Lecture 8- Natural Selection Natural Selection What is Neo-Darwinism? Neo-darwinism is the unification of Mendelism with natural selection. Understanding neo-darwinism: 1. Mutation creates new genetic variants (all...

Lecture 7- Direct Observations of Change Cladogenesis Examples: 1. Freshwater fish are interesting models for rapid evolution. They are so closely tied to their water habitat that any time we have geological e...

Lecture 6- Biogeography Biogeography This is the study of the spatial locations of species. One key to finding species is the ecological niche that they can occupy. Ecological Niche: the set of conditions in which a s...

Evolution Exam 1 Lecture 1 – Why? Ultimate Causation: questions that examine why things exist. These questions poke at the ultimate scientific explanation for things. Proximal and Ul...

Lab safety is the cornerstone principle in this compelling Guide. All international safety symbols are clearly defined, with all basic lab glassware and equipment depicted by text description and diagrams. The Guide also p...
