PRONTO SEREMOS TODOS MESTIZOS

PRONTO SEREMOS TODOS MESTIZOS

Por Marcelino Ortiz (Colaborador de la AIN)

Pronto seremos todos mestizos.
Así los afirma el sabio  André Langaney, genetista, profesor del Museo Nacional de Historia Natural y de laUniversidad de Ginebra, en un artículo publicado en la revista científica Science et Avenir.

Langaney explica que esto no es nada nuevo,  porque nuestros mestizajes provienen o se desarrollaron, desde hace uno miles de siglos por lo menos, pues todos los humanos actuales descienden de una sola población pequeña de menos de 100 000 cazadores recolectores.
 

Venidos de África o del Cercano Oriente, estos antepasados conquistaron al Antiguo mundo y luego el Nuevo.  No muy numerosos, sus descendientes se adaptaron, volviéndose más oscuros bajo los trópicos, y más claros en el norte y en el sur; más altos en las zonas templadas y en el desierto caliente y más pequeños en los bosques ecuatoriales o las zonas polares.

Después de domesticar las plantas y los animales hace una decena de millones de años, su población creció por millares guardando sus rasgos físicos, formando así las "razas" reconocibles por sus características faciales y culturales.

Después, las grandes ciudades se convirtieron en crisoles donde los hombres se mezclaron por sentimientos afines, dando como resultado a humanos de origen confuso.

Pero atención: no hay que equivocarse con el efecto de este mestizaje, pues no se produce una uniformización de las poblaciones o de los colores de piel.
Al contrario, favorece la aparición de combinaciones nuevas: cabellos crespos y rubios, ojos azules y rasgados.   

En Latinoamérica, Brasil, en las Seychelles o en otro lugar del mundo, el mestizaje se multiplica y por ello, mientras más pase el tiempo, más mestizos seremos.
