Natural Selection and Trait Adaptation

The video tutorial by Miss Charted explores natural selection, focusing on mutations and their impact on populations. It covers adaptive and non-adaptive traits in cold environments, using a simulation to observe changes over 50 generations. The lesson encourages students to think critically about how mutations introduce new traits and their adaptiveness.

What materials are suggested for this lesson on natural selection?

• A smartphone and headphones

• A calculator and textbook

• A pencil or pen, paper, and optional family member

• A computer and internet connection

Which fur trait is considered non-adaptive in a cold environment?

• Trait 9

• Trait 7

• Trait 1

• Trait 5

What does the 'na' label indicate in the context of fur traits?

• The trait is adaptive

• The trait is dominant

• The trait is non-adaptive

• The trait is neutral

How can mutations affect a population?

• They can only introduce adaptive traits

• They can introduce both adaptive and non-adaptive traits

• They have no effect on traits

• They only remove non-adaptive traits

What is the purpose of the simulation in the lesson?

• To calculate the speed of evolution

• To model how mutations affect traits in a population

• To identify the strongest species

• To observe the extinction of species

What indicates a mutation in the simulation?

• A green dot

• A red dot

• A yellow dot

• A blue dot

Which traits were found to be adaptive after 50 generations?

• Traits 1 and 2

• Traits 3 through 9

• Traits 7 and 8

• Traits 5 and 10

What was surprising about the traits present after 50 generations?

• All traits disappeared

• Trait 10 was the most adaptive

• Traits 3 and 4 were more adaptive than expected

• Traits 1 and 2 were still present

What does the presence of traits 3 and 4 after 50 generations suggest?

• They were neutral

• They were non-adaptive

• They were dominant

• They were adaptive

Why were traits 1 and 2 considered non-adaptive?

• They were present in the final population

• They disappeared after 50 generations

• They were the most common traits

• They were the least common traits
