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.

QUESTION 3 Darwin's theory of natural selection explains: O The way life began. O The way evolution works at the genetic level. The way dinosaurs became extinct. O That traits within a breeding population that are adaptive to specific environmental circumstances become more numerous in that population over time.

Question 5 What is the point of telling the story of how the Great Auk went extinct? Although Darwin did not think extinction occurred, the Great Auk story shows that species actually can go extinct. O Although Darwin thought extinction is caused by great catastrophes unlike anything humans have ever experienced, the Auk story shows that humans (not great catastrophes) can cause extinction. O Although Darwin thought extinction is a very slow, natural process, the inevitable side-effect of speciation, the Great Auk story shows that extinction can also occur quickly, the result of human actions. In a way, humans act as a "catastrophe."
Question 23 What is the MOST LIKELY explanation for why there is variation in aging across different species? O The strength of selection is determined by aging O Trade-offs only apply to some species O Mutation accumulation theory applies to some species while antagonistic pleiotropy applies to others O Different species suffer different levels of background (i.e., extrinsic) mortality
