Parsimonious explanations for punctuated patterns
Grade Level(s):
- 9-12
- 13-16
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.

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

Gene switches
Grade Level(s):
- 13-16
Source:
- Howard Hughes Medical Institute
Resource type:
- Classroom activity
Time: Two 45-minute blocks
Overview
This lesson explains how genetic switches function and their role in the process of evolution through the use of clips from the HHMI DVD, Evolution: Constant Change and Common Threads, and the construction of a model. This activity can be done as a demonstration, a student inquiry activity, or a combination of the two.
Evo in the News: What comes after mass extinctions?
Grade Level(s):

Source:
- UC Museum of Paleontology
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.

Especiación en tiempo real
Grade Level(s):
- 9-12
- 13-16
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.
