The same protein's left- (L) and right- (D) handed
isomers. The proteins in living creatures consist
only of left-handed amino acids.
Moreover, this characteristic of proteins makes the problem facing evolutionists with respect to "chance"
even worse. In order for a "meaningful" protein to be generated, it is not enough for the amino acids to be pre-
sent in a particular number and sequence, and to be combined together in the right three-dimensional design.
Additionally, all these amino acids have to be left-handed: not even one of them can be right-handed. Yet there
is no natural selection mechanism which can identify that a right-handed amino acid has been added to the se-
quence and recognize that it must therefore be removed from the chain. This situation once more eliminates for
good the possibility of coincidence and chance.
The Britannica Science Encyclopaedia, which is an outspoken defender of evolution, states that the amino
acids of all living organisms on earth, and the building blocks of complex polymers such as proteins, have the
same left-handed asymmetry. It adds that this is tantamount to tossing a coin a million times and always get-
ting heads. The same encyclopaedia states that it is impossible to understand why molecules become left-
handed or right-handed, and that this choice is fascinatingly related to the origin of life on earth. 212
If a coin always turns up heads when tossed a million times, is it more logical to attribute that to chance, or
else to accept that there is conscious intervention going on? The answer should be obvious. However, obvious
though it may be, evolutionists still take refuge in coincidence, simply because they do not want to accept the
existence of conscious intervention.
A situation similar to the left-handedness of amino acids also exists with respect to nucleotides, the small-
est units of the nucleic acids, DNA and RNA. In contrast to proteins, in which only left-handed amino acids are
chosen, in the case of the nucleic acids, the preferred forms of their nucleotide components are always right-
handed. This is another fact that can never be explained by chance.
In conclusion, it is proven beyond a shadow of a doubt by the probabilities we have examined that the ori-
gin of life cannot be explained by chance. If we attempt to calculate the probability of an average-sized protein
consisting of 400 amino acids being selected only from left-handed amino acids, we come up with a probability
of 1 in 2 400 , or 10 120 . Just for a comparison, let us remember that the number of electrons in the universe is esti-
79
mated at 10 , which although vast, is a much smaller number. The probability of these amino acids forming
the required sequence and functional form would generate much larger numbers. If we add these probabilities
to each other, and if we go on to work out the probabilities of even higher numbers and types of proteins, the
calculations become inconceivable.
