After Miller's death in 2007, scientists examining sealed vials preserved from the original experiments were able to show that there were actually well over 20 different amino acids produced in Miller's original experiments. That is considerably more than what Miller originally reported, and more than the 20 that naturally occur in life

[COPY]Miller’s experiment did produce the amino acids, but only by continuously circulating the reaction mixture and isolating products as they were formed. The quantities were still tiny and not in the same proportions as found in nature[/COPY].

Nobody really knows why the part of the brain that makes us unique
should have evolved so rapidly; tripling in size in less than two
million years. It certainly looks as though evolution entered a
positive feedback loop in which natural selection favouring creative
intelligence became linked to an ever more extravagant expression
of that intelligence

Although there is no watertight explanation for the runaway pace of
evolutionary change that human brain development would seem to
require, one of the more imaginative ideas is that our frontal brain
is an ornament required for courtship display. According to this
idea, the human brain is the product of the mutual preference of
men and women for mating with partners who display unusually
creative intelligence in the rituals of courtship. This can result in a
form of natural selection called sexual selection. It depends on
creativity in courtship and the large brain that it requires being
heritable traits. If the larger brained individuals were genetically
fitter specimens, which they may well have had to be to carry the
burden of an enlarged brain, sexual selection can provide an
explanation for the exaggerated size of the human cortex and
runaway pace of human brain evolution

A question that does not seem to be answered by the sexual
selection hypothesis, and requiring further examination, is the
reason for the late emergence of physical evidence of creative
intelligence. Human beings, with brains equal in cubic and
intellectual capacity to ours, first appeared in the fossil record more
than 250,000 years ago. If their brains attained cleverness and
creativity in the interests of seduction, why does significant proof of
creative intelligence, such as cave paintings, not appear until
just 35,000 years ago? This apparent discrepancy does not disprove the
role of sexual selection in the brain’s evolution, but suggests that it
must be part of a more comprehensive explanation for our
extraordinary brains. The truth is that we cannot yet explain why
we enjoy exercising them in the creation and public display of
music, art, poetry, and humour.
