known as the "Father of Evolution" author of "On Origin of Species." The first person to describe Natural Selection
Before Darwin, recognized that species change over time, but thought the mechanism was acquired traits which could be passed onto offspring.

any fossilized remains of a life form that exhibits traits common to both an ancestral group and its derived descendant group.
Is the system used to organize all life on Earth. This system allows scientists to examine the relationships between various organisms and to construct evolutionary trees to explore the origin of life.
