Formation and Uses of Shark Tooth Fossils
By: Nicolas McGregor
A shark tooth fossil is more than just a relic of evolution. Traditionally used as tools and as decoration, how are these fossils formed and what else are they used for? more...
Dinosaurs Smaller than Thought
In: Dinosaurs
By: Rupert Taylor
Scientists have found a glitch in equations used to calculate the weight of gigantic dinosaurs such as Diplodocus. more...
In: Evolution

In: Paleozoology
By: Ann Burnett
In 1969, a young paeleontologist, Dr Rod Wells, and his team broke through into a new section of the Victoria Cave at Naracoorte. What he found there changed his life. more...
Charles Darwin and His Theory of Evolution
In: Evolution
By: Dennis Holley
Darwin's book, "Origin of Species", became the cornerstone of modern evolutionary theory. What are the main components of Darwin's grand theory of evolution? more...
A Short History of Evolutionary Theory
In: Evolution
By: Dennis Holley
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
In: 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...

Comparative Anatomy as Evidence of Evolution
In: 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
In: Evolution
