Darwin's Studies and Adaptations

In this video, Rachel Hansen introduces the concept of natural selection through Darwin's observations in the Galapagos Islands. She explains how different bird beaks adapted to their food sources, leading to the theory of natural selection. The video includes a hands-on experiment simulating bird beak adaptations using household items. Students are encouraged to explore Darwin's journey through a Khan Academy activity and consider the adaptation of the coronavirus. The lesson emphasizes understanding natural selection and adaptation in various contexts.

What was the primary purpose of Charles Darwin's voyage on the Beagle?

• To find a new trade route

• To map the coastlines of South America

• To discover new species of plants

• To study the stars and planets

What did Darwin observe about the finches on the Galapagos Islands?

• They had different colored feathers

• They migrated to different islands

• They had varying beak shapes and sizes

• They sang different songs

What is the main idea behind the concept of natural selection?

• Organisms best adapted to their environment survive and reproduce

• All organisms evolve at the same rate

• The strongest organisms always survive

• Organisms choose their environment

• Tweezers

• Spoon

• Chopsticks

• Tongs

What was the outcome for the 'spoonbill bird' in the experiment?

• It thrived and reproduced

• It barely survived

• It collected only small insects

• It failed to collect any food

Which bird beak adaptation was least successful in the experiment?

• Tongs

• Spoon

• Tweezers

What example is given to show the coronavirus's ability to adapt?

• Its resistance to all vaccines

• Its ability to survive in cold climates

• Its mutation to affect big cats like tigers

What is the significance of the Beagle in Darwin's studies?

• It was the name of Darwin's first book
