520			_a"One of the most majestic creatures in the ocean is the humpback whale (megaptera novaeangliae). like all ocean whales, humpbacks evolved from a land mammal; an ancestor of modern cows and camels that returned to the ocean around 40 million years ago. Since that time, humpbacks have evolved to be an important component of the marine ecosystem. Not only has their physiology to allow them to move gracefully and rapidly in the cold marine environment, but their senses are well adapted to a life spent underwater. Scientist have determined that there are 14 distinct populations of humpbacks in the wild, each with its own preferred spring and winter feeding grounds. Through detailed studies, marine biologists now know that some populations of humpbacks may migrate up to 11,000 miles in search of their diet of plankton, crustaceans (namely krill), and even small fish. They are also known for their songs, specifically the mating songs of the males, which may be heard up to 30 miles away. The humpback whale, like many ocean species, faces a number of threats. Not only are global changes in the ocean, such as climate change and ocean acidification, negatively influencing the food chain that the humpback depends upon, but other human activities, namely pollution and hunting have endangered some of the humpback populations. Yet, humpbacks actually represent a success story for the science community. Due to careful regulations and awareness of the importance of the species, many of the humpback populations are now stable, or even increasing, in number. In this text, we will focus on these same three themes of science: Evolution; Nature of science; Biological systems. These themes form a thread that connects the content of the chapters together, and thus helps students visualize how the science of biology is interconnected at a variety of levels. The themes are supplemented by unit-level learning outcomes and a variety of digital assets to emphasize the fundamental principles of biological science, and make the content relevant to the student."--Back cover
