specimen of various organisms on his travels
Came up with the theory of Natural Selection
Published his findings in a book titled The Origin of the Species

Charles DarwinCharles DarwinSuggests that the
environment shapes the organisms
Those who cannot adapt to the environment will die
Those who can adapt are able to reproduce and create more of themselves

Darwin’s FindingsDarwin’s Findings
Darwin took detailed observations of the organisms he saw
Came up with a theory that explained how they came into being
Concluded that certain organisms had traits that made them better suited to the environment
They had an advantage

From one ancestral bird, a HUGE population came into being!
The Hawaiian honey creeper is a classic example of Natural Selection
