Native Americans would still own the lands that got stolen from them and wouldn't have been murdered  and killed by disease

Man_with_a_Plan has no proof that there is no proof. His statement that no theories are sound or have proof is just his opinion and purely speculatory. There is no proof.\n\nI, on the other hand, like the "Murder on the Orient Express Theory". I think that there was huge changes in ocean circulation due to the continents coming together WELL BEFORE Pangaea formed. The geologic evidence suggests that the extinction happened in different places around the world at different times, which suggests that no single event is responsible. I believe that cooling events like plume volcanism in the Siberian traps coupled with warming events like methane hydrate release and greenhouse effect along with the continental positioning at the time may have worked together to cause extreme changes in ocean circulation at various parts of the world at different times, attributing to the extinction event.\n\nVariations in temperature due to greenhouse warming and on/off sulphide cooling would have had the greatest immediate impact on planktic (ocean surface) and shallow water organisms. I also think that ocean circulation was also greatly affected not only by the temperature variations but also the circumstantial orientation of the continents. Heat transport to the north would have been innefficient and consequently northern regions would have been subject to extreme cooling, even at relatively low latitudes. In the southern regions there would have been a huge temperature gradient between top and bottom waters. If this was enough to stop deep water formation and ocean turnover, benthic (bottom dwelling) species would have been destroyed by the lack of oxygen and intermediate to surface water species would have suffered from a lack of nutrients. Because most of the Earth's life at the time was in the water, I am quite sure that it was likely some change in ocean circulation that dealt the fatal blows to life. Obviously good carbon isotope data from the period would be needed to verify this hypothesis. \n\nLife on land would have suffered greatly by climate changes induced by changes in ocean circulation, as well as the extreme variations in temperature. Tropical species would have been devastated by cooling events caused by the plume volcanism.\n\nThere is lots of proof for everything; there just is no definite information that can, as of yet, say for sure exactly how it all happened. That's a tough thing to do, but I really dislike people who refute the claims of others without presenting any evidence themselves.

They didnt exist so the answer is no because they needed to exist first in order for the analysis to begin.\n\nWe know they didnt exist because science has demonstrated that we evolved to "humans" we were simply plopped on earth. We know the earth is billions of years old. We have found the remains of hominid life forms and we have shown the process of evolution. \n\nDividing this into macro and micro is silly and the uptiome of rationlization. Sorry, I too wish I was made in God's image.

The only logical explanation is that people other than the Europeans had already discovered the lands and fed the information upon which the de Virga world map was based.\n\nThere is a book, titled 1421, authored by Gavin Menzies. He argues for the proposition that the Chinese had been exploring the world -- and had discovered North America -- long before the Europeans did. His website is: www.1421.tv.

for the same reason as llamas pandas and koalas aren't mentioned. The peoples of the Eastern end of the Mediterranean probably travelled no more than a hundred miles from their place of birth in their lifetime and so had no concept of other continents and other flora and fauna, let alone extinct species

Not really, especially on that scale, because at the time that most of the world was "discovered," Europe was really the only area that had decent seafaring technology.\n\nHowever, there were probably discoverers on a more local scale.

While it might be possible that some of these creatures exist, it certainly can't be said to be 'probable'.\n\nWe are still finding new species of mammals and birds all the time.  Genetic studies have even shown us that some of the critters we thought we knew are more diverse than we thought.\n\nRecently it was discovered that the species we know as the African elephant is in fact two species, a savannah species and a forest species.  So we have 'found' one of the largest species of land mammal just in the last few years.  Another study found that there was a population of the Bactrian camel (the one with two humps) that was actually a separate species too.\n\nSo it is possible that there may be some critter hidden off in the deep forest somewhere that we've never seen before.  But the chances of something like Bigfoot/Sasquatch remaining undiscovered in the rather well explored forests of North America are rather low.\n\nThe best chance for new, exciting and incredible discoveries are in the seas.  We really have barely scratched the surface in our exploration there, and there could be all kinds of new, even huge and exciting finds down there.\n\nJust in the last few years, the Megasquid was described, whose body is larger than that of the Giant Squid (although the tentacles aren't as long), actual live footage of the Giant Squid was finally taken, and Coelacanths were found off the coast of Indonesia, 10 000 km from where it was thought was the only place they existed.

Everest wasn't discovered, it's always been there.  Western civilization has known about the Himilayas and Asia since the times of the Romans and probably before that.

A number of theories exist regarding the naming of North and South America. The most widely recognized is that they are named after Amerigo Vespucci, who was the first European to suggest that the Americas were not the East Indies, but a New World, previously undiscovered by Europeans. The second and less generally accepted is that the continents are named after an English merchant named Richard Amerike from Bristol, who is believed to have financed John Cabot's voyage of discovery from England to Newfoundland in 1497. A third theory that has been advanced is that America was named for a Spanish sailor bearing the ancient Visigothic name of 'Amairick'.\n\nThe America's are the European name for the area know as the new world, once humans formd a country the people who are citizens are called AMERICAN's, a shortened name of USA. All US citizens are called Ameicans but not all people who live in the US are called that, some are called Illegal Immigrants, Undocumanted workers or plainly immigants

America was not "discovered" since it already inhabitants.

It is probably still somewhere in the middle of the Atlantic Ocean.\nIt has never been recovered because it has never been found.\nI personally have never seen it but I do not know if someone\nhas seen Atlantis or not.

no.  you're going to get a variety of responses ranging from the reasonable, like david's to the utterly ridiculous, like a lot of the others already here.\n\nas for the claims that the crater in the yucatan is supposition or "only a theory" (ever heard these words before?) there is a lot of evidence for it:\n\n"Probably the most convincing evidence for a worldwide catastrophe was the discovery of the crater which has since been named Chicxulub Crater. This so-called smoking gun is centered on the Yucatan Peninsula of Mexico and was discovered by Tony Camargo and Glen Pentfield while working as geophysicists for the Mexican oil company PEMEX. What they reported as a circular feature later turned out to be a crater estimated to be 180 kilometers in diameter. Other researchers would later find that the end-Cretaceous extinction event that wiped out the dinosaurs had lasted for thousands of years instead of millions of years as had previously been thought. This would be the final piece of evidence that convinced the vast majority of scientists that this extinction resulted from a point event that is most probably an extra-terrestrial impact and not from increased volcanism and climate change (which would spread its main effect over a much longer time period)."\n\nIt seems to be a bit more than a layer of clay in the ground.\n\nwhether this is worthy enough for biblical mention is debatable, but it seems that such a large impact would have had tremendous effects on any living species at the time, including (as creationists claim) humans.  why is there no mention of it either in the bible or other human cultures?  probably because it happened long before any humans were around.  it would have been a very important event, more important than a lot of the mentioned events in the bible.\n\nand if it is mentioned in the bible, please provide a passage.

Many of the largest forests are undiscovered. Scientists are discovering new species of plants, animals, and insects all the time. It's only a matter of time before a new disease is discovered that humans have not come upon in the forests yet.\n\nDeep areas of the oceans have yet to be discovered, too. In both cases the surface area so large it will still take years and years to compile enough data to know what is where.

For the last 15 million years or so, Antarctica has been mostly ice covered.  But underneath, the ancient rocks that make up this continent are still there.\n\nBefore that, it was still connected to Australia and India and was located farther to the north on the globe.\n\nFar enough back (about 160+ million years) and it was located on the equator.\n\nAbout 25 million years ago it split off from the other continental bits and once the Antarctic circumpolar current developed, the weather isolation and cold kicked in, creating a very cold desert with little precipitation, but no meltingof the snows.\n\nOver the subsequent millions of years an average ice pack depth of 2 miles developed.\n\nif it all melted, the oceans would all raise something like 200 feet!

I figure the only places left are some of the more inaccesable dense rainforests of the South American continent. But the other possibility would be underground, cavers or speliologists have been trying to probe the depths of the earth by exploring underground caves and tunnels as well as flooded waterwaters to see how far they can go below the earth. That besides the oceans must be the last place where humans have never ever set foot on in this earth.

To see a future map of the globe for +250 million years go here:\nhttp://www.scotese.com/future2.htm\n\nYou will see the "Pangea Ultima" with North and South America up against Africa, and Africa against Eurasia. Australia and Antarctica are joined again. The present day Indian Ocean may be a landlocked sea.\n\nIn one billion years it is likely that the process of combining and separation of plates will have completed itself several times. There is no realistic way of projecting the plate motion this far in the future, since the rate of motion may change over time as the earth's heating from internal sources of radioactive decay gradually decreases.\n\nHere are some decay series in case you want to see what rate of decay will eventually begin effecting the planet's tectonics.\nhttp://hyperphysics.phy-astr.gsu.edu/hbase/nuclear/radser.html
