Evolution Simulations

Since evolution cannot occur before our eyes in a class period, today we’ll be ‘simulating’ evolution with a game and a simulator. For each, their are directions and questions you must answer. Click the image below to be taken to the weblink. (*iPad users: You must download and use the Puffin web browser to run these simulations)

Who Wants to Live a Million Years

Million

Choose variations in a population to try to survive for a million years. Watch out for environmental changes and mutations!

Evolution Simulation

Simulation

Watch how small changes in populations can have big impacts. You can also change settings to see how these animals would fair when their food source behaves differently.

Theories of Evolution

That’s what we’ve been talking about the last few days. We’ve talked about theories and evidence that supports or refutes those theories. There have been lots of theories of evolution but we’ve focused on two…

  1. Jean-Baptiste Lamarck

    • Acquired Characteristics
    • Whatever traits or habits that you picked up over your life, you passed on to your children.
    • Believed that if you really “needed” something or some habit to survive you could acquire it.

  1. Charles Darwin

    • Descent with Modification – Present living beings are modified decendents of older organisms and species.
    • Modification by Natural Selection – Environment limits the growth of populations. Some Organisms have traits that make them better able to survive in their environment

Evidence suggests that Drawin’s theory, which he illustrated in his book “On the Origin of Species”, is accurate. Can you think of any instances of organisms that look like other species but have some type of special advantages to help them survive in their environment?

Evolution Simulation

Sorry I can’t be there today. But I’ve got two great activities for you while I’m gone.

First, do the Darwin “Scenarios” activity with the people at your table.

Then, in our previous class we played a game using Darwin’s theory of Natural selection to see if we could help a fictional species last for a million years. There were environmental factors that influenced change, and ways of adding variation to a population.

Now we can take what we have learned and actually apply it to a real evolution simulation. We obviously cannot make evolution happen in a lab, but we can simulate it using Darwin’s theory. Click the link below (iPad users must be in the Puffin browser, not Safari) to be taken to the simulation. Read the directions, follow the procedure I have provided, collect your data, and graph your results.

Evolution Review!

Greetings from the campus of THE Ohio State University in beautiful Columbus, Ohio! That’s where I’ll be today. But I believe you’ll do a great job without me today. You’ve done a great job with the graphic organizers and it’s amazing to see how much content yo have picked up and recalled because of it! It’s a lot to cover but you’ve done it and done it well. Today I’d like you to:

  • Finish your illustrations
  • Add as much information to your board as you can (keep it neat and near the topic on the organizer)
  • Complete your video and email it to me(time-lapse or narrated). You may want to add background music for effect.
  • Complete the info-search you picked up in the front of the room (you can do it by yourself, with your table, or as a class… your choice)

Use the graphic organizer you created on Monday as a study guide this weekend. Remember you Unit 9 Group test is the first day back from Easter break, Tuesday the 29th! It will be some multiple choice but mostly fill-in and short answer. Have a great Easter!

Who Wants to Live a Million Years?

Since evolution cannot occur before our eyes in a class period, today we’ll be ‘simulating’ evolution with a game called “Who Wants to Live a Million Years?”. There are directions and questions you must answer when you play. Those can be found using this link. Click the image or one of the links below to be taken to the game. (*iPad users: You must download and use the Puffin web browser to run these simulations)

Evidence of Evolution

Evidence of Evolution PDF

The images below show different types of evidence that prove Natural Selection is the driving force behind evolution. Use these images, information rom your iBook, and the web to create answers to my questions and learn more about the evidence of Natural Selection. For an added challenge, see if you can match the name of the evidence to it’s illustration (Mouse over the images to see the answer):

Analogous Structure, Homologous Structure, Vestigial Structure, Embryology, Amino Acid  (DNA) Sequence, Divergent Evolution, Convergent Evolution, Coevolution, Gradualism, Punctuated Equilibrium, Artificial Selection, Sexual Selection, Founder Effect, Directional Selection, Disruptive Selection, Stabilizing Selection

22_17HomologousForelimbs-L

Why do all of these DIFFERENT animals have the SAME bones?

aasequence_primates

Who do we SHARE the most DNA with? What does this mean about our Evolution?

analogous

Why do these DIFFERENT types of animals have the SAME feature? Does this mean that they are closely related? or does it mean that the trait they share is an advantage in their environment?

artificial

If Humans choose the traits they want plants or animals to have is it still natural selection?

convergent-evolution-marine-all-about-reptiles-com

Why do these DIFFERENT types of animals look so SIMILAR? Does this mean they are closely related? What do Analogous structures have to do with this type of evolution?

divergent_generic

So there was a large population with many variations… but they separated from one another over time…

divergent

Are these 2 new species of butterflies or still the same? What will happen over millions of years, will they look more similar or more different?

founder

How come only one individual had a red star in the original population, but almost half have one in the new/resulting population?

gene_conservation_med

Why do humans share more DNA with Mice than chickens? What does this tell us about our evolution?

whale-vestigial-structure

Whales have legs??? What does this information tell you about Whale ancestors? where did they live? What has happened to the legs over millions of years and why did this happen? Can you think of any human examples of this?

types of selection

Directional means the POPULATION mean will move toward one extreme.
Stabilizing means the POPULATION mean will move more toward the average.
Disruptive means the POPULATION will have two extremes that have large groups and less in the average. What will happen to this population over time?

vertebrate-embryos

Why do human embryos look so similar to fish embryos??? Does this mean we’re related to fish?

peacock_display

does this display help the peacock survive in its environment? or is it just for the ladies?

puncgrad

Compare the two types of evolution… Which one says that catastrophic events cause major changes in the population? How would you describe the other?

hummingbird

Do you think this plant always had flowers perfectly suited to a hummingbird’s beak?
