Which of the following is probably the best explanation for the fact that Antarctic penguins cannot fly, although there is evidence that millions of years ago their ancestors could do so? Group of answer choices Penguins live on land and feed in the water; therefore they have no need to fly. The Antarctic home of penguins is flat and barren; therefore there is no place to fly. Ancestral penguins did not use their wings for long periods of time; therefore today’s penguins have only tiny, nonfunctional wings. Ancestral penguins without large wings were better able to swim and feed in the water; therefore they passed their genes for shorter

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.
