Amazing animals [antikvár]

mvu FOR JURVIVflLw wariety is the very If essence of animal life. The world is full of flying, crawling, and burrowing creatures. Feathered, furred, and naked, fat and lean, huge and tiny, animals exhibit every shape and behavior. Birds fly, but some can only walk or swim. Fish swim, but some climb onto land. Predators thrive by virtue of their keen eyesight, but some are blind. Yet the variety has a single purpose: What appears tobe merely strange or decorativea bizarre appendage, vivid color, or unusual markingis necessary for survival. The variety is endless, and new discoveries are made every year; although scientists are often baffled by these findings, they do know that not a feather, fiber, bone, or sinew exists that does not, or did not at one time, further life. The diversity of evolution not only enriches lifeit makes it possible.
