There is no exception to the rule that every organic being naturally increases at so high a rate, that, if not destroyed, the earth would soon be covered by the progeny of a single pair. Even slow-breeding man has doubled in twenty-five years, and at this rate, in less than a thousand years, there would literally not be standing room for his progeny. Linnaeus has calculated that if an annual plant produced only two seeds\u2014and there is no plant so unproductive as this\u2014and their seedlings next year produced two, and so on, then in twenty years there would be a million plants. The elephant is reckoned the slowest breeder of all known animals, and I have taken some pains to estimate its probable minimum rate of natural increase; it will be safest to assume that it begins breeding when thirty years old, and goes on breeding till ninety years old, bringing forth six young in the interval, and surviving till one hundred years old; if this be so, after a period of from 740 to 750 years there would be nearly nineteen million elephants alive descended from the first pair.<\/em><\/p>\n

No existe excepci\u00f3n de la regla de que todo ser org\u00e1nico aumenta naturalmente en progresi\u00f3n tan alta y r\u00e1pida, que, si no es destruido, estar\u00eda pronto cubierta la tierra por la descendencia de una sola pareja. Aun el hombre, que es lento en reproducirse, se ha duplicado en veinticinco a\u00f1os, y, seg\u00fan esta progresi\u00f3n, en menos de mil a\u00f1os, su descendencia no tendr\u00eda literalmente sitio para estar en pie. Linneo ha calculado que si una planta anual produce tan s\u00f3lo dos semillas -y no hay planta tan poco fecunda- y las plantitas salidas de ellas producen en el a\u00f1o siguiente dos, y as\u00ed sucesivamente, a los treinta a\u00f1os habr\u00eda un mill\u00f3n de plantas. El elefante es considerado como el animal que se reproduce m\u00e1s despacio de todos los conocidos, y me he tomado el trabajo de calcular la progresi\u00f3n m\u00ednima probable de su aumento natural; ser\u00e1 lo m\u00e1s seguro admitir que empieza a criar a los treinta a\u00f1os, y que contin\u00faa criando hasta los noventa, produciendo en este intervalo seis hijos, y que sobrevive hasta los cien a\u00f1os; y siendo as\u00ed, despu\u00e9s de un per\u00edodo de 740 a 750 a\u00f1os habr\u00eda aproximadamente diez y nueve millones de elefantes vivos descendientes de la primera pareja.<\/em><\/p>\n
