			Oxygen as an evolutionary constraint - November 2009 It's now clear that humans have dramatically changed Earth's atmosphere. More than 30 years ago, scientists realized that our production of chlorofluorocarbons was destroying Earth's protective ozone layer; as we burn fossil fuels for energy, we inadvertently release chemicals like sulfur dioxide, which react with other atmospheric compounds and end up acidifying rainwater; and of course, our production of greenhouse gases, like carbon dioxide, is shifting the makeup of Earth's atmosphere in a direction that actually changes the climate on a global scale. Many of our recent Evo in the News stories have chronicled how human-caused changes in Earth's atmospheric chemistry and environment are affecting the evolution of life on earth ...

Ancient fossils and modern climate change: The work of Jennifer McElwain This research profile examines how scientist Jennifer McElwain studies plant evolution in order to understand the history and patterns of global climate change.				Angling for evolutionary answers: The work of David O. Conover This research profile examines how scientist David O. Conover studies the impact of fishing practices on fish evolution and investigates why the "big ones" simply don't exist anymore.
Phylogenetic systematics, a.k.a. evolutionary trees All life on Earth is united by evolutionary history; we are all evolutionary cousins — twigs on the tree of life. Phylogenetic systematics is the formal name for the field within biology that reconstructs evolutionary history and studies the patterns of relationships among organisms.
