Natural Selection in Newts

Miss Annie welcomes students to a lesson on natural selection, focusing on adaptive traits in newts. She outlines the materials needed, including histograms and other resources. The lesson examines changes in the rough-skinned newt population over 50 generations, highlighting the shift from low to high poison levels.

Who is the teacher presenting the lesson?

• Miss Annie Jarred

• Miss Alaskey

• Mr. Smith

• Mrs. Johnson

What is one of the optional resources suggested for the lesson?

• A calculator

• A family member or friend

• A science textbook

• A dictionary

What is the main focus of the lesson on natural selection?

• Evolution of birds

• Plant growth

• Adaptive traits

• Climate change

What does the histogram on the left show about the rough-skinned newts?

• Their poison levels

• Their habitat

• Their size

• Their diet

How would you describe the distribution of traits in the newt population 50 generations ago?

• No poison

• Equal high and low poison

• Mostly low poison

• Mostly high poison

What change is observed in the newt population today compared to 50 generations ago?

• No change

• More low poison newts

• More high poison newts

• Decrease in newt population

What is the significance of the high poison level in newts today?

• It makes them more vulnerable

• It helps them survive better

• It reduces their lifespan

• It has no effect

What is the purpose of discussing the histogram in the lesson?

• To show the newt's diet

• To discuss climate effects

• To illustrate changes in adaptive traits

• To compare different species

What is the main topic of the lesson?

• Natural disasters

• Human evolution

• Animal behavior

• Natural selection

What is the role of the histogram in understanding natural selection?

• It highlights the change in adaptive traits over generations

• It shows the newt's migration patterns

• It measures the newt's growth rate

• It displays the newt's feeding habits
