The diversity of species

Authors: Bright, Michael;

The diversity of species

Abstract

Se estudian las diferencias físicas y genéticas que afectan a las distintas formas de vida que existen sobre la Tierra, cuya diversidad se calcula en catorce millones de especies de plantas, animales, algas, hongos y bacterias. Debido a esta gran diversidad de especies, ha sido necesario crear una clasificación, desde los más simples organismos, en la parte inferior hasta los más sofisticados en la superior. La evolución de las especies se realiza por el mecanismo de la selección natural estudiada por Darwin, que proporciona con el paso del tiempo adaptaciones o ajustes que preparan a un organismo para vivir en un lugar particular. Al final de cada tema aparece la reseña de científicos que han descrito y estudiado esta diversidad, y al final del libro hay una pequeña bibliografía y direcciones de páginas web.
