Concept explainers

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.

The ancestors of extant tetrapods first evolved the ability to live out of water over 350 million years ago. Which of the following had to have been true for natural selection to have favored the original evolution of limbs? A) Closely related lineages that remained in the ocean must have gone extinct. There must have been differences in survival and or/reproduction based on size, musculature, bones or other (B functional aspects of early limbs. Large predators must have been a major source of mortality for populations that spent more time in the water and less on land. The ability of some ancestral fish-tetrapod transitional forms to move from one body of water to another during D droughts must have led to decreased mortality. E There must have been less competition for food on land.
