1 HAPPY WEDNESDAY Bellwork: Draw the organisms below and explain how do you know where the organisms live.

2 2 nd Semester To-Do List CHAMPS Cell Phones/Headphones Required Materials – Kleenex – Notecards

3 Take a few minutes and copy this word map into your notes. Evidence of Evolution Fossil Record Embryonic Molecular Anatomical Homologies = SAME Biogeography

4 The word Homologies refers to similarities among organisms HOMO = SAME There are three types of homologies that provide strong evidence for evolution and common ancestry

5 Take a few minutes and copy this word map into your notes. Evidence of Evolution Fossil Record Embryonic Molecular Anatomical Homologies Biogeography

6 3. Anatomical Homologies: bones and muscles of different species that have similar structures but perform different functions

8 Take a few minutes and copy this word map into your notes. Evidence of Evolution Fossil Record Embryonic Molecular Anatomical Homologies Biogeography

9 2. Embryonic Homologies: Different organisms develop from similar starting forms (embryos)

10 4. Embryonic Homologies: Different organisms develop from similar starting forms (embryos)

12 Take a few minutes and copy this word map into your notes. Evidence of Evolution Fossil Record Embryonic Molecular Anatomical Homologies Biogeography

13 1. Molecular Homologies: similarities in DNA sequences among different organisms Because organisms evolved from a common ancestor, we find similarities in the DNA sequence of all living organisms. The more of a DNA match we see, the closer of a relationship the organisms have.

14 The chart below compares the base sequences of homologous segments of DNA from various primates. Based on this data, which primate is the least closely related to humans?

15 Homework tonight: Cladograms by Bozeman Science Cornell Notes plus you MUST draw the cladogram

16 Periods 4 & 5 HW: Cladograms Search for the YouTube video “Cladograms”Cladograms by Bozeman Science. Periods 4 & 5: Complete on Page 49 of your I.A.N. using Cornell Notes. Due TOMORROW. https://www.youtube.com/watch?v=ouZ9zEkxGWg

17 A. Copy ONE of Mr. Anderson’s cladograms below: B. Draw an arrow on your cladogram to show TIME. C. Answer the following questions about your cladogram: 1. Which two organisms are the most closely related? 2. Which two organisms are the least closely related? 3. Which branch represents the most recent (youngest) organism? 4. Which branch represents the oldest organisms? 5. What do the branching points represent (where two branches go in different directions)?
