The new hypothesis of life complexity: There is mitochondria first and then have life complexity
On latest Nature, British the intersection of London University and the intersection of Nick and Wren with the intersection of Germany and Du Sene many William of husband university Martin, biologist of institute, propose one kind of or can explain animal and original grandfather of plant at the earth - -First " real core " Hypothesis that new that how the organic matter takes shape. This hypothesis thinks, the intersection of complicatedness and the intersection of cell and variety of life much, only can appear until one cell find, enter another route of cell and evolve mitochondria with time.
As to standard of today, the life on the earth is quite simple while appearing for the first time 4 billion years ago. More than 1 billion years, our earth is ruled by those and unicellular bacterium and microorganism more or less a bit similar humble bacterium and other organic matter groups of today. Then, only in more than 2 billion years ago, one new the intersection of life and form in primitive to flow in the thick liquid borning, this has represented a thoroughly different process evolves. Many cell lives which we know today (for example make the earth more beautiful Chinese sweet gum wood, mould, the mushroom, mouse or mankind of we,etc.) Variety be lasted kinds of organic matter, but know whether there are how not to begin to exist on earth on it yet scientist.
Mitochondria is a tiny particle which produces cellular capacity. Have hundreds of mitochondria in the cells of mankind and other animals, they are the health " The machine " From growing to extremely offering " The fuel " .
The new thinking contradicts with hypothesis in the past, the hypothesis before this thinks, before mitochondria appears, the complicated many cells organism took shape according to one's own strength at first. "Biologists have been thinking all the time, complexity is in the front, after mitochondria is here. " Martin says, " our research shows, this is impractical. Mitochondria is essential for complexity place " .
Mitochondrial development seems to only take place in the whole natural history of the earth a too only once. Biologist of U.S.A. north University of Illinois Neil and Blanc and Stone says, this is a very challenging step in the origin of life. But it find method, enter another enough to one cell even cell. The two have in a state of cooperating (called growing) Coexist, the shared resource is instead of vying each other, coexist but kill the other side.
The danger at the beginning is, internal cells will become a parasite, will cut a dash through fighting for resources with constellation chief cell, and killed the host finally. However, researchers say, such a thing has not happened, but two cells have evolved together. This internal cell is actually only more and more valid on a thing, that is to provide energy for cell, and it becomes smaller and smaller, losses all unnecessary genes for its emerging function.
Energy in the big cell getting sufficient to make new the intersection of life and form these gather, appear, have another more 1000 or more DNA quantity than the intersection of they and ancestor, allow them to become more and more complicated, form the plant, animal and other branches progressively as time goes on.
Researchers think, this kind of energy can explain why bacterium lacking these small energy factories and never complicatedness which become real of other cells too while studying. They face energy, restrain from always, prevent them from and win and use complicate hundreds and thousands of new genes needed. (Feng WeiDong)
