Irreducibility



Irreducible Complexity - cohesion

The last problem we're going to look at, is the problem of irreducible complexity. Not only the components of the cell turn out to be that each individuals are very unlikely, but it's unlikely that these components are self-assembled to form complex structures. The term irreducible can be illustrated with the simple example of the mousetrap: each component is needed for the functioning of the whole. Take one part away and the mousetrap does not work anymore. This makes it much harder to figure out how such a thing could have arisen gradually, after all: add the direct path of each single component is impossible: it must therefore indirectly.


Mousetrap

Now prove some structures and mechanisms in the cell such irreducible composition of many highly specific (and unlikely) proteins. This reduces the chance unreasonably small that the Neodarwinistisch interplay of chance and natural selection, this brings about . One can compare it to someone blindfolded and deaf motorway crossing: what is the probability that he will not get run over? This obviously depends on the hustle and bustle of traffic, but also the number of lanes that he must cross so. If it all happen with some 3 lanes, but when there are to be a 1000 lanes to be crossed, this probably will become a lost cause. Similarly, for the chance origin of the numerous biochemical irreducible structures in living cells this is equal.

To have an idea of what is going on in the cell, one can compare it to a real city. In that city are constantly made all kinds of building materials, and according to rules which are copied from the central library. In this library, the source documents are constantly carefully proofread for errors and, if improved. Energy plants ensure the production of the necessary energy. All kinds of goods trains on rails drive back and forth with materials that are provided with an indication of the destination. Old materials are fed to a special place in order to be recycled there. And much more ... And if that's not enough, the whole city can copy itself in a few hours completely.

The most notable probably is the ribosome complex which proteins are synthesized but which itself consists of about 50 proteins. This is a very large 'chicken and egg' problem. As the neo-Darwinism is based on self-reproduction, to find an explanation for the emergence of self-reproduction is a very hard nut to crack.

So the cell shows a surprisingly complex system - full of irreducibly complex subsystems - for which by chance seems extremely unlikely.
