On the southern coast of Peru lies the desert peninsula of Paracas. This barren landscape is where Peruvian archaeologist Julio Tello made an astounding discovery in 1928. His efforts uncovered a massive and complex graveyard buried under the sand and rocks. In these tombs Tello found some of the most controversial human(?) remains in history. The bodies had the largest elongated skulls in the world and have since been called the Paracas skulls. Tello found a total of more than 300 skulls and they have been dated at around 3,000 years old. A recent DNA analysis performed on some of those skulls has presented amazing results that could challenge the current perspective of the human evolutionary tree. Several other cultures have practiced skull elongation or deformation but the techniques they used produced different results. Certain South American tribes used to bind infants’ skulls in order to change their shape. Binding the head between pieces of wood modified the appearance of skulls by applying constant pressure over a long period of time. This type of cranial deformation changed the shape but it did not alter the size, weight or cranial volume; these are all standard characteristics of a regular human skull. The Paracas skulls are different. Their craniums are 25% larger and 60% heavier than regular human skulls which led researchers to believe they couldn’t have been modified through binding. They are also structurally different and only have one parietal plate as opposed to the two normally found in human skulls. These differences have deepened the decade-old mystery around the Paracas skulls and researchers haven’t been able to explain their origins. The director of the Paracas History Museum has sent samples from 5 skulls to undergo genetic testing. The samples consisted of hair, skin, teeth and fragments of skull bones. The genetic laboratory was not informed about the samples’ origins in order to avoid biased or influenced results. The results were fascinating. The mitochondrial DNA (inherited from the mother) presented mutations unknown to any man, primate or any other animal. The mutations suggested we are dealing with a completely new human-like being, very distant from Homo sapiens, Neanderthals or Denisovans. The Paracas individuals were so biologically different from humans they wouldn’t have been able to interbreed. “I am not sure it will even fit into the known evolutionary tree”, one geneticist added. The implications of this discovery are huge. Who were the mysterious Paracas people? Did they evolve here on Earth on a path so different from us that they ended up looking drastically different? If not, where did they come from? Are any of them left? This breakthrough brings up more questions than it answers but counts as another piece of evidence suggesting that we are not alone.

Thanks to all. If we really moving toward global warming due to Green house gases than we can easily control it. I've a project but I wanna present it in any Confrence.

I'm much confussed when I look at the temprature of different regions and other climate factors because some time it seems that we are moving global warming and some time it seems like global cooling. what you think?

well thankx bro but I wanna conduct some expariment about this if you have any idea plz tell me.

Try to understand me I think it is not possible that in a rotationg media the mass of gas accumulate in the the center....

According to the nebular hypothesis, stars form in massive and dense clouds of molecular hydrogen—giant molecular clouds (GMC). They are gravitationally unstable, and matter coalesces to smaller denser clumps within, which then proceed to collapse and form stars. Star formation is a complex process, which always produces a gaseous protoplanetary disk around the young star. This may give birth to planets in certain circumstances, which are not well known. Thus the formation of planetary systems is thought to be a natural result of star formation. A sun-like star usually takes around 100 million years to form. The protoplanetary disk is an accretion disk which proceeds to feed the central star. Initially very hot, the disk later cools in what is known as the T tauri star stage; here, formation of small dust grains made of rocks and ices is possible. The grains may eventually coagulate into kilometer-sized planetesimals. If the disk is massive enough the runaway accretions begin, resulting in the rapid—100,000 to 300,000 years—formation of Moon- to Mars-sized planetary embryos. Near the star, the planetary embryos go through a stage of violent mergers, producing a few terrestrial planets. The last stage takes around 100 million to a billion years(wikipedia). Plz concentrate on this sentence how it is possible that in a rotating medai the objevt which have very low desity accumulate in the center of media as you all well known sun have very low density as compare to its planets.....

Dera plz note the statement of hypothesis and aslso about the densties of planets and our star(Sun).

I have a big confussion about this hypothesis some time I think thak we should make some amendments in this hypothesis....
