This was the first animal Charles Darwin began to observe.

Evolution happens through this process.
Natural selection.
100
When species change over time to be better adapted to their environment.
Evolution
200
A person who studies plants and animals.

The years he traveled collecting information he saw.
5 years

Besides animals and plants, Darwin also observed these two natural disasters.
Volcanoes and earthquakes
200
The idea of humans altering the characteristics of plants and animals.
Artificial selection
200
Why finches have different shaped beaks.
To eat different foods found on specific islands

Was known as the "father of _________".
Evolution

The purpose of Darwin's expedition.
To observe and study different species of plant and animal life.

Charles Darwin's work was influenced by this man.
Charles Lyell

Darwin believed that these two things affected natural selection.
Overpopulation and competition
300
Certain parts of animals that change over time.

His most famous book.

Charles Darwin kept this to record his findings.
The Journal of Researches.
400
Charles discovered this idea that the birds on the different islands had differently shaped beaks to adapt to new foods.
Natural selection
400
This can occur because of natural selection, when a species no longer exists in the world.
Extinction
400
How have cacti evolved to survive the hot desert habitats?
Growing spines instead of leaves
500
This was the age he began his expedition around the world observing plant and animal species.
22 years old

These formed the Galapagos Islands.
Volcanoes
500
The idea that organisms were transported to the islands from the mainland, and then began to slowly change which developed them into different species.
Transmutation.
500
When a species is adapted better to survive.
Competition
500
Darwin's theory of evolution upset this group of people.
