Metazoan Study guides, Class notes & Summaries

Pre-lab: Introduction to Lab 8 In this, the *nal lab of the quarter, you will be asked to solve a series of small puzzles in metazoan evolution. In BIS 2A you learned about mechanisms of genetic change, and in BIS 2B you learned how natural selection operates on individuals to produce genetic change in populations. You realize now that agents of natural selection can be biotic factors, such as interactions with predators and prey, as well as abiotic factors, such as temperature or moisture...
