Gauguin, Where do we come from? What are we? Where are we going?

Where Do We Come From? What Are We? Where Are We Going? is a painting by French artist Paul Gauguin. Gauguin inscribed the original French title in the upper left corner: D'ou Venons Nous / Que Sommes Nous / Ou Allons Nous. The inscription the artist wrote on his canvas has no question mark, no dash, and all words are datingusaforall.com: Paul Gauguin. Aug 10,  · Like any other animal we are multicellular creatures, mobile and obtain our energy from food. Furthermore, we have muscles, nervous systems and internal cavities where food is broken down and converted into energy. As mammals, we can regulate our body temperature, our female variety can give birth to live children and breastfeed them. However, our brain has difficulties in accepting that we .

Genre: Oil on canvas. A variety of figures, all of them Tahitian, sprawl across the wide frame of the painting, each engaged in a particular and significant act. In the center of the image, a man wearing a simple loincloth picks an apple from the top edge of the image.

To his right, a nude person examines his or her underarm, two clothed women in the background walk together with their arms around one another, three women sit together around a babe, and a dog looks inward from the exterior of the right edge.

On the left of the apple-picking afe, two white kittens play with one another next to a clothed young girl who eats an apple.

Behind her lies a goat. In the far background stands a blue religious statue, to the right of which stands a lone fully clothed woman. At the far left of the painting, a dark-skinned unclothed doo woman sits with her head in her hands, next to a seated, nubile young woman with firm, full, bare breasts.

A white bird sits to their immediate left. What Are We? Where Are We Going? WhersGauguin emigrated to Tahiti in search of a society more unspoiled than his native France. This piece, part of a series of introspective paintings inspired by his new country, was considered by Gauguin "to be his masterpiece and the summation of his ideas" see Boston Museum of Fine Arts web site. The piece should be viewed as a text from right to left--a suggestion imparted by the artist's own how to strip paint from a car the various figures representative of questions relating to ffrom existence.

In this light, the babe at the far right signifies newborn life. The figure of questionable sex whose back is turned to the viewer and who appears to inspect his or her underarm could be understood as the beginning of an individual's realization of gender. The apple-picking male and the girl to his left who sits eating an apple reenact the fable of Adam and Eve and the quest for knowledge.

The old lady at the far left of the frame sits on what is the formula for sodium bromide verge of death, unclothed as a parallel perhaps to the babe frok the painting's far right. Di Symbolist art is characterized by allegory, timelessness, the whay, and ambiguity. Toggle navigation.

The first modern photograph? Alfred Stieglitz, The . Dec 19,  · “A human being is part of the whole — called by us universe, a part limited in time and space. He experiences himself, his thoughts and feelings as something separate from the rest, a Author: Daniel Christian Wahl.

The question of where we humans come from is one many people ask, and the answer is getting more complicated as new evidence is emerging all the time. For most of recorded history humankind has been placed on a metaphorical, and sometimes literal, pedestal.

Sure, modern humans were flesh and blood like other animals. But they were regarded as being so special that in the Linnaean taxonomy that prevailed well into the second half of the 20th century they were given their own family, the Hominidae. This distinguished them from the Pongidae, the separate family used for the three African great apes — the common chimpanzee, bonobo and gorilla — plus the orangutan from Southeast Asia.

In the 19th century the only evidence available for determining the closeness of the relationship between any two living animals was how similar they were in terms of what the naked eye could tell from their bones, teeth, muscles and organs. The first person to undertake a systematic comparative review of these differences between modern humans and the apes was English biologist Thomas Henry Huxley.

He speculated that because African apes were morphologically closer to modern humans than the apes from Asia, then the ancestors of modern humans were more likely to be found in Africa than elsewhere. Developments in biochemistry and immunology during the first half of the 20th century enabled the search for evidence of the relationships between modern humans and the apes to shift from macroscopic morphology to the morphology of molecules. The results of applying a new generation of analytical methods to proteins were reported by the Austrian-born French biologist Emile Zuckerkandl and American biologist Morris Goodman in the early s.

Zuckerkandl used enzymes to break up the protein component of haemoglobin into its peptide components. He showed that the patterns of the peptides from modern humans, gorilla and chimpanzee were indistinguishable. Goodman used a different method , immunodiffusion, to study albumin, a serum protein. He showed that the patterns produced by the albumins of modern humans and the chimpanzee were identical. He concluded that this was because the albumin molecules were, to all intents and purposes, identical.

Proteins are made up of a string of amino acids and in many instances one amino acid can be substituted for another without changing the function of the protein.

In the late s, the American anthropologist Vince Sarich and New Zealand biologist Allan Wilson exploited these minor differences in protein structure and concluded that modern humans and the African apes were very closely related.

They also provided the first molecular clock estimate of modern human-African ape divergence, dating the split to only around five million years ago. This date was less than half of contemporary estimates based on fossil evidence. The discovery by James Watson and Francis Crick, with unwitting help from Rosalind Franklin, of the basic structure of DNA , and the subsequent discovery by Crick and others of the nature of the genetic code, meant that the relationships among organisms could be pursued at the level of the genome.

Nowadays technological advances mean that whole genomes can be sequenced. Over the past decade researchers have published good draft sequences of the nuclear genomes of the chimpanzee , orangutan , gorilla and the bonobo. More and better data are steadily being accumulated, and in a review of ape DNA based on the genomes of 79 great apes was published. These new ape genome sequences support the results of earlier analyses of both nuclear and mitochondrial DNA that suggested modern humans and chimpanzees are more closely related to each other than either is to the gorilla.

When DNA differences among modern humans and the great apes are calibrated using the best palaeontological evidence for the split between the apes and the old world monkeys, those differences predict that the hypothetical common ancestor of modern humans, chimpanzees and bonobos lived about 8 million years ago.

Most researchers now recognise the modern human as hominins. In part this is because the fossil record for human evolution seems to grow exponentially, with the author of each new discovery often claiming that the textbooks need to be rewritten. The interdisciplinary nature of palaeoanthropology also means that new evidence that helps us make sense of our ancestry does not always come in the form of new fossils.

It comes from advances in a range of disciplines that include archaeology, comparative anatomy, earth sciences, evolutionary biology, genomics and primatology. A further complicating factor is that the human fossil record does not just consist of the fossil evidence of our direct ancestors. Many of the fossils belong to lineages that do not make it to the surface of the Tree of Life. They belong to extinct close relatives, and the task of sorting close relatives from ancestors is one with which we are only just now beginning to grapple.

They represent some of the most interesting chapters in human evolution. Understanding the origins of our own genus Homo means establishing what fossils we recognise as being the first early humans. Sometime before 4 million years ago we see the first evidence of the genus Australopithecus.

These fossils sample the kind of creature that was most likely the ancestor to the genus Homo. Around 2. One of these, Homo habilis , almost certainly made stone tools, had a slightly larger brain than Australopithecus , stood upright and regularly walked on two legs.

Some recognise a second species, Homo rudolfensis , about which we know even less. These possible human ancestors lived alongside close relatives that were almost certainly not our ancestors. These species are called Paranthropus or robust australopiths — they had small brains, big jaw bones, large flat faces, and huge chewing teeth. They lasted for at least a million years, so whatever they were eating which is still a mystery they were successful in the sense that they lasted as long in the fossil record as the average mammal.

But some researchers think that Homo habilis and Homo rudolfensis are not different enough from the australopiths that preceded them to justify being included in the genus Homo. They claim that the size and shape of their body and the size of their teeth and jaws was little different from that of the australopiths.

This means that their locomotion and diet had not shifted far enough in the direction of pre-modern Homo species such as Homo erectus to justify inclusion in Homo. Also, because it is becoming evident that australopiths may have been making tools earlier than Homo habilis it means that tool-making can no longer be seen as the sole prerogative of Homo.

There is a developing consensus that the relaxation of the criteria more than 50 years ago that saw the inclusion of Homo habilis into the genus Homo needs to be reconsidered. Species that emerge slightly later from Africa, such as Homo ergaster , fit much more clearly within what we understand by the genus Homo.

That species probably left Africa around 2 million years ago and migrated ultimately as far east as China and Indonesia where it evolved, eventually, into Homo erectus. A number of further migrations out of Africa probably occurred after the initial Homo ergaster migration, one of which, Homo heidelbergensis , is considered by many palaeoanthropologists to be the ancestor of both Neanderthals Homo neanderthalensis and modern humans Homo sapiens.

As far as we know, Neanderthals evolved outside of Africa, perhaps in response to the ice ages of Europe. Our ancestors remained in Africa where perhaps as early as , years ago, as revealed from recent redating of the Moroccan site of Jebel Irhoud, were well along in the process of evolving into modern humans.

Once we get to the origins of our own species Homo sapiens we have the added advantage that we are able to now use next generation sequencing methods to recover ancient DNA aDNA. As geneticists recover ancient genomes from different extinct hominin species, they are generating insights that are not possible from comparing the anatomy of the fossils alone. There is now fossil evidence from teeth to suggest that Homo sapiens may have been in China by , years ago and in South East Asia by 67, years.

The discovery of some distinctive modern human DNA within the DNA recovered from a Neanderthal fossil suggests that modest interbreeding was occurring between Neanderthals and modern humans in Central Asia by , years ago. Modern humans have not shared the planet with another hominin species for several tens of thousands of years.

But before that, in the past , years or so, there is fossil and DNA evidence of several hominin species, including the recently reported archaic hominin Homo naledi. First and foremost there was Homo neanderthalensis , whose range overlapped with modern humans in the Near East. Neanderthals most likely became extinct as a result of direct competition with the more technologically sophisticated Homo sapiens. The evidence from DNA shows that there was interbreeding between our species and pre-modern humans, including the Neanderthals and the other enigmatic hominin referred to as the Denisovans.

We do not yet know how and when Homo erectus became extinct. It would appear that another unexpected side experiment in hominin evolution, known from the island of Flores and called Homo floresiensis most likely became extinct sometime after 60, years ago. Indeed this hominin may represent something far more significant than simply an interesting side experiment, with many leading palaeoanthropologists arguing that the Hobbit may represent a pre-ergaster migration out of Africa. Even though thousands of hominin fossils have now been recovered and described there is still much work to be done.

Was there a hominin that successfully migrated out of Africa prior to Homo ergaster? Did most of human evolution occur in Africa? Did some important transitions occur outside of Africa?

When did Homo erectus become extinct, and was there genetic exchange between erectus, sapiens and perhaps other hominin species? As is often the case in science, with the recovery of additional data, in this case fossils and DNA extracted from fossils, we generate more questions than answers.

But ultimately all of this new evidence will result in a far more sophisticated appreciation of not only our evolution, but also the evolution of our extinct fossil cousins.
