All the evidence massively supports a theory of evolution that knits together everything we know about biology.

If you are fortunate enough to not live in Idiot America you should know that millions of American science deniers actually believe in the Noah's Ark genocide fantasy. Really. When I first encountered these retards I thought they were joking but now I know they really believe their fairy wiped out almost the entire human race. And even more pathetic, they worship this supernatural homicidal maniac.

I'm not making any of this up. Come to America and see the burning stupid for yourself. There's at least 100 million of these assholes who brainwash children and threaten biology teachers. Our Christians are scum, equal to terrorists, and they need to be wiped off this planet.

I want to write down the name of an anti-science post at another website that I visited recently. I'm putting it here. It was of course written by a full-of-shit god-soaked idiot.

These two comments are from another website. A person (Elroch) who knows what he's talking about writes about how life got a foothold on Earth.

100 codon sequences of DNA do not appear from scratch. This degree of complexity (and more) has been around for billions of years, passed down and evolving through reproduction, mutation and natural selection. The question is where this sort of level of complexity arose over 2 billion years ago. One thing is for sure: it did not arise by randomly selecting 100 codons and hoping exactly one particular sequence arises (This is the assumption made in your quote, and is the first abuse of statistics).

Life is about functional information. Modern life exists in a much harsher world than early life, because of the existence of millions of other highly evolved organisms. Early life had little competition.  The earliest life had no competition at all and a rich source of chemicals including amino acids, nucleic acids and several sources of energy.

As a result, early life must certainly have been based on a much smaller amount of information. All that is necessary is for there to have been some mechanism for this information to replicate in the environment at that time. A likely candidate for an early (but not the first) vehicle for this information is free RNA molecules in a complex soup of chemicals that was the environment. It is not necessary for this precursor of life to have been in any sense enclosed -  this is because the environment was so different. All that is necessary is that there was some set of molecules which, in combination in that environment acted to replicate all of themselves. This is known as anautocatalytic network. Early networks very likely included small RNA chains and small peptides. Still earlier ones probably may have had something even simpler. It doesn't matter that the individual units had only a small amount of functionality, it is the total functionality that matters, since replication in the total environment is what matters.

Natural selection and evolution immediately became effective the first time that some information carrying molecule (such as an RNA chain) was in an environment that led to its replication. This is because some errors inevitably occurred in the replication and these errors led to variation, and natural selection applied to this variation, by only preserving the molecules which best replicated themselves (and this must have been dependent on which molecules best assisted the other molecules which were involved in their replication).

Anyhow, the bottom line is that the earliest precursors of life could have had small amounts of information, not 100 codons. There were almost unimaginable numbers of these molecules in existence for what could have been hundreds of millions of years and one combination of them became a viable replicator. At some time the cell, DNA and other features arose by natural selection, by it being advantageous to the replication of some of the molecules in the network. At a later stage the cell nucleus arose in one branch of life (the eukaryotes), while it never arose in another (the prokaryotes). The evolution of these cells has led to all the life we see today.

There is still much to be understood better, and the scientific method is the appropriate method to do so, based on its track record of continual success.

It is not necessary to understand all the technicalities of this topic (I certainly don't) to see that the information viewpoint on life throws additional light on why the process works.

But let me express the salient points of the information view of life in a way that requires no expert knowledge.

• Life is essentially a vehicle for functional information, which gets passed from generation to generation almost perfectly, so that enough copies of the information are viable
• There are many ways in which random changes can be made to this information, which can not only modify the information in genes but also add, duplicate, remove, cut, merge or rearrange genes, and add, duplicate, remove, divide and merge chromosomes
• Variations that are disadvantageous quietly disappear, advantageous ones become more numerous, neutral ones add to the range of variation for future evolution
• Such small steps permit changes that span the entire tree of life over a long enough period of time and a large enough number of steps
• Prior to the existence of even the first single-celled organisms that are the common ancestor of all life, there must have been a precursor to life that involved simpler functional information that replicated itself. The evolution of this information led to the first cellular life.
