WRITE ABOUT A THEME: ORGANIZATION Early tetrapodshad a sprawling gait (like that of a lizard): As the right front footmoved forward, the body twisted to the left and the left rib cageand lung were compressed; the reverse occurred with the nextstep. Normal breathing, in which both lungs expand equallywith each breath, was hindered during walking and preventedduring running. In a short essay (100–150 words), explain howthe origin of organisms such as dinosaurs, whose gait allowedthem to move without compressing their lungs, could have ledto emergent properties

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.
