Description
Los embriones pueden parecernos seres indefensos, pero pocas personas saben que son unos inconformistas natos: cualquier modificación genética que afecte su desarrollo se traducirá en cambios anatómicos o funcionales en los adultos que, por leves que parezcan, son la piedra angular de la evolución y de la selección natural. Cambiar para sobrevivir, sobrevivir para cambiar. Si los embriones no estuvieran abocados al cambio, la evolución de los metazoos, es decir, de todos los animales, no habría sido posible. La evolución y el desarrollo embrionario forman una aleación biológica resistente y flexible. Este es el campo de estudio de la evo-devo, una nueva disciplina científica que investiga cómo los mecanismos evolutivos hacen posible que organismos que comparten un antepasado, como los gusanos, los insectos y los vertebrados, sean tan diferentes. Pero solo son diferentes en apariencia, porque uno de los principales hallazgos de la evo-devo es que genéticamente tienen mucho en común. Con un lenguaje asequible, ejemplos sorprendentes y experimentos fascinantes, el lector descubrirá en este libro cómo y por qué el desarrollo embrionario condiciona la evolución, incluida la de los humanos.
