Why do humans not have wings?
Humans do not have wings because in their evolutionary history, they used their limbs for other purposes besides flying. The ancestral tetrapod (the group that contains amphibians, reptiles, birds and mammals) had four limbs and between the Devonian and the mid-Cenozoic era, our ancestors used all four limbs for walking. When monkeys appeared their front two limbs became modified for grasping the tree branches, and apes initiated a type of locomotion called brachiation (swinging under the tree branches with their forelimbs). There was no need to learn to fly and most apes and even monkeys were heavier and more solid-boned than most of the animals that did fly at that time. When people descended to the ground their hands became modified for grasping. Birds, bats and pterosaurs all use or used their forelimbs for flying, which meant their forelimbs had little or no grasping ability. However, they could compensate for this by entering other types of ecological niches.Humans do not have wings like birds, bats, and such because they were not created as such by their Maker. There's a reason and purpose for everything, though questions may not be answered until near death or after. The "Why?"s are meant to be reversed and satisfied; reality is meant for contentment.

What are examples of cultural materialism?
Cultural materialism is an approach that divides a culture into 3 layers: infrastructure, structure, and superstructure. Infrastructure is how people attend to their basic needs of survival and reproduction. Structure is how these strategies are managed at the level of the household and society (i.e. institutions and laws). Superstructure is the ideology that keeps the wheels of the other two levels going (i.e. the beliefs, values, art, etc.). For cultural materialists, the level of infrastructure is the most important determining factor in the form a society will take. A classic example is the protection of sacred cows in India. Although many of us might see these cows as a valuable food source, for the adaptive strategy of agriculture, cows are more useful for their labor in the fields. When the infrastructure changes (people adopted agriculture), the superstructure also changed (a new belief in the sacredness of cows) to facilitate practices that support the community's economic viability.
