Outcome I will create a fish with certain inherited traits and explain how my fish is adapted to its environment.
A Fish Story: Survival of the Fittest Part 1 • Pick one card from each container. (7 total) • Design a new fish species that contains all of the traits on the cards. • Draw the environment the fish would best survive in. • Answer the questions and glue them on your poster
A Fish Story: Survival of the Fittest Part 2 • Pick a random mutation card from your teacher. • Quickly add a mutated fish drawing to your poster. • Answer the questions and glue them on your poster.
Outcome I will create a fish with certain inherited traits and explain how my fish is adapted to its environment.
Did you know… • Your DNA is 98% identical to a chimpanzee! • Your DNA is 99.9% identical to the person sitting next to you! • We determine this relatedness by comparing DNA nucleotides
Did you know… • Species that live now are different from species in the past. We can tell this by looking at fossils. • Birds are believed to be evolved from dinosaurs! • Whales and boa constrictors have pelvic bones…but no legs!
Variation • Individuals of the same species have differenttraits
What can increase variation? • Crossing Over in Meiosis • Sexual reproduction • Mutations
Adaptation • Beneficial variation in a behavior or trait that an individual is born with. • Allows them to survive in their environment
Natural Selection • Individuals better adapted to their environment survive and reproduce more often than less well adapted individuals
What do you need for natural selection to occur? • Variation caused by mutation • Environmental pressure • Climate • Predators • Lack of resources • Selection of certain inheritable traits • Adaptation over many generations
Evolution • Change in a populationover time • Results from natural selection
Design your Butterfly • Goal: Design a butterfly that cannot be found • Grab a white sheet of paper • Design a butterfly- You decide color, size, wing shape • Hide your butterfly in the room (think about the best environment for your butterfly)
