  1. Warmup12/9/13 What is your appendix for? What do you know about that organ? Explain as best as you can. Objective Tonight’s Homework To learn how small changes affect organisms Summarize everything we’ve found so far. What seems like a good explanation for where life comes from?

  2. Notes on Evidence - Microevolution If we see something happen in a small way, it’s not impossible to think that it could happen in a big way, too. For example, let’s say you go on a diet. In the first two weeks you see great progress and lose 5 lbs. It’s not impossible to think that you could continue this pattern and lose a ton of weight over a few months.

In the first two weeks you see great progress and lose 5 lbs. It’s not impossible to think that you could continue this pattern and lose a ton of weight over a few months. This same idea gets applied to living organisms as well. We see small changes over a few hundred years. Is it impossible to believe, then, that these little changes over hundreds of years could turn one creature into another?

  4. Notes on Evidence - Microevolution This idea is called microevolution. Humans exhibit a few things along these lines as well. Wisdom teeth and the appendix appear to be useless. Maybe as humans we’re just “evolving” out of them?

  5. Notes on Evidence - Microevolution This idea is called microevolution. Humans exhibit a few things along these lines as well. Wisdom teeth and the appendix appear to be useless. Maybe as humans we’re just “evolving” out of them? This may or may not be true, but we can’t scientifically prove it. Additionally, there are a few things here we need to make sure are clear. Microevolution is not against creationism. If God chooses to let us change AFTER creation, that doesn’t violate or go against anything.

  6. Notes on Evidence - Microevolution Microevolution just changes traits that are already there or removes traits. It can’t add any new information or things to a creature.

  7. Notes on Evidence - Microevolution Microevolution just changes traits that are already there or removes traits. It can’t add any new information or things to a creature. For example, all dogs have the genetics to have long hair. Dogs that have lived near the equator for a long time though don’t have long hair because they don’t need it. But if that species of dog began migrating north, they’d slowly regain their long hair. In no way have we seen the dog “evolve”. We’re just mixing around traits that are already there.

  8. Notes on Evidence - Microevolution So what does this tell us about where life came from? All we can say is that not everything is as it looks. Just because we’re seen some creatures change in little ways now doesn’t mean they’ve changed in bigger ways in the past. This is bias again.

  9. Notes on Evidence - Microevolution Additionally, if we look at some animals, they can’t “microevolve” unless many parts evolve at the same time. In other words, for microevolution to work on a large scale, we have to have lots of parts all mutate at the same time in a way that lets them all work together. While not strictly impossible, this seems extremely unlikely. Add in the fact that this has happened not once, but apparently millions of times with thousands of species and things start sounding VERY unlikely.

  10. Notes on Evidence – Microevolution Conclusion (I want you to spend the next 10 minutes looking over these notes. Answer the following questions at the end, in a part called “conclusion”. 1) What’s the basic idea behind microevolution? 2) What can microevolution tell us about the history of a creature and what it came from? 3) Are there any other topics, questions, or data relating to any of the topics we’ve covered this week? 4) What’s your conclusion? What does the data say?

  11. Exit Question #44 What's an example of microevolution in humans? a) That some people are born without wisdom teeth b) That some people are born deformed c) That some people are born with extra teeth d) That some people are born with extra toes e) All of the above are examples of microevolution f) None of the above are examples of microevolution
