Philosophy Human nature seems to be delicately balanced between destructive and constructive forces, which may wrestle and be in continual conflict. However, it is possible to resolve the conflicts inherent in human nature to create unity and harmony. Plato pointed out that the body and the soul represent the two opposing forces pulling human nature in different directions, potentially begetting conflict. The body's appetites and desires for pleasure are pitted against the soul's desire for reason. Appetites include the most basic impulses of survival like hunger, thirst, and sex. Other aspects of human nature that can conflict include the aspect of aggression: the "spirited" nature of a human being that is not necessarily destructive but can be if not kept in check. Similarly, the body's appetites are good in the sense that they help keep the body alive, but they need to be tempered by reason to avoid problems. Generally, the main components of human nature in the Platonic conception include reason,...
When aggression and appetite are subsumed by reason, the individual can achieve harmony (Chapter 2, p. 10).
Zoology Relics of Human Evolution Vemeonasal organ. The vemeonasal organ is a little pit on each side of the septum that is lined with nonfunctioning chemoreceptors. It may have been used for pheromone-detecting ability. Extrinsic ear muscles. These three muscles most likely made it possible for prehominids to move their ears independently, in the manner of many mammals, such as rabbits and dogs. Many people can learn to wiggle their ears because of
Usually, in hotter climates that are nearer to the equator, spread will be more powerful and Malaria is spread throughout the year. The uppermost spread is initiated in Africa South of the Sahara and in fractions of Oceania such as Papua New Guinea. In less hot areas, spread will be less powerful and very cyclic. In many moderate regions, like Western Europe and the U.S. financial expansion and public
In truth, large sharks tend to hunt large blubbery prey with a much higher ratio of flesh-to-bone than human beings. That is apparently why many test bites on a human result in no further attack. In the last decade, a tourist industry has evolved in parts of the world with access to coral reefs and natural shark populations. Hand-feeding excursions allow divers, lead by more experienced professionals to encounter sharks
In Paleontology, however, these wing digits have been considered as digits 1, 2 and 3 based on phylogenetic assessment of the fossil lineage suggesting that birds have evolved from theropod ancestors that had lost the fourth and fifth digits. Critics of this theory have suggested that birds have evolved from some other ancestors that had lost the first and fifth digits. Studies of developing limbs of chicken, including a
LEECHES: Bloodsuckers, Life-And-Limb-Savers "Nothing works as well as leeches when we need to get blood out of a (body) part." Concannon). Blood clotting is a life-saving body process, but when it endangers life or prevents the resolution of a torn tissue, leeches can come in handy. They have shown their worth as natural blood thinners, painkillers and surgical scavengers with the anticoagulant and anesthetic properties of their saliva. These saliva components hold much
The authors explain that "Large-scale habitat loss and fragmentation…" that results from urban sprawl is a major cause of the lack of biodiversity within the insect species (Acharya, 1999, 27). Even the building of a new road, or street lights, in places where previously there were no roads or lights, what the authors call "undisturbed areas," has an impact on insect biodiversity, Acharya explains. Meanwhile, moths, which are known
