These include lighter bones, higher metabolism, excretion of uric acid, and others. These are evolutionary adaptations, but it is often observed that the organisms adapt according to their environment and habits.

Question

adapted from What Is That Bird?by the U.S. Fish and Wildlife Service The first step in bird identification is learning to observe. Watch, listen, and record your observations in a journal using descriptive words and sketches, or photograph birds to capture a permanent, detailed image that you can study later. If you are just starting to watch birds, consider familiarizing yourself with the ones that you see daily. What are their general characteristics? Are they big or small, colorful or drab? Do they sit still or flit from branch to branch? Then, try comparing new birds that you see with the common birds that you already know. Is your new discovery the size of a sparrow, a robin, or a crow? Is its bill short or long, hooked or straight? Learning the basic form and structure, or morphology, of a bird will help you to make comparisons of birds. Concentrate on the shape and size of the beak, including the relative size of the upper and lower beak; length of the outer tail…

All primates have two eyes that face forward. This includes humans. Having two eyes is an evolutionary advantage and provides binocular vision, which means that two eyes are involved in the visual process. One of the advantages of having two eyes is the ability to perceive depth. Depth perception is achieved by?
