Existence precedes essence Sartre claimed that a central proposition of Existentialism is that existence precedes essencewhich means that the most important consideration for individuals is that they are individuals—independently acting and responsible, conscious beings "existence" —rather than what labels, roles, stereotypes, definitions, or other preconceived categories the individuals fit "essence". The actual life of the individuals is what constitutes what could be called their "true essence" instead of there being an arbitrarily attributed essence others use to define them. Thus, human beings, through their own consciousnesscreate their own values and determine a meaning to their life. His form must be just as manifold as are the opposites that he holds together.
Primates are characterized by being anatomically unspecialized, with limbs capable of performing a variety of functions, refined five-digit hands adapted for grasping including opposable thumbscomparatively flattened snouts, and prolonged pre and postnatal development, among other features.
All primates have five fingers pentadactyl that are long and inward closing, short fingernails rather than clawsand a generalized dental pattern. While opposing thumbs are a characteristic primate feature, this feature is not limited to this order; opossumsfor example, also have opposing thumbs.
Primates are omnivorous generalized feeders that consume both animal protein and vegetation. Primates are informally arranged into three groups: Humans belong to the third group of primates, and specifically those primates known as apes.
Apes are those primates placed in the superfamily Hominoidea of the same clade Catarrhini; the Old World monkeys are placed in the superfamily Cercopithecoidea in the clade, or parvorder, Catarrhini.
Apes consist of the various species of gibbons or "lesser apes"as well as gorillaschimpanzeesbonobos, orangutansand humans collectively referred to as the "great apes". From the point of view of superficial appearance, all living members of apes are tailless, while most Old World monkeys have tails.
However, there are also primates in other families that lack tails. More specifically, the apes can be distinguished from the Old World monkeys by the number of cusps on their molars apes have five—the "Y-5" molar pattern, Old World monkeys have only four in a "bilophodont" pattern. Apes have more mobile shoulder joints and arms, ribcages that are flatter front-to-back, and a shorter, less mobile spine compared to Old World monkeys.
A common taxonomic scheme divides the apes, or hominoids, into two families: The family Hylobatidae consists of 4 genera and 12 species of gibbonscollectively known as the "lesser apes" The family Hominidae consisting of gorillas, chimpanzees, orangutans, and humans, collectively known as the "great apes" Members of the family Hominidae are called hominids by many systematists.
Since recent classification schemes for the apes place extinct and extant humans, chimpanzees, gorillas, and orangutans in Hominidae, technically hominid refers to members of these groups.
However, historically and even in some current classification schemes, Hominidae is restricted to humans and their close, extinct relatives—those more similar to humans than to the other great apes, which were placed in another family.
Thus, there is a tradition, particularly in anthropologyof using the term hominid to refer only to humans and such forebears as AustralopithecusHomo habilisand Homo erectus. In this sense, humans are considered the only surviving hominids.
Based on purely biological aspects morphology, DNA, proteins, and so onit is clear the humans are primates. Indeed, humans and chimpanzees share more than 98 percent identity by various molecular comparisons protein sequences, allele differences, DNA nucleotide sequences Wood ; King and Wilson Biologists believe that the two species of chimpanzeesPan troglodytes and Pan paniscus, are the closest living evolutionary relatives to humans.
The anatomical and biochemical similarity between chimpanzees and humans is so striking that some scientists even have proposed that the two chimpanzee species be placed with sapiens in the genus Homo, rather than in Pan.
One argument for this suggested reclassification is that other species have been reclassified to belong to the same genus on the basis of less genetic similarity than that between humans and chimpanzees.
For example, Ebersberger et al.
Likewise, a comparison of a rough draft of the chimpanzee genome—involvingcontiguous fragments with a medium length of 15, nucleotides, covering about 94 percent of the chimpanzee genome—with the human genome, for those sequences that could be aligned, averaged 1.
Comparison of chimpanzee exons and human sequences yielded only 0. For a more detailed discussion of this, see Chimpanzees and humans. Uniqueness of human beings Because humans are classified as primates and because apes are considered to be our biological ancestors, there is a modern tendency to consider humans as "just another primate" or "nothing but an animal.
However, despite the remarkable physical similarity, the gulf between humans and other great apes and other animals in general is qualitatively huge, in terms of culturalpsychological including emotional and mental characteristicsand spiritual aspects. Humans have a complex language, use symbols in communication, write and read books, have set up diverse systems of governance, have remarkable self-awareness, conduct scientific experiments, practice religious traditions, have developed complex technologiesand so forth.

Dear Twitpic Community - thank you for all the wonderful photos you have taken over the years. We have now placed Twitpic in an archived state. This reader was charmed, excited and inspired by this book. "We Feel Fine" operates on several levels. Physically, it has the heft and graphic quality of a medium sized, high-end coffee table book.
Social capital. The notion of social capital is a useful way of entering into debates about civil society – and is central to the arguments of Robert Putnam and others who want to ‘reclaim public life’.
