 * Evolution Unit:**
 * 1. Genetic Variation Group:**
 * **View [|The Red Queen]**
 * **View [|A Mutation Story]**
 * **Visit the [|Microbe Clock]**
 * Finally...__Take notes__ as you view the segments. Write short summaries and prepare a short presentation for the class about the factors that provide genetic variation (sexual reproduction, mutation), why genetic variation is important for the survival of a species, and how variation makes natural selection possible. Cite specific examples from the sources they viewed.


 * 2. Adaptation Group:**
 * View the [|Evolution of Camouflage] video
 * View the [|Shape of Trees: The Frustration Principle] image
 * View [|Mimicry: The Orchid and the Bee] and read the corresponding backgrounders.
 * Take notes on the segments and readings, then write paragraph summaries and prepare a short presentation for the class about the role adaptation plays in the process of natural selection. Consider external influences such as predators, competitors for food, and access to mates (or, in the orchid's case, pollinators.


 * 3. Sexual Selection Group:**
 * View the [|Tale of the Peacock] video
 * View the [|The Mating Game] Web feature
 * View [|Sweaty T-shirts and Human Mate Choice] video.
 * Take notes and try out the Web feature. Take notes on the segments and readings, then write paragraph summaries and prepare a short presentation for the class about the role sexual selection plays in the process of natural selection. Consider why male competition and female choice have evolved as a selection means in many species and the importance partner selection plays in genetic diversity.

1. [|Classification] - Introduction to Classification of Life 2. [|Dichotomous Keys-]Instructions: In completion of this unit you will be asked to create a dichotomous key, go here to learn what they are, how to make one and how to use them! Once on the page __**First,**__ go to the link __"What is a key__", read through that page and **then** follow the link **__"How to make a key__**". Attempt **to identify** the sample organisms on the page in the interactive key at the bottom (This is an extremely watered down interactive but it gets the point across). **Follow t**he link at the top of the page to __**"What are these things?"**__ and __**use the interactive ke**__y to identify organisms( this is a bit more challenging). We will continue with Dichotomous keys next class.
