p>\n","protected":false},"featured_media":64089,"comment_status":"open","ping_status":"closed","template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[23],"product_cat":[10105,5808,5807,5806],"product_tag":[5925],"class_list":["post-16202","product","type-product","status-publish","has-post-thumbnail","product_brand-epub-paradise","product_cat-ambrosio-garcia-leal","product_cat-ebooks","product_cat-epub","product_cat-espanol","product_tag-ciencias-naturales","desktop-align-center","tablet-align-left","mobile-align-center","first","instock","taxable","shipping-taxable","purchasable","product-type-variable"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.7 -
