Charles Darwin

Charles Darwin's book, 'On the Origin of Species', introduced the theory of evolution, suggesting that all living things evolved naturally over billions of years. Inspired by his voyage on the HMS Beagle, Darwin observed finches on the Galapagos Islands, noting their beak adaptations to different food sources. This led to his concept of natural selection, where species better adapted to their environment survive and reproduce. Despite initial controversy, Darwin's ideas have profoundly influenced our understanding of life's origins.

What was the main reason Charles Darwin delayed publishing his book 'On the Origin of Species'?

• He was busy with other projects.

• He wanted to gather more evidence.

• He feared the public's reaction.

• He was unsure of his findings.

During his voyage on the HMS Beagle, what did Darwin observe about the finches on the Galapagos Islands?

• They had different beak shapes suited to their food sources.

• They were all the same species.

• They all had the same beak shape.

• They migrated frequently between islands.

How did the finches on the Galapagos Islands adapt to their environment according to Darwin?

• By migrating to other islands.

• By developing different beak shapes.

• By becoming nocturnal.

• By changing their diet.

What concept did Darwin introduce to explain the evolution of species over time?

• Genetic mutation

• Natural selection

• Artificial selection

• Spontaneous generation

What was the broader implication of Darwin's theory of natural selection?

• It suggested that evolution occurs only in birds.

• It proved the existence of a single species.

• It explained the origin of all life forms.

• It denied the existence of microorganisms.
