 <\/p>\n

Since natural selection maximizes the number of surviving offspring, it seems at first sight that selection should favour the largest possible seed output. However, if large seeds (and thus largers sedlings) are better able to overcome some environmental hazards, then the greater probability of survival of larger seedlings might overweigh their smaller numbers.<\/em><\/p>\n

Que traduzco:<\/p>\n

Como la selecci\u00f3n natural maximiza el n\u00famero de cr\u00edas supervivientes, a primera vista parece que la selecci\u00f3n debe favorecer la mayor producci\u00f3n de semillas posible. Sin embargo, si las semillas de gran tama\u00f1o (y por lo tanto pl\u00e1ntulas grandes) est\u00e1n en mejores condiciones para superar algunos de los riesgos ambientales, la mayor probabilidad de supervivencia de las pl\u00e1ntulas de mayor tama\u00f1o podr\u00eda contra-restar sus n\u00fameros m\u00e1s peque\u00f1os.<\/em><\/p>\n

 <\/p>\n

Afirmaciones de esta \u00edndole vienen a ser suficientes para algunos como explicaci\u00f3n de la formaci\u00f3n de especies.<\/p>\n
