What’s That Fossil? Check the Online Guide

What’s That Fossil? Check the Online Guide

In her youth, Dr. Alycia Stigall, Professor of Geological Sciences, made do with A Golden Guide to Fossils, but she hopes that today’s amateur fossil collectors and researchers will have at their disposal a more comprehensive guide. That’s why she and her colleagues are creating an online database—the Digital Atlas […]

Protect the Arctic Fox Instead of the Polar Bear?

The Kallmeyer Collection of the Ohio University Invertebrate Paleontology Collections includes invasive species that dominated the ancient landscape of Cincinnati, Ohio. The invaders include brachiopods, gastropods, bivalves, and corals. (Photo by Ben Siegel.)

Third in a series on macro-evolution. In this article, Dr. Alycia Stigall discusses the fossil record of species biodiversity—and why it might be more important to protect “intermediate” species like the Arctic Fox than “specialist” species like the Polar Bear. By Sara LaJeunesse From Perspectives Billions lie dead on the […]

Macro-Evolution: The Case of the Late Devonian Biodiversity Crisis

Macro-Evolution: The Case of the Late Devonian Biodiversity Crisis

Second in a Series on Macro-Evolution Using the fossil record—and specifically a case of mass extinction about 374 million years ago—can help illuminate why “modern” macro-evolutionary theory is in need of modernization. Darwin and his successors wrote the first chapters on evolution by looking at small changes in species over […]

It’s Time for a New Big Picture on Evolutionary Theory

First in a Series on Macro-Evolution Darwin and his successors wrote the first chapters on evolution by looking at small changes in species over relatively short periods of time, usually described as natural selection. Scientists developed the Modern Synthesis to describe gradual evolution following the discovery of the DNA molecule, […]
