The film discusses the characteristics and classifications of chordates, a group of animals that includes vertebrates and some simpler forms. Key features of chordates include a pharyngeal breathing ...

Charles Darwin proposed that evolution is driven by gradual variations in organisms that have a survival advantage in a changing environment. But University of Maryland evolutionary biologist Karen ...

Scientists reveal clues about the evolutionary origin of jaws by studying the embryonic development of zebrafish -- an approach known as 'evo-devo.' Using imaging and cell tracing techniques in ...
