Study Explains Evolution's Molecular Advance

pnewhook writes "The New York Times is reporting that 'by reconstructing ancient genes from long-extinct animals, scientists have for the first time demonstrated the step-by-step progression of how evolution created a new piece of molecular machinery by reusing and modifying existing parts. The researchers say the findings, published today in the journal Science, offer a counterargument to doubters of evolution who question how a progression of small changes could produce the intricate mechanisms found in living cells.'"

    including evolution, if it exists.

    There is nothing without God. What is the difference between a man who is alive one second, and dead the next second. The very second life ends??? The soul!!

    The researchers found the modern equivalent of the stress hormone receptor in lampreys and hagfish, two surviving jawless primitive species. The team also found two modern equivalents of the receptor in skate, a fish related to sharks.

    After looking at the genes that produced them, and comparing the genes' similarities and differences among the genes, the scientists concluded that all descended from a single common gene 450 million years ago, before animals emerged from oceans onto land, before the evolution of bones.

    Now there is some circular logic? It is possible these existed exclusive of one another. These "scientists" are as credible as the Koreans who claimed to have cloned people.

    What happened was that a glitch produced two copies of the receptor gene in the animal's DNA, a not-uncommon occurrence in evolution. Then, for reasons not understood, two major mutations made one receptor sensitive just to cortisol, leading to the modern version of the stress hormone receptor. The other receptor became specialized for kidney regulation.

    And this does not show cause at all. It is possible everything existed. So what? They are claiming that God couldn't have made those enzymes, or the manner in which they function.

    We would not be here without God. He made everything, and the rules of the system. Our scientists are nothing more than looking at what God made and trying to understand how it works. Any scientist who denys God is not worthy of being a scientist.

  4. Cultural Evolution, and Nationalism Reborn,Anyone? by tjstork · · Score: 0, Troll

    The flipside of the evolutionary topic is, well, what if we just say there is no God and move on? Dismissing the existence of God in no way advances the human condition.

    Consider, why does one need to foolishly accept that a better adapted emergent species is not fundamentally better than a less adapted one? It's one thing to argue, correctly, that fossils form an evolutionary chain or that, we can witness the evolution of bacteria in near real time, but then to make the argument that because something is not as well adapted smacks of political correctness designed to avoid the obvious conclusion, that if some beings are better adapted than others, than humans must be too, and there ought to be scientifically determinable markers to measure which humans are better or which are worse. If we think macroscopically, we could also conclude that a culture forms an organism of sorts and different cultures evolve as well, with some naturally and deservedly displacing others, or, some others breeding weakness into a culture by virtue of exchange of information...

    Not that I would ever troll, if there is no God, what is actually wrong with Western domination of the world, or, in particular, the American invasion of Iraq and its goals to inject Democracy into the middle east. If it works, then, would that not prove American Democracy was superior, especially considering that only 130,000 soldiers are tasked to correct a nation of some 25 millions, and, if so, then, wouldn't it simply be as natural as one strain of bacteria emerging that is better adapted to say, penicillin, than another?

    Imagine there are two aeroplanes on the tarmac - one built with the theory of aerodynamics and the other with the hypothesis of evolution. Which one will you get into to fly from New York to Los Angles? I know which one I'm flying in. Evolution is just social science in disguise. It feels good to get jerked off but you have to come back to reality sometime...
