The development of evolutionary theory is a long and convoluted tale encompassing thousands of years of time and the contribution of many individuals along the way. more...
Gene Flow as a Mechanism of Evolution
By: Dennis Holley
This planet teems with an amazing diversity of living species. How does gene flow help drive the process of evolution to produce such a riotous multitude of life? more...
Genetic Drift as a Mechanism of Evolution

The Fossil Record of Evolution
By: Dennis Holley
To hold a fossil is to touch life from the far distant past. What do bits and pieces of ancient bone and shell reveal about the types and diversity of ancient life? more...
Natural Selection as a Mechanism of Evolution

Mutation as a Mechanism of Evolution
By: Dennis Holley
This planet teems with an amazing diversity of living species. How do mutations help drive the process of evolution to produce such multitudes? more...
Comparative Anatomy as Evidence of Evolution
By: Dennis Holley
Homologous traits reveal a common ancestor but analogous traits point to convergent evolution. The challenge for evolutionary biologists is to determine the difference. more...
The Molecular Record of Evolution
By: Dennis Holley
Buried deep in the genome of every species are molecular clues to the origin and evolution of that species. more...
Small skeletons found in a cave in Indonesia may be proof that a tiny race of humans once lived in that area. more...
Homoplasies, Similar Character Traits
By: Thomas Wyatt
A homoplasy is a feature shared by different organisms that was not present in their most recent common ancestor. Homoplasies demonstrate adaptation in the living world. more...

Archaeopteryx is almost definitely a link between dinosaurs and modern birds, but there is still debate as to how - or even if - it ever flew. more...
The Late Ordovician Mass Extinction
By: Laura Wormuth
Although not well-known to the public and typically overlooked by the press, the late Ordovician mass extinction event is the most understood by paleontologists. more...
