Which of the following geologic and biologic events defined the Carboniferous period?   The age of the dinosaurs, lush vegetation, and abundant ferns. Birds first appeared and Pangaea broke apart.   Modern humans evolved and a major extinction event was ongoing.   The Earth thawed, allowing for an explosion of animal diversity. Most major groups of animals arose in the resultant oceans. which were dominated by trilobites and shelled organisms.   High atmospheric oxygen levels fostered giant arthropods and spore-forming plants such as lycophyte trees dominated.

Marine Evolution

Marine habitat is less explored, and hence, its biological diversity is far less known. The marine habitats are not constant due to their shifting nature, while the terrestrial habitats are more stable. Marine biology is the science that deals with the study of diverse marine species, their interactions, and behavioral characteristics.
