ORIGIN OF LIFE









One of the theories for the origin of life on Earth is the “primordial soup“ theory of the Russian biologist Oparin. It also assumes that wildlife has emerged from the so-called “koacervats” - some intermediate stage between inanimate matter and living cells.

In continuation of this teaching was made famous by Stanley Miller's experience to obtain the protein in the laboratory.

Its essence: a more complex substance formed from the most simple: NH3 (ammiac), CH4 (methane) and H2O (water vapor) under the influence of high temperatures and electric shocks. It was alleged that a living cell.

However, there are a number of objections:

1. Not those source materials

Connection of these substances could not be sustained.

The original substances. As is well known, ammonia breaks down under the influence of ultraviolet rays, and the consequence of methane, which was supposed to “alumina”, actually there.

2. Not those conditions

Such connections atmospheric oxygen destroys and, according to Miller, at the time of its synthesis in the atmosphere were not. It is not true, therefore, that a considerable depth found oxide stones, Earth's atmosphere was rich in oxygen.

Electrical discharges, used the experience in reality had to be not only just, but more and more connections and thus destroy built them.

3. Not the result

Miller received only a few amino acids, and as left-writhed, which are proteins, and right-writhled - it one is enough to break the connection. In other words, was not living matter and poisonous mixture.

And last objection: while the experience made Miller's mind, which in many ways is not allowed the destruction of the he molecules. Evolution same teaches that everything arose by itself as a result of a confluence of circumstances.

The theory was also launched “panspermia“ living cell is brought to Earth from another world, where all the conditions as in Miller's experience (no oxygen, many meta-and ammonia and high level radiation).

But it runs counter to the theory of probability.

And besides, if so, in what way is the cage was “listed“ here?
