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 “glinozem”, 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?
