Evolution? How?

Where do you think flu vacine comes from? How do you think they develop flu vacine without understanding evolution?

Don't pretend that flu viruses 'evolve', CI. They are still viruses.

That successive generations are different from one another is no more remarkable than you being different from your parents.

And that viruses can resistant chemical attacks on them is no more remarkable than your body's ability to do so. Are you 'evolving' when your body responds to a threat to keep you alive and well? (You probably think so but you aren't.)

Unintelligent Design
A monstrous discovery suggests that viruses, long regarded as lowly evolutionary latecomers, may have been the precursors of all life on Earth

AFRICA'S NEW OCEAN

A Continent Splits Apart

By Axel Bojanowski

Normally new rivers, seas and mountains are born in slow motion. The Afar Triangle near the Horn of Africa is another story. A new ocean is forming there with staggering speed -- at least by geological standards. Africa will eventually lose its horn.......

AVERAGE tectonic motion is usually computed based upon how fast and far ophiolitic magma erupts at seafloor spreading centers and then its routinely timed by the distance travelled normal to the ocean vent before each magnetic reversal imprints its "Bar Code" on the suboceanic lava. Seeing the process begin does, in no way mean that the scientists are stating that such initial opening events will persist. When a plate begins to spread at a center, theres no resistance and the plate masses are small. Soon (geologically) the speed will reduce to about 2 to 4 cm /yr. India has been a rapidly moving continental mass with some episodes of spreading at about 10 cm per year or thereabouts.

The process is wonderful and gives us a planetary "speedometer". If you look at teh Atlantic and Pacific spreading centers to their trailing or subducting ends, we see that there are no sediment or magmatic layers older than Jurassic , which is a pretty good way to do a Time, rate, and distance problem.

Popular science mags would lose readers if theyd print all the qualifiers and boring data . Anyway, if you look at a map of the horn of Africa this is one of a few rare zones on earth that are called "triple junctions" Three plate margins come together here at the junction of the red sea, gulf of Aden, as well as the East Africa Rift valley. There was a "plume" beneath this area , a plume of volcanics thats active since about 30 my ago. After the initial vulcanism Aden and the Red sea began to open and the unusual thing is that the Red sea is actually crust being "strtched" rather than new oceanic ophiolitic crust being formed. The East Africa rift valley has always been called an "aulocogen" sort of a failed rift since no new ocean basin had been opening within it for the 30 my. Now that it seems to be beginning I inclined to remind the authors that triple point stresses need to be resolved over the entire life of the tectonic feature, not because some "popular Science" dude wants to jazz up a story with a speedy sea floor spread.
Its about goddam time sez I. I was sick of Africa with this damn quiet plume. Plumes, which are a slightly different tectonic model base, are always quick to open , and then slow down, and in that fashion theyre slightly different from mid ocean ridges. Plumes are what we call " mantle source hotspots", like under Hawaii, or the Deccan plateau or the Parana basin , or the Snake River Plain. At a hotspot we often have the hotspot and the overlying plate moving separately. Torsvik and Van der Voo (2002) used geomag data to plot the differential movement of the Hawaian Island hotspot at about 3 cm a year moving SW and the overlying ocean crust moving NW at a speed of 4 cm a year. They solve the motion using vector analyses and inelastic collision physics (at very low velocities obviously).

I hope youre not implying by your "interesting " statement that this , in anyway concurs with someones young earth beliefs, cuz it doesnt.

Yeh Iget most of the AGU stuff. Good stuff Pauligirl I was more into a non technical explanation of the explanation of a popular science article posted by RL. Im certain that where he was going was to propose that, because some resaerchers have found an explosive movement over the Afar triple point ,(in his mind) this confirms that continental drift is occuring at much faster rates than the avg 2-4 cm/yr rates from mid oceanic ridges and 2 -10 cm/yr for triple points.If continental drift is faster it could mean that the earth is younger than standard geochron has computed
I was trying to avoid sounding like the Goddard boys since this is not a symposium on "hotspot plumes" but a thread where our friend has come fully loaded with agendas. I enjoy putting the technical into words that non geologists would get some understanding. I hope I succeeded.

Torsvik and Vander Voo, IMHO , still have the best on this trip point and plume dynamics. It was in Earth and Planetary . Sci. Lett. v202 (2002). This is an open source journal. When I get to my office Ill see if I cant find the open source lists of free scientific journals. Theres a boatload and they dont charge except for service sponsors and software and lab and field equipt.The readers arent thei main sorces of revenue. The internet has changed the dynamics of dissemination in a lot of cases. However journals like GSA still persist in makin us pay through the nose. Even fellows dont get any breaks.

I seem to find a lot more truth from the Bible and not what a bunch of scientists tell me. come on seriously how believable is all the "scientific" stuff they say is right. a monkey turning in to a man? A big bang and the world was formed? How did the stuff that collided get formed?

I hope youre not implying by your "interesting " statement that this , in anyway concurs with someones young earth beliefs, cuz it doesnt.
