Evolution and Natural Selection: Insights from Galapagos

What year did Charles Darwin arrive at the Galapagos Islands?

• 1845

• 1835

• 1855

• 1865

What initially fascinated Darwin about the Galapagos Islands?

• The islands' unique bird species

• The diverse plant life

• The islands' geology

• The marine life

Which animal's shell shape intrigued Darwin and contributed to his theory?

• Finches

• Tortoises

• Sea lions

• Iguanas

How many species of Galapagos finches did Darwin's observations contribute to identifying?

• 10

• 13

• 15

• 20

What was the key feature that Darwin noticed varied among finches from different islands?

• Feather color

• Song type

• Wing span

• Beak size

What did Darwin propose was the mechanism for the development of new species?

• Adaptive radiation

• Evolution by natural selection

• Genetic mutation

• Survival of the fittest

Which plant fascinated Darwin due to its complex relationship with pollinators?

• Orchids

• Daisies

• Roses

• Sunflowers

What unique evolutionary strategy do orchids use to attract pollinators?

• Producing a scent similar to female bees

• Singing like birds

• Mimicking the appearance of predators

• Glowing in the dark

The image shows light and dark colored moths that live on a tree. Which result is most likely to occur to the moth population over time due to predation?

• The number of light colored moths in the population will increase

• There will be more dark colored moths than light colored moths

• The number of light colored moths will decrease

• The dark colored moths will move to a different type of tree

Charles Darwin studied finches in the Galapagos Islands which inspired his theory of evolution and natural selection. What did he notice about the finches that surprised him?

• They were all different colors and blended in with the flower on their own island

• They were all exactly the same regarless of what island they lived on

• The were are similar but have different beaks based on the food available on their island

• Charles Darwing has nothing to do with finches, islands, or Natural Selection
