Inquiry Activity You will analyze three samples of evidence for evolution We have not taken notes on these types of evidence yet, so you may not know the right answer and THAT’S OKAY! Talk with your group and use critical thinking to hypothesize how each piece of evidence could support the theory of evolution Answer the questions for each sample
How to Set Up Your Paper Sample A Answer Sample B Sample C
Inquiry Activity Expectations Do not leave your group Talk using scholar voices only with your group members Try your best even if you aren’t sure Work with urgency! 20 minutes End
Evidence for Evolution 1. Fossil Record 2. Comparative Anatomy 3. Comparative Embryology 4. Biogeography 5. Molecular Biology 6. Observed Evolutionary Change
Evidence of Evolution: 4. Biogeography
Shows geographic distribution of living species Shows how similar organisms evolved to have traits to suit environment
5. Molecular Biology Comparing DNA & protein structure everyone uses the same genetic code! DNA Who are humans most similar to? Add how we will be in the future. Why we want to know who is closest to us for disease and biology studies. *Amino acid sequence similarities among 13 vertebrate species (in %) 10
6. Observed Evolutionary Change Evolutionary change that happens quickly enough for humans to actually be able to see it Drug resistant bacteria 11
Have we observed this?
NAME THAT EVIDENCE!!!
Cladogram Cladogram: chart to diagram evolutionary relationships
Inquiry Activity Review!!! Sample A Biogeography Long noses, claws They need long noses and claws to hunt and dig for insects to eat They may have different adaptations because of the environment they live in which causes them to look different
Inquiry Activity Review!!! Sample B Molecular Biology D=1, B=2, E=3, A=4, C=5, G=6, F=7 Organism 1 is most closely related to humans The species have changed over time and adapted to different environments
Inquiry Activity Review!!! Sample C This shows that the moth species changed in order to survive the changing environment The change in tree color made it so that dark moths were better able to survive The moth population might go back to the light color. The light colored moths would have a better chance of survival if the trees are no longer dark.
Big Idea: Bacterial Resistance https://www.youtube.com/watch?v=s88jFJSRvRI Turn and Talk—how does this give evidence for the theory of evolution?
Summary Table
Notebook Output It is February of 2016 and a bacterial infection called Bull Fever spreads rapidly through the student body of Miami Northwestern. Medical magnet students have developed medicine to prevent Bull Fever and all students are given the medicine. However, after a few weeks, the Bull Fever bacteria breaks out again and is now resistant to the medicine. 1. What kind of evidence of evolution is this? 2. How does this scenario demonstrate evolution?
