Opening Activity: June 5, 2017 Choose your own seats today. Pick up Giant Packet at front table. Put your name on it, review upcoming dates and put into your phone/planner. Fill out the following on blank spot on the right of the “important date” box. Student Choice – what should we do in class on Monday June 26th? I can… Explain and share your current ideas on ecology and evolution Homework: Check source, get your notebooks in ASAP!

Ecology & Evolution Initial Ideas

Lab #21 Evodots We reviewed what the simulation would look like and completed page 3 in class.

Opening Activity: June 6, 2017 Grab a computer to work in groups of two today. In what ways will our “prey” vary today? If a long beak trait is heritable, what would you expect of the offspring? How will you eat your prey today? I can… Explain how traits in a population can change over time. Homework: Check source, get your notebooks in ASAP!

Today’s tasks Work through Lab #22 Evodots and answer questions. #13 refers to “A”, this is your prediction in #4. Mechanisms of Evolution Reading, answer on page 10, lots of space on bottom: Highlight Vocabulary Words – define 3 In your own words, describe what “survival of the fittest” means. Why is the term “survival of the fittest” misleading? Explain natural selection from the perspective of the traits that are undesirable. Explain what needs to be present in a population for a population to change over time.

Opening Activity: June 7, 2017 Reflect on section 2 from lab yesterday: What happened and why? If you have not done so already, read Mechanisms of Evolution. Follow the directions from the handout at your table. I can… Explain how traits in a population can change over time. Homework: Check source, get your notebooks in ASAP! Unsupervised due 6/12

Opening Activity: June 8, 2017 I will stamp your HW – filling out the Natural Selection Grid on page 7. Read through the “Is it Natural Selection, or Not?” on page 7, circle and explain. I can… Examine different lines of evidence for evolution. Homework: Check source, get your notebooks in ASAP! Unsupervised due 6/12

Is it Natural Selection, or NOT?

Opening Activity: June 9, 2017 I will stamp Natural Selection work on page 7. Which of the following observations was NOT made by Darwin (key pts in natural selection)? Individuals in a population vary Natural resources are limited Most populations vary in size All species can reproduce successfully I can… Examine different lines of evidence for evolution. Homework: Check source, get your notebooks in ASAP! Unsupervised due 6/12

Lab #22 Evidence for Change across Time Research scientific evidence to support our claim: Populations of organisms change over time. 2. How to Research: Reach through evidence in your packet. Use online tools when necessary Answer questions on page 8 OR on the evidence pages (pgs 9-11) Construct an explanation on page 12 using at least 4 pieces of evidence to defend your ideas.

Evidence for Evolution Molecular Biology – DNA The more similar two organisms’ DNA are, the more likely they are related. They came from a common ancestor.

Evidence for Evolution 5. Fossil Record Fossils across continents Same species appear to have lived on multiple continents Fossils shows gradual changes throughout time of structures Stratification – Fossil age determined by where it is found in sediment

Evidence for Evolution 6. Comparative Anatomy Homologous Structures - Wings, hands, feet of different species have almost identical structures.

Evidence for Evolution 7. Comparative Anatomy Vestigial Structures - Structures that seem to do nothing for the species, but are important in similar species

Evidence for Evolution 8. Embryology – The study of developmental stages Make observations as you watch the following clips – what is similar? What is different? Human Development, start at 1:15 Chick development Zebrafish Development   

Evidence for Evolution 8. Embryology The study of developmental stages – Vertebrate embryos that have the same developmental pattern are more closely related.

Evidence for Evolution 9. Phylogenetic Trees or Cladograms Illustrate evolutionary relationships based on shared inherited characteristics.
