Investigator and Scientific Director Robb Krumlauf, Ph.D. and colleagues show that the sea lamprey Petromyzon marinus, a survivor of ancient jawless vertebrates, exhibits a pattern of gene expression that is reminiscent of its jawed cousins, who evolved much, much later.

About 400 million years ago a group of fish began exploring land and evolved into tetrapods – today's amphibians, reptiles, birds, and mammals. But just how these ancient fish used their fishy bodies and fins in a terrestrial environment and what evolutionary processes were at play remain scientific mysteries.

International Scientific Team Criticizes Adoption of 'Novel Ecosystems' by Policymakers

Novel ecosystems arise when human activities transform biological communities through species invasions and environmental change. They are seemingly ubiquitous, and thus many policymakers and ecologists argue for them to be accepted as the "new normal"—an idea the researchers say is a bad one.

Study Traces Evolutionary Origins of Migration in New World Birds

Scientists from the University of Chicago have developed a new method to reveal the ancestral ranges of New World birds, and discovered that bird migration in the Americas evolved in species that resided in North America. Their work also offers evidence that many tropical bird species descended from migratory ancestors that lost migration.

A new study led by an Australian scientist has revealed how massive, meat-eating, ground-dwelling dinosaurs − the theropods − evolved into agile flyers: they just kept shrinking and shrinking, for over 50 million years.
