The Holocene marks the most recent ~10,000 years of natural history, including the rise of Human civilization and the wholesale transformation of the Earths surface.

The Cenozoic Era began with the destruction of the dinosaurs, and would see the rise to dominance and wild diversification of the birds and the mammals, including the emergence of a curious primate species.

The Mesozoic Era saw the evolutionary emergence and rise to dominance of the dinosaurs, and the emergence of early bird and mammal ancestors.

The Paleozoic Era saw the rapid emergence of increasingly complex life forms that filled the sea and the land, but they would all face extinction during the events known as the Great Dying.

Life on Earth is billions of years old. This ancient natural history comes to us in the form of fossils and genetic relationships, revealing the incredible story of the evolution of life.

All populations are subject to perpetual evolution, and Humans are no exception; peer into our distant past and observe the evolutionary history of the Human species.

As all living things are fundamentally related, phylogenetics is the study of these genetic relationships, and the evolutionary history of the many diverse lineages of Earthly life.

When populations groups diverge, whether they're separated geographically, temporally, or behaviorally, they find themselves on the pathway to speciation.

Besides natural selection, evolution is influenced by mechanisms like gene flow, the random walk of genetic drift, and the novelty-generating phenomenon of genetic mutations.

The forces of natural selection remove from the gene pool those lineages too unfit to survive in a given habitat, while those with good health survive to make healthy offspring, and their lineages tend to perpetuate.
