How is this best explained? the gibbons and siamangs of Southeast Asia, are still separated into their own family, the Hylobatidae. Figure 18.1 C. 1: Darwin's Finches: Darwin observed that beak shape varies among finch species. Many generations later, almost all ducks had more webbing on their feet. As hominins, or bipedal apes, came to rely less on an arboreal environment, the bones of our ancestors hands and some foot bonesbecame shorter and straighter and our legs became longer and more efficient for covering long distances on African landscapes. Because an idle floating duck or a duck squatting on land cannot react to fly or move quickly, "a sitting duck" has come to mean "an easy target". A mutation occurred to a flower. Their body is designed in a different way. Duck eggs are slightly more nutritious than chicken eggs.

Mother ducks are very caring and protective of their young, but may abandon some of their ducklings if they are physically stuck in an area they cannot get out of (such as nesting in an enclosed courtyard) or are not prospering due to genetic defects or sickness brought about by hypothermia, starvation, or disease.
