Natural Selection

• I can tell the difference between natural selection & artificial selection

• I can list the criteria that is necessary for Natural Selection to happen

• I can identify different types of adaptations

• I can describe a specific way an organism has adapted to be successful in its environment

Add important information that should be added to your notes will be marked with a sticker ->

1. Variation

2. Heredity

3. Limited Resources

4. Successful Traits

​

Parts of Natural Selection

• A feature or behavior that helps an organism survive

• Traits: neck length, beak shape

• The Point: organisms with favorable traits have a better chance of getting resources they need

Let's give specifics on the three types of Adaptations!

• What? A PHYSICAL feature that developed over time that helps an organism survive

• Example: Narrow beak can probe in the sane for insects

• Example: Long legs can walk through deep snow

• Example: Sharp teeth for tearing apart prey

• Linked to: a type of structural adaptation

• What? blending in with the environment

• How? Sneaking up on prey or hiding from a predator

What? An organism resembling another organism in order to provide protection

Their appearance gives the organism a way to use another species adaptions, indirectly.

How an organism acts can allow it a better chance to survive

• Learned - through experience, organism gained adaptation

• Instinctive - organism was born with the adaptation (innate). Can be reflex or instinct

• Learned cannot be passed on to the next generation like Instinctive

• Example: A lizard gets sick after eating a poisonous insect, the lizard avoids that type of insect in the future

Organism can perform special functions WITHIN the body

• Chemical = make poison for Snakes venom

• Internal Structures = Camel Humps

• I can tell the difference between natural selection & artificial selection

• I can list the criteria that is necessary for Natural Selection to happen

• I can identify different types of adaptations

• I can describe a specific way an organism has adapted to be successful in its environment

• If you didn't get a score of at least 70%, try the slide show again.

• Species #5 research - use a Website or AI

• How does that organism show signs of natural selection? Determine three types of adaptations they have to be successful.
