Especiación en tiempo real

Grade Level(s):

  • 9-12
  • 13-16
  • General

Source:

  • UC Museum of Paleontology

Resource type:

  • Evo in the News article

Time: 30 minutes

Overview

Generalmente, pensamos en la especiación como un proceso lento. Toda la evidencia disponible sostiene la idea de que diferentes especies evolucionaron desde ancestros comunes, y sin embargo, nuevas especies no aparecen a nuestro alrededor diariamente. Para muchos biólogos, esto implica que la especiación ocurre tan lentamente que es difícil observarla en escalas de tiempo humanas. Sin embargo, nuevas investigaciones sugieren que la especiación podria ser más fácil de observar de lo que pensamos.

Resource type:

  • Evo in the News article

Time: 30 minutes

Overview

We often think of speciation as a slow process, so slow that we can't really observe it going on around us. This news brief from Febrary 2010 describes two examples which demonstrate that, at least occasionally, important steps toward speciation can be observed in less than 50 years.
