The history of life: looking at the patterns
The central ideas of evolution are that life has a history it has changed
over time and that different species share common ancestors.
Here, you can explore how evolutionary change and evolutionary relationships are
represented in "family trees," how these trees are constructed, and how
this knowledge affects biological classification. You will also find a timeline of
evolutionary history and information on some specific events in the history of life:
human evolution and the origin of life.
