1 DO NOW Choose one of the following and explain how that type of isolation leads to a new species: Geographic isolation Behavioral isolation Temporal isolation

2 Agenda Do Now Review Patterns for macroevolution Evidence for evolution

3 UNIT TEST: NEXT THURSDAY/FRIDAY

4 Objective I will Compare and contrast 6 patterns for evolution Analyze evidence for evolution

5 Patterns for macroevolution

6 Investigation What is happening in the two pictures? What do you think is causing this?

7 Patterns for macroevolution Divergent evolution Convergent evolution Coevolution Punctuated equilibrium Adaptive radiation Mass extinction

8 Divergent evolution Formation of new and different species from a common ancestor

9 Convergent evolution Evolution of similar features from different ancestors Why did they develop similar structures?

10 Coevolution Two (or more) species affect each other s evolution

11 Review

12 Punctuated equilibrium Rare and rapid speciation, followed by little to no evolutionary change, and so forth

13 Adaptive radiation Common ancestor evolve into multiple different species, each adapted to a different environment

14 Mass extinction Extinction of large number of species in a short amount of time Due to catastrophic global event or rapid environmental change

22 Practice Evolution in Action (1) You have 10 minutes

23 Practice Speciation Worksheet #2 You have 10 minutes

24 Homework Reading- Evidence for Evolution Due Thursday/Friday

25 WE WILL NOW SWITCH GEARS

26 POGIL ROLES Facilitator: Keeps track of time, ensures everyone is working in a timely manner Spokesperson: Communicates questions to the teacher Quality Control: Ensures all members are answering all questions together Process Analyst: Evaluates team members and generates a report

27 POGIL Take 30 seconds to determine your roles

28 POGIL Goal: Learn about evidence for evolution You have 20 minutes to complete the entire packet

29 POGIL Goal: Learn about evidence for evolution You have 40 minutes to complete the entire packet

30 DO NOW Take out your HW (2 worksheets) Glue them to your practice notebook

31 AGENDA Review Continue lesson

32 EVIDENCE FOR EVOLUTION

33 EVIDENCE FOR EVOLUTION 1. Anatomical structures (fossil records) Comparative Anatomy Homologous and analogous structures Vestigial structure 2. Comparative Embryology 3. DNA sequences (Biochemical)

34 Part of a body 1. ANATOMICAL STRUCTURES

35 FOSSIL RECORD History of life documented by fossils Fossil record represents less than 1% of all species that ever lived

36 COMPARATIVE ANATOMY Study of similarities and differences of the anatomies of different organisms

37 HOMOLOGOUS STRUCTURES Structures inherited from the same ancestor; variation in use

38 QUICK CHECK Do homologous structures arise from convergent or divergent evolution?

39 ANALOGOUS STRUCTURE Different anatomies (from different ancestors) but similar functions

40 QUICK CHECK Do analogous structures arise from convergent or divergent evolution?

41 VESTIGIAL STRUCTURE Anatomical structure that was important to an ancestor, but no longer serves a purpose

42 2. COMPARATIVE Comparing embryos of species Embryo = unborn offspring in the process of development EMBRYOLOGY

43 3. DNA SEQUENCES (BIOCHEMICAL) Comparing DNA and genes

44 EVIDENCE FOR EVOLUTION 1. Anatomical structures (fossil records) Comparative Anatomy Homologous and analogous structures Vestigial structure 2. Comparative Embryology 3. DNA sequences (biochemical)

45 SUMMARY OF NOTES Write a summary of all the notes you took today IN YOUR OWN WORDS. 2 paragraphs - 1 paragraph for the patterns of evolution, 1 paragraph for the evidence for evolution
