1. Warm up Warm Up Work sheet is supplied
Key Idea from Activity 229: Evolution by natural selection describes how organisms that are better adapted to their environment survive to produce a greater number of offspring.
Key Idea from Activity 230: Adaptation is any heritable trait that suits an organisms to it’s natural functional role in the environment.
Key Idea A from Activity 231: Unrelated species often evolve similar adaptations to overcome the same environmental changes. COVERGENT EVOLUTION
Key Idea B from Activity 231: The effect of natural selection on a population can be verified by making quantitative measurements of phenotypic traits.
Key Idea from Activity 233 The need to blend into their surroundings is an important selective pressure on the coat color of rock pocket mice.
Key Idea from Activity 237: a species is a very specific unit of taxonomy given to a group of organisms with similar characteristics.
Key Idea from Activity 238: Gene Flow is reduced when populations are separated. Continual reduction in gene flow by isolating mechanisms may eventually lead to the formation of new species. GEOGRAPHIC and REPRODUCTIVE ISOLATION.
Key Idea from Activity 239: Populations moving into a new environment may diverge from their common ancestor and form new species. DIVERGENT EVOLUTION ,ADAPTIVE RADIATION, SEQUENTAL EVOLUTION, PHYLETIC GRADUALISM, PUNTUATED EQUILIBRIUM.
Key Idea from Activity 240: Mammal underwent an adaptive radiation around 65 million years ago, will be covered today
Acquired characteristics: A change of function or structure in an organism made in response to the environment; a non-inheritable trait that results from certain environmental influences.

2. natural selection: are better adapted to their environment
For dogs early in the domestication process, duplication of amylase genes happened as a one time, chance mutation event, Dogs that carried the duplicated the amylase gene reproduced at a slightly greater frequency than dogs without it. This duplicated amylase allele allowed for dogs to derive more nutrition from the food they were receiving from their new environment which is human supplied.
Using the key ideas below, Explain what will happen over time to the frequencies of the duplicating and non-duplicating amylase alleles. You can use bullet points if you want to.
natural selection: are better adapted to their environment
Adaptation : that suits an organisms to it’s natural functional role in the environment
population can be verified by making quantitative measurements of amylase gene

3. DUE TODAY: 1 page of notes (0-2 pts)
Rough draft Due December 4th
Honors paper and presentation due December11
Unit test December 4th
Finals Game Project Due December 8th; Rubric and instructions on my website; I have something to help you with the questions
6 Block Days left

4. My Thoughts on the Evolution Unit test: We could postpone the test till next Wednesday or have it on Monday: Advantage: more time to absorb the content. Disadvantage: less time to prepare for Final.
No Postponement:
Have to be effective and efficient in working as pairs:
Reading the content material in the activities individually and then sharing understanding as answering the posed questions.
A few will need to come in for tutoring help with understanding the content.

5. Microevolution: Change in Allele Frequency
Genetic Drift: small population, gene shuffling (recombination of genes)
Non-random Mating: sexual selection
Mutations
Gene Flow: Geographic and reproductive Isolation
Natural Selection

6. Key Idea from Activity 238: Gene Flow is reduced when populations are separated. Continual reduction in gene flow by isolating mechanisms may eventually lead to the formation of new species. GEOGRAPHIC and REPRODUCTIVE ISOLATION.

7. Key Idea from Activity 239: Populations moving into a new environment may diverge from their common ancestor and form new species. DIVERGENT EVOLUTION ,ADAPTIVE RADIATION, SEQUENTAL EVOLUTION, PHYLETIC GRADUALISM, PUNTUATED EQUILIBRIUM.

9. Warm up part II: What do you notice. What do you think it means
Warm up part II: What do you notice? What do you think it means? Guiding questions on warm up hand out:

10. Evolution Evidence
Activity #217: Common ancestry of Life. ( the tree of Evolution)
Homework:
Activity #218 The Fossil Record: look at and discuss as a class.
We will skip Activity # 219
Activity #220: read, highlight, annotate.

11. Classification of Life: S: 1:00; F 3:30 https://www.youtube.com/watch?v=tYL_8gv7RiE&feature=youtu.be

12. (LUCA) Lowest Common Universal Ancestor
LUCA is short for Last Universal Common Ancestor, and it is from this organism that every living cell on the planet has descended. LUCA does not represent the earliest stage in the evolution of life — it is widely accepted that before the evolution of proteins and DNA (which are common to all cellular life) there was a period where RNA carried out the roles now performed by proteins and DNA
