Descent with modification. This is what Darwin called evolution.
Charles Darwin
He mainly studied birds; finches were the main ones he studied.
The ideas of descent with modification are based on fossils and the modern organisms he found basically says that genetic changes are inherited by later generations.
The structural and biochemical similarities among living organisms are best explained by Darwin's conclusion: Living organisms evolved through a gradual modification of earlier forms --- descent from a common ancestor.
he studied finches iguanas and tortoises. :)
