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.

Sin embargo, nuevas investigaciones sugieren que la especiación podria ser más fácil de observar de lo que pensamos.
