Proteins 2


To form proteins, amino acids must also be highly concentrated in an extremely pure liquid (c). However, the early oceans or ponds would have been far from pure and would have diluted amino acids, so the required collisions between amino acids would rarely occur (d). Besides, amino acids do not naturally link up to form proteins. Instead, proteins tend to break down into amino acids (e).

c. “It is difficult to imagine how a little pond with just these components, and no others [no contaminants], could have formed on the primitive earth. Nor is it easy to see exactly how the precursors would have arisen.” Francis Crick, Life Itself (New York: Simon and Schuster, 1981), p. 85.

d. “But when multiple biopolymers must all converge at the same place at the same time to collectively interact in a controlled biochemical cooperative manner, faith in ‘self-organization’ becomes ‘blind belief.’ No empirical data or rational scientific basis exists for such a metaphysical leap.” Abel and Trevors, p. 9.

e. “I believe this [the overwhelming tendency for chemical reactions to move in the direction opposite to that required for the evolution of life] to be the most stubborn problem that confronts us—the weakest link at present in our argument [for the origin of life].” George Wald, “The Origin of Life,” p. 50.
