Honors and AP Biology Homework Chapter 14: Speciation

Homework

Reading Preparation

Textbook assignment: Chapter 14: The Origin of Species, sections 1-13 (all).

Study Notes

Keep in mind that "species" here is a group of organisms that interbreeds in the wild. This allows biologists to track individuals who are members of a group where genetic exchange occurs (speciation being the development of a distinct species), and isolate individuals who are not members of the group from consideration when trying to track evolutionary change. Members of different species (so defined) may actually be able to interbreed under laboratory conditions. Changes which lead to isolation of individual populations so that they no longer interbreed in the wilde — even when they are capable of doing so — are examples of macroevolution. If you read "species" in a narrow sense to mean groups of individuals that have radically different traits (like birds and fish), the chapter won't make sense.

Web Lecture

Read the following weblecture before chat: The Origin of Species<

Take notes on any questions you have, and be prepared to discuss the lecture in chat.

Perform the study activity below:

Use the Lizard Evoluion Virtual Lab to explore applications of the theory of eovlution to the anole lizard species of the Caribbean. Focus on Module 4. How does behavioral isolation work to create a separate species of lizard?
