En biolog\u00eda no hay una definici\u00f3n precisa para raza, particularmente trat\u00e1ndose de seres humanos. El concepto de raza est\u00e1 siendo debatido desde que lo estableci\u00f3 el m\u00e9dico y naturalista alem\u00e1n Johann Friedrich Blumenbach (1753-1840), lo que se debe no propiamente a problemas cient\u00edficos sino a su aplicaci\u00f3n a teor\u00edas odiosas de discriminaci\u00f3n y persecuci\u00f3n, englobadas bajo el t\u00e9rmino racismo Desde el punto de vista formal, una raza podr\u00eda ser considerada como una sub especie, lo que podr\u00eda ser explicado como un grupo de individuos de la misma especie que presentan caracter\u00edsticas semejantes. Eso puede incluir color de piel, grupos sangu\u00edneos, estatura, etc. En los animales dom\u00e9sticos, la distinci\u00f3n de raza es m\u00e1s obvia porque all\u00ed existe la selecci\u00f3n natural. Los criadores a\u00edslan gatos, perros, caballos y aves y dirigen sus intereses -luego de algunas generaciones- a la aparici\u00f3n de nuevos grupos o razas que van a presentar una identidad gen\u00e9tica mucho m\u00e1s grande, tanto que no existir\u00e1 barrera reproductiva entre ellas. En los seres humanos, no sujetos a selecci\u00f3n artificial, las diferencias gen\u00e9ticas son entonces m\u00e1s discretas. El estudio de diferentes marcadores gen\u00e9ticos, ya dej\u00f3 en claro que existen pocas diferencias entre los individuos oriundos de etnias bastante distintas, como, por ejemplo, entre pobladores estables separados por continentes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Fuente: Diccionario Cient\u00edfico \u2013 Sergio Prenafeta J.\u00a0<\/p>\n\n\n\n<div style=\"height:25px\"
