    The Earth May Get A New Ocean!

    Giant Crack in Africa Will Create a New Ocean

    A 35-mile rift in the desert of Ethiopia will likely become a new ocean eventually, researchers now confirm.


    The crack, 20 feet wide in spots, opened in 2005 and some geologists believed then that it would spawn a new ocean. But that view was controversial, and the rift had not been well studied.


    A new study involving an international team of scientists and reported in the journal Geophysical Research Letters finds the processes creating the rift are nearly identical to what goes on at the bottom of oceans, further indication a sea is in the region's future.


    The same rift activity is slowly parting the Red Sea, too.


    Using newly gathered seismic data from 2005, researchers reconstructed the event to show the rift tore open along its entire 35-mile length in just days. Dabbahu, a volcano at the northern end of the rift, erupted first, then magma pushed up through the middle of the rift area and began "unzipping" the rift in both directions, the researchers explained in a statement today.


    "We know that seafloor ridges are created by a similar intrusion of magma into a rift, but we never knew that a huge length of the ridge could break open at once like this," said Cindy Ebinger, professor of earth and environmental sciences at the University of Rochester and co-author of the study.


    The result shows that highly active volcanic boundaries along the edges of tectonic ocean plates may suddenly break apart in large sections, instead of in bits, as the leading theory held. And such sudden large-scale events on land pose a much more serious hazard to populations living near the rift than would several smaller events, Ebinger said.


    "The whole point of this study is to learn whether what is happening in Ethiopia is like what is happening at the bottom of the ocean where it's almost impossible for us to go," says Ebinger. "We knew that if we could establish that, then Ethiopia would essentially be a unique and superb ocean-ridge laboratory for us. Because of the unprecedented cross-border collaboration behind this research, we now know that the answer is yes, it is analogous."


    The African and Arabian plates meet in the remote Afar desert of Northern Ethiopia and have been spreading apart in a rifting process - at a speed of less than 1 inch per year - for the past 30 million years. This rifting formed the 186-mile Afar depression and the Red Sea. The thinking is that the Red Sea will eventually pour into the new sea in a million years or so. The new ocean would connect to the Red Sea and the Gulf of Aden, an arm of the Arabian Sea between Yemen on the Arabian Peninsula and Somalia in eastern Africa

    Someone posted this link on another board, that I sometimes visit.

    At the end of the Permian was Greatest Extinction of All Time



    Vast deserts covered western Pangea during the Permian as reptiles spread across the face of the supercontinent. 99% of all life perished during the extinction event that marked the end of the Paleozoic Era.

    This is the way the World may look like 50 million years from now!

    "Pangea Ultima" will form 250 million years in the Future

    The next Pangea, "Pangea Ultima" will form as a result of the subduction of the ocean floor of the North and South Atlantic beneath eastern North America and South America. This supercontinent will have a small ocean basin trapped at its center.

    It seems that we should get rid of the African immigration problem towards Europe within the next 50 mio. years or they will be able to come to us by the overland route.

    (Damn Africa, not only the people want to immigrate, no, the whole continent itself immigrates and shoves our Europe further North! )

    On a more serious note, 50 mio. years is such a long time, I doubt that there will be any human beings like us in the future. Either we evolved further or we ceased to exist.

    I'd be interested in seeing what new creatures form within 50 millions years.

    I doubt that shifts in the Earth's crust would be sufficient enough to greatly destroy any life, as shifting of the Earth's crust, would be gradual and slow, I would think. Other factors, caused as result of the shift, such as isolated Earthquakes, changes in weather, tidal waves, & volcanoes, might be enough to kill isolated populations. If there was ever a mass extinction, I would think that insect life might have the best chances for re-population. I would doubt that there would be very many changes to aquatic life, as it has remained pretty much, the same today, as it was when the dinosaurs were living.

    SAN FRANCISCO, March 9 (Reuters) - It takes the Earth about 10 million
    years to recover from the mass extinction of plant or animal species -
    - far longer than previously thought, two scientists reported on
    Thursday.

    And it takes the environment just as long to recover from the
    extinction of even a few species, small events which nevertheless rip
    holes in the biosphere that are impossible ever to fully repair.

    "When you lose a species, that exact species is never coming back. You
    can't recreate an animal .... extinction is final that way,"
    paleontologist Anne Weil, a research associate in the Department of
    Biological Anthropology and Anatomy at Duke University, said .

    Insects provide a powerful testing ground for any theory of evolution because their tough external structures have been frequently preserved in exquisite detail in the fossil record. Most textbook arguments for evolution rely heavily on vertebrate bones but vertebrate bone fossils lack the soft tissues that contain the most important information on differences between kinds. Fragmentary fossils always provide fertile ground for evolutionary speculation, but the often-flawless detail of the insect fossils has brought all such speculation to virtual silence.

    Darwinists rarely discuss insects as evidence of evolution, in spite of the fact that the Arthropoda (insects, crustaceans, myriapods and arachnids) must have been a major feature of the evolutionary landscape. Something like 80% of all animal species are insects, and the grand total of all insect species is currently estimated at over 5 million. 1,2 The leading contemporary reference on insects,

    a 770-page tome by professor R.F. Chapman, 3 never even mentions insect origins, and the opus magnum of the late evolutionary champion Professor Stephen Jay Gould avoids mentioning insects altogether. 4

    Insects are not just bothersome pests—they carry out so many critical tasks that ‘Civilization could not survive without them’. 5 Two of these many tasks are the pollination of most of our food crops, and recycling of organic material.

    Consider. We now know that insects arose in fresh water along with vascular plants during the late Silurian about 430 million years ago, and that their closest relatives were freshwater crustaceans similar to the brine and fairy shrimp which survive today.

    Fairy shrimp have an interesting feature — about 7 to 15 pairs of legs lining their long thoraces, one pair of appendages per thoracic segment. By comparison, insects have "only" six legs (3 pairs of thoracic segment appendages). But insects evolved for scores of millions of years between the Silurian and the Carboniferous, when gigantic dragonflies buzzed the horsetails and club mosses. A recount of all those insect appendages modified to other uses lists 3 pairs of legs and two pairs of wings per thorax, with possibly a couple of palps migrating forward to the mouthparts in the head. These suggest a proto-insect crustacean ancestor with a six or seven segmented thorax, well within the body type of freshwater Anostracans.

    Primitive insect-like creatures called springtails were among the earliest known animals to colonize the land, early in the Devonian period almost 400 million years ago. In contrast, fossils of the earliest known true insects are known from later on in the Devonian period. However, reinterpretation of a fragmentary insect fossil from the important early Devonian Rhynie cherts of Scotland shows that the enigmatic Rhyniognatha hirsti was not only a true insect, but relatively derived — that is it had been around long enough to have accumulated some uniquely insect-like features. Although only the mandibles are preserved, it is possible that they once belonged to a winged insect. In any case, the fossil shows that the origin of insects was much earlier than previously thought.

    A common theme in evolution is that large animals descend from much smaller ancestors--and nowhere is this more true than in the case of multi-ton sperm and gray whales, whose ultimate forebears were small, dog-sized mammals that prowled the riverbeds of Asia 50 million years ago. Even more intriguingly, whales are a case study in the gradual evolution of mammals from fully terrestrial to fully aquatic lifestyles, with corresponding adaptations (elongated bodies, webbed feet, etc.) at various key intervals along the way.

    Pangaea started to break up into two smaller supercontinents, called Laurasia and Gondwanaland, during the Jurassic period. By the end of the Cretaceous period, the continents were separating into land masses that look like our modern-day continents.

    I don't really understand what you're post is saying. It seems irrelevent to what I said, and even begins to look far deeper into my simple statement and boast assumptions about my belief.

    Regardless of any extinction you're referring to, genetic shifts will occur and species of the future will present isolated genepools not found in our modern day.

    Even still, of course you assume the factors of that come along with continental shift to be the cause of any environmental/organic change.

    Hell, your argument is automatically flawed in that less than 20,000 years ago there were living creatures that would be foreign to our experience.

    But yes, insects do serve a grand purpose that, according to you, have been ignored by evolutionary scientists. My biology courses and personal readings have never failed to make any mention of their importance, though.

    Well, I hope that this answers more of our questions, but whose to say one way or the other, as it's all theory.

    Inside insects, life is unchanged for 50 million years

    By Birgit Reinert

    July 5, 2002

    For millions of years, life has hardly changed for bacteria that live inside aphids. The genomes of two Buchnera aphidicola bacteria are so similar that no evolutionary time seems to have passed since the species diverged from a common ancestor more than fifty million years ago. The genomes are the same size and have nearly identical architecture: No genes have been moved around, duplicated or acquired—and only a few lost—since the species separated, according to a new study.

    I suppose there's something in it for everyone. We "dwellers of the Alps and the immediate foothills" will be so far north that we get snow again by design, desipite global warming. The Scandinavians need not worry about the Sami since they've almost been shifted across the pole. And the Italians and other swarthy Mediterraneans can finally pride themselves on being geographically "Northern folK", something they deeply wish from their inferiority complex already.

    -Die alte Seele trauernd und verlassen / Verblassend in einer erklärbaren Welt / Schwebend in einem Dunst der Wehmut / Ein Schrei der nur unmerklich gellt-
    -Auch ich verspüre Demut / Vor dem alten Geiste der Ahnen / Wird es mir vergönnt sein / Gen Walhalla aufzufahren?-
