Josiah wanted Ben to attend school with the clergy, but only had enough money to send him to school for two years. He attended Boston Latin School but did not graduate; he continued his education through voracious reading. Although "his parents talked of the church as a career" [13] for Franklin, his schooling ended when he was ten.

Acknowledgements Introduction Every so often, someone comes up with the statement "the formation of any enzyme by chance is nearly impossible, therefore abiogenesis is impossible".


Often they cite an impressive looking calculation from the astrophysicist Fred Hoyle, or trot out something called "Borel's Law" to prove that life is statistically impossible. These people, including Fred, have committed one or more of the following errors.

Glossary An enzyme or ribozyme that synthesizes peptides.

Weinstein effect - Wikipedia

An enzyme or ribozyme that adds a monomer to a polymer, or links two shorter polymers together. Any single subunit of a polymer. An amino acid is a monomer of a peptide or protein, a nucleotide is a monomer of an oligonucleotide or polynucleotide.

Adenine, Guanine, Cytosine and Uracil. These are the monomers that make up oligo- or polynucleotides such as RNA.

A short polymer of nucleotide subunits. A enzyme or ribozyme that makes a polymer out of monomers. A biological catalyst made from RNA. A molecule which can make an identical or near-identical copy of itself from smaller subunits.

At least four self-replicators are known. Problems with the creationists' "it's so improbable" calculations 1 They calculate the probability of the formation of a "modern" protein, or even a complete bacterium with all "modern" proteins, by random events.

This is not the abiogenesis theory at all. I will try and walk people through these various errors, and show why it is not possible to do a "probability of abiogenesis" calculation in any meaningful way. This is then cranked up by adding on the probabilities of generating or so similar enzymes until a figure is reached that is so huge that merely contemplating it causes your brain to dribble out your ears.

This gives the impression that the formation of even the smallest organism seems totally impossible. However, this is completely incorrect. Firstly, the formation of biological polymers from monomers is a function of the laws of chemistry and biochemistry, and these are decidedly not random.

Secondly, the entire premise is incorrect to start off with, because in modern abiogenesis theories the first "living things" would be much simpler, not even a protobacteria, or a preprotobacteria what Oparin called a protobiont [ 8 ] and Woese calls a progenote [ 4 ]but one or more simple molecules probably not more than subunits long.

These simple molecules then slowly evolved into more cooperative self-replicating systems, then finally into simple organisms [ 251015, 28 ]. An illustration comparing a hypothetical protobiont and a modern bacteria is given below. The first "living things" could have been a single self replicating molecule, similar to the "self-replicating" peptide from the Ghadiri group [ 717 ], or the self replicating hexanucleotide [ 10 ], or possibly an RNA polymerase that acts on itself [ 12 ].

Another view is the first self-replicators were groups of catalysts, either protein enzymes or RNA ribozymes, that regenerated themselves as a catalytic cycle [ 35152628 ]. An example is the SunY three subunit self-replicator [ 24 ]. These catalytic cycles could be limited in a small pond or lagoon, or be a catalytic complex adsorbed to either clay or lipid material on clay.

Given that there are many catalytic sequences in a group of random peptides or polynucleotides see below it's not unlikely that a small catalytic complex could be formed.

These two models are not mutually exclusive. The Ghadiri peptide can mutate and form catalytic cycles [ 9 ].

No matter whether the first self-replicators were single molecules, or complexes of small molecules, this model is nothing like Hoyle's "tornado in a junkyard making a ". Just to hammer this home, here is a simple comparison of the theory criticised by creationists, and the actual theory of abiogenesis.

Note that the real theory has a number of small steps, and in fact I've left out some steps especially between the hypercycle-protobiont stage for simplicity.Both articles talk about the same topic male-female communication.

Every so often, someone comes up with the statement 'the formation of any enzyme by chance is nearly impossible, therefore abiogenesis is impossible.' Often they cite as evidence an impressive-looking, but ultimately erroneous, probability calculation.

Game theory is the study of the ways in which interacting choices of economic agents produce outcomes with respect to the preferences (or utilities) of those agents, where the outcomes in question might have been intended by none of the meaning of this statement will not be clear to the non-expert until each of the italicized words and phrases has been explained and featured in some.

The Weinstein effect is a global trend in which people come forward to accuse famous or powerful men of sexual misconduct. The term came into use to describe a worldwide wave of these allegations that began in the United States in October , when media outlets reported on sexual abuse allegations against film producer Harvey allegations were described as a "tipping point" or.
