What caused the mammoth to go extinct and when did this occur?
603296
During the ice age, mammoths were hunted by both neanderthals and modern humans for their meat, fur, and tusks. This helped cause extinction of the woolly mammoths. Further more, after the last ice age, the mammoths couldn't cope up with the new environment, because they had too much fur.

Not sure whether I am on your wavelength, but ... if you are referring to the fabled Golden Age of earth it's the time that modern-day archaeologists try to ignore because it just doesn't fit with their text books. On the celtic shelf (prehistoric Britain) the ice-age was at its maximum around 20,000 BC, and then it began to slowly melt. Over the next 5000 years ice receded and the sea levels rose and Britain (still attached to continent) began to take shape. By 15,000 BC it was totally ice-free. The people of modern-day Northern France had followed the ice northwards and quickly populated this new land, and the flora and fauna flourished. The period that followed is the 4000 years that historians like to leave out of lectures and TV archaeologists conveniently ignore. Imagine 4000 years of temperate weather in a green verdant land, easily defendable therefore generally peaceful, a time of plenty. This period is equal to the time period from raising the stones at Stonehenge to the present day. In my opinion this is the Golden Age, however it didn't last, around 11,000 BC the snow and ice moved back in and the northern half of Britain and Ireland was once again frozen and glaciated - this chilly situation lasted for around 1500 years and is known as the Younger Dryas period (which ended abruptly in 9600 BC and that's another subject that I could go on for hours about), but I hope that helps with your question about the Golden Age.

The prevailing theory at this time is an asteroid impact that caused a nuclear winter. more than half the life on earth is thought to have become extinct at this time. I believe it was at the beginning of the cenazoic era. as evidence there is a layer of iridium at this geologic layer that covers the entire planet. Otherwise iridium is pretty rare on earth but quite common in asteroids.\n\nWhile this event may have contributed to the onset of an iceage, the energies involved were probably not great enough to give credit for an iceage.

One of the clearest sign of a massive impact was massive extinction of life. The greatest extinction event sometimes called the Great Dying was the Permian-Triassic extinction. It occurred approximately 251 million years ago (mya), forming the boundary between the Permian and Triassic geologic periods. It was the Earth's most severe extinction event, with about 96 percent of all marine species and 70 percent of terrestrial vertebrate species becoming extinct. Recently, a 300-mile-wide crater was discovered in the Wilkes Land region of East Antarctica, which is believed to be linked with the extinction.\n\nA 300-mile-wide crater more than a mile beneath the East Antarctic Ice Sheet was found using gravity fluctuations measured by NASA's GRACE satellites to peer beneath Antarctica's icy surface, imaging a 200-mile-wide plug of mantle material—a mass concentration, or "mascon" in geological parlance—that occurs within the Earth's crust and appears to have been emplaced somewhere between 100 and 500 million years ago—a broad time span that brackets the specific age of the Permian-Triassic extinction.\n\nWhen the scientists overlaid their gravity image with airborne radar images of the ground beneath the ice, they found the mascon perfectly centered inside a circular ridge some 500 km (300 miles) wide. The Wilkes Land crater is more than twice the size of the Chicxulub crater in the Yucatan peninsula, which marks the impact that may have ultimately killed the dinosaurs 65 million years ago. The Chicxulub impactor (most likely an asteroid) is thought to have been 6 miles wide, while the Wilkes Land impactor (either an asteroid or perhaps a large comet nucleus) could have been up to 30 miles wide—four or five times as wide.

The next ice age is not going to happen for a very long time, there was only one a few million years ago. What could make it happen is a nuclear war or asteroid collision with the earth.

The Tunguska Event.\n\nA huge non-nuclear, sub atomic explosion in the skis over Siberia. \n\nThe theories around the cause of the explosion are varied;\n\nStray Anti-Matter particle.\nComet/ Meteor overheating and exploding on entry.\nSolar Particle disruption caused by mass sunspot activity.\nBy product of a Solar Mass Ejection event. \nA Primordial Black hole.\n\nOne theory I read stated that according to the "math" the instantaneous opening and collapse of a wormhole would release the same amount of energy.\n\nAny way, it happened in 1906, but a "rescue" mission wasn't sent for 10 years because at the time that part of Siberia was so remote they had to build railways roads and bridges to get there.

You have 5 major extincion events in Earth's history:\n\nThe more famous is the K-T Extinction Event aka the day the dinosaurs became oil about 65 million years ago.  That killed the majority of the animals on land, sea and air.  \n\nThe most powerful was the one that occurred 251 million years ago and took 95% of all life on Earth.

Dang, are you the one who made the dinosaurse go extinct... Note... I think we found the culprit...

there are some efforts going on to bring mammoth to life by using its frozen sperm. with an african elephant. as far as cloning goes i dont have any idea.

As a late development of the dinosaurs Archeopteryx would have come extinct at the Cretaceous-tertiary boundary about\n66 million years ago (when all dinasaurs became extinct)the cause was a large asteroid that hit he earth off Yucatan in Mexico causing cataclysmic environmental changes.\n\nhttp://en.wikipedia.org/wiki/Archaeopteryx

From having studied volcanicity when I was at university, the only one that springs to mind would be Vesuvius, which erupted in Italy in 79AD. Obviously during this time, populations where not as they are today, but 95% of all human were not wiped out during this eruption. However, all but one in the towns of Herculaneum and Pompeii died during the pyroclastic flow following the eruption. Just out of interest the guy that survived was in jail! How said crime doesnt pay ;-)\n\nUnfortunatly 10,000years ago there was no-one to document the evidence as such, only what we can deduce from the rocks from that time. \n\nHowever, if you remove the 10,000year bit of your question and the human element, there is a possible anwser back 60 to 65Ma. The Deccan Traps in India was a flood basalt which was so huge that it is one of the potential reaons the Dionsaurs died out. The volume lava produced during the eruption (the eruption was not one but many over a period of time) was something in teh region of 1 to 2 million square kilometers. It is widely recognised that the climatic effect of such a supervolcano would lead to a nuclear winter. \n\nHope this helps!

the atmosphere was heavily clouded with dust that took a very long time to settle out. This caused a drastic cooling of the surface temperature of the earth. Dinosaurs, being cold blooded, could not survive that drastic a climatologic change. In fact, it is posited that an ice age began as a result of the impact and dust. If you look at major volcanic eruptions over the past few hundred years you can see the same phenomenon occurring with regard to temperatures.

Cloning has become a widely debated issue in the media since 1996, when a group of Scottish scientists led by Ian Wilmut cloned Dolly, a sheep that was the first clone of an adult mammal. The cloning process involves destroying the nucleus of an egg cell of the animal that will carry the clone and injecting a donor nucleus from the individual to be cloned into that egg cell. The resulting egg thus has a nucleus from the donor animal (which may be an endangered animal) and can develop into an animal that has the same genetic makeup as the donor, thus making the resulting offspring a clone.\n\nSince Dolly's appearance, a wide variety of uses for mammalian cloning have been proposed, including using cloned animals to produce superior livestock and to simplify the process of creating transgenic animals (genetically modified animals that can make human proteins in their milk, for example). Several groups have suggested cloning endangered or recently extinct species. A company called Advanced Cell Technology used a cow named Bessie to clone an Asian gaur, an endangered oxlike animal native to India and Burma (the cloned gaur died of an ordinary disease two days after his birth). Scientists also hope to move on to cloning extinct animals, perhaps starting with the cloning of the now-extinct bucardo mountain goat from Spain; scientists froze some tissue from the last living animal before the species became extinct.\n\nCloning endangered and extinct species has raised heated debate in the scientific community and beyond. On the one hand, many say it may offer us an opportunity to protect animals such as the giant panda from extinction so that our descendants will be able to see the beauty of these creatures. Some claim that cloning may help us bring back recently extinct species. Still others just want to have an opportunity to see a mammoth. (By the way, cloning mammoths from tissues frozen in Siberian permafrost is considered impossible with the current techniques because their DNA has become fragmented. In addition, scientists do not think that fossilized species such as dinosaurs can be cloned.) Indeed, if successful cloning of an endangered or recently extinct species is possible, we may be able to boost the populations of these animals.\n\nOn the other hand, cloned populations consist of genetically identical individuals, leading to high susceptibility to many diseases and slow adaptation to the environment. In addition, some argue that introducing extinct species back into the wild may upset the natural balance and have disastrous effects on the populations of other species. Such concerns are probably not as relevant with recently extinct species, where their extinction has usually been caused by human interventions, such as destruction of habitats and hunting. We do have to consider such issues when we start talking about bringing back mammoths, but the cloning of long-extinct species is still only a theoretical possibility. Concerns remain, however, that endangered and recently extinct species could be brought back to a world where their habitats no longer exist, and they will only be able to survive in zoos.\n\nAnother concern voiced by animal conservationists is that cloning endangered species would be viewed by the public (and governments) as an alternative to the breeding and habitat-protection programs already in place. Such possibilities are especially alarming as cloning techniques become cheaper and may be viewed as a less costly alternative to the more traditional means of protecting endangered species. Of course, cloning cannot serve as a substitute for such programs, because cloned animals lack the genetic diversity that is crucial to survival, and they still need habitats to live in.\n\nAs you can see, cloning is far from being able to serve as a Noah's Ark that would save all endangered species from extinction, but together with habitat protection and breeding programs, it may help some endangered and rece

The extinct critter generally known as the woolly rhino (Coelodonta antiquitatis) was once quite common throughout Europe and Asia between about 400,000 years ago and 10,000 years ago.\n\nIt is known through numerous fossil specimens, as well as preserved and frozen specimens in ice, and beautifully rendered cave painting at places like Chapelle aux Saints.\n\nThey have been found from Spain to South Korea, and seem to have been particularily abundant in what is now Russia.\n\nAlthough they seem to have lived in very similar habitats as the woolly mammoth (Mammuthus primigenius), they do not appear to have crossed into the Bergingia region and into North America as the mammoths did.
