Extinction risks for natural populations of endangered species are likely being underestimated by as much as 100-fold because of a mathematical "misdiagnosis," according to a new study led by a University of Colorado at Boulder researcher.
Assistant Professor Brett Melbourne of CU-Boulder’s ecology and evolutionary biology department said current mathematical models used to determine extinction threat, […]

Research identifies the reason humor is common to all human societies, its fundamental role in the evolution of homo sapiens and its continuing importance in the cognitive development of infants
A new publication answers centuries’ old questions regarding the mechanism and function of humor, identifying the reason humor is common to all human societies, its fundamental […]

An international consortium of scientists, led by Washington University School of Medicine in St. Louis, has decoded the genome of the platypus, showing that the animal’s peculiar mix of features is reflected in its DNA. An analysis of the genome, published today in the journal Nature, can help scientists piece together a more complete picture […]

Putting more meat on the theory that dinosaurs’ closest living relatives are modern-day birds, molecular analysis of a shred of 68-million-year-old Tyrannosaurus rex protein — along with that of 21 modern species — confirms that dinosaurs share common ancestry with chickens, ostriches, and to a lesser extent, alligators.
The work, published this week in the journal […]

Evolution has taken another step away from being dismissed as “a theory” in the classroom, thanks to a new paper published this week in the online open-access journal PLoS Biology. The research article, by Brian Paegel and Gerald Joyce of The Scripps Research Institute, California, documents the automation of evolution: they have produced a computer-controlled […]

The growing strength of the movement to discredit evolution and promote the teaching of intelligent design and other non science-based views of biological diversity in public science classrooms is of great concern. Please see the UCS position statement on this alarming trend. UCS has not developed a comprehensive program or set of actions on this […]
