Through a process of speciation, the movement of the continents has had a generous role throughout evolution, effecting and distributing flora and fauna.
WebContinental Drift A key to the modern distribution of a species is the site of its ancestral origin. The origin of many organisms was a puzzle until the significance of continental drift—the separation of major landmasses over geologic time—to biogeography became apparent. Pangea Adapted from C.R. Scotese, The University of Texas at Arlington WebFossil records are strong evidence that the continents do drift.

Web2 days ago · When animals voluntarily eject blood from their bodies, the act is referred to as auto-hemorrhaging. For the horned lizard, one of the primary motives to auto-hemorrhage is self-defense. Several studies have investigated how these lizards respond to different predators and threats. Hawks and snakes are a common threat to this species.
