As\u00ed, un ciudadano de la Antigua Grecia que viajara en el tiempo hasta hoy ser\u00eda mucho m\u00e1s inteligente: tendr\u00eda m\u00e1s imaginaci\u00f3n y mejor memoria.<\/p>\n<p>Seg\u00fan el bi\u00f3logo, la inteligencia humana depende de entre 2 mil y 5 mil genes. Diversas investigaciones muestran que este patrimonio gen\u00e9tico es especialmente susceptible de sufrir mutaciones. Y Crabtee cree que en las \u00faltimas 120 generaciones (unos 3 mil a\u00f1os), la humanidad ha ido perdiendo inteligencia poco a poco.<\/p>\n<p>Su tesis es la siguiente: como el hombre primitivo no utilizaba el cerebro, no pod\u00eda alimentarse ni protegerse de animales salvajes, por lo que s\u00f3lo los m\u00e1s inteligentes sobreviv\u00edan. Esta presi\u00f3n selectiva hizo, seg\u00fan Crabtee, que la inteligencia humana aumentara de forma constante.<\/p>\n<p>Sin embargo, desde la implantaci\u00f3n de la agricultura, los hombres vivieron en grupos m\u00e1s grandes que proteg\u00edan a los m\u00e1s d\u00e9biles.<\/p>\n<p>Entonces, protegerse de las enfermedades que surgen de las aglomeraciones era m\u00e1s importante que la inteligencia.<\/p>\n<p>El experto contradice as\u00ed otros estudios que afirman que el coeficiente intelectual medio aumenta de generaci\u00f3n en generaci\u00f3n desde comienzos del siglo XX. Es el llamado \u00abefecto Flynn\u00bb, que lleva el nombre del investigador James Robert Flynn.<\/p>\n<p><strong>Humans Are Getting Dumber And Dumber, Says Stanford Researcher<\/strong><br \/>\nHave you ever felt like your fellow humans are just getting stupider and more emotional? You&#8217;re not mistaken.<\/p>\n<p>A Stanford University researcher (aptly named Gerald Crabtree) has furthered a similar theory &#8212; that we are now way less smart or \u00abemotionally stable\u00bb than our cave-dwelling forebearers.<br \/>\n\u00abI would be willing to wager that if an average citizen of Athens of 1,000 BC were to appear suddenly among us, he or she would be among the brightest and most intellectually alive of our colleagues and companions,\u00bb Crabtree wrote in a study that appeared in Trends in Genetics. \u00abI would also guess that he or she would be among the most emotionally stable of our friends and colleagues.\u00bb<\/p>\n<p>How come? Crabtree speculates that in our comfortable world, evolutionary pressures are far less intense, leading to a higher preponderance of dumber people. Even worse, Crabtree hypothesizes that in 3,000 years, humans will endure two or more harmful mutations to our DNA due to all this easy living.<\/p>\n<p>A February New York Times opinion article posited \u00abthe average person today would be 30 points above his or her grandparents\u00bb on an IQ test, but the author stopped short or saying we are smarter than our ancestors. Instead, he said that we are \u00abmore modern\u00bb in our thinking.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>El coeficiente intelectual de la humanidad disminuye paulatinamente, o al menos as\u00ed lo afirma un estudio realizado por el bi\u00f3logo Gerald Crabtree, de la Universidad de Stanford, en California.
