Because of selective forces, the dinosaurs were superbly adapted to their environments. After the dinosaurs became extinct, the small mammals that had been relatively unimportant animals in the background flourished and evolved into many new types, including the line that led to human beings. It is unlikely that these new types would have ever evolved had not the dinosaurs disappeared. If the extinction of the dinosaurs was caused by an extraterrestrial impact, did it matter how well they were adapted to their environment? What does this suggest about the starting cause in the evolutionary success of these new types of mammals?

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.
