Especiación en tiempo real
Grade Level(s):

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: 20 minutes
Overview
More than 500 species of cichlid fish inhabit Africa's Lake Victoria. This news brief from March 2009 explains new research suggesting that the physics of light may have played an important role in cichlid diversification and in the recent drop in their diversity.

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.

Island biogeography and evolution: Solving a phylogenetic puzzle using molecular genetics
Grade Level(s):
- 9-12
- 13-16
Source:
- Filson, R.P.
Resource type:
- Lab activity
Time: Two full class periods
Overview
Students focus on the evolution of three species of lizards using real data sets — geographical and geological data, then morphology, and finally molecular data — to determine possible phylogenetic explanations.

Parsimonious explanations for punctuated patterns
Grade Level(s):

- 13-16
- General
Source:
- Evolution: Education and Outreach
Resource type:
- Article
Time: 40 minutes
Overview
Punctuated equilibrium is sometimes erroneously cited as evidence that evolutionary biology still hasn't figured out how evolution works. In fact nothing could be further from the truth. Punctuated equilibrium builds on (not tears down!) established evolutionary theory. Find out how the process works.

Resource type:
- Video Lecture
Time: 60 minutes
Overview
In lecture two of a four part series, evolutionary biologist David Kingsley discusses how just a few small genetic changes can have a big effect on morphology, using examples from maize, dog breeding, and stickleback fish.
This lecture is available from Howard Hughes' BioInteractive website.
