Scientists entirely baffled on the formation of the gene protein link
(Facts About Evolution)
None has ever been recreated in the laboratory, and the evidence supporting them all \being produced by random chance in the primitive environment\ is very thin. The emergence of the geneprotein link, an absolutely vital stage on the way up from lifeless atoms ...

Evolutionary theories of genetic machinery are unfettered by the facts
(Facts About Evolution)
evolution of the genetic machinery is the step for which there are no laboratory models; hence we can speculate endlessly, unfettered by inconvenient facts."— R. Dickerson, "Chemical Evolution and the Origin of Life," in Scientific American, September 1978, p. 70. Other related topics ...

No probability of randomly forming DNA
(Facts About Evolution)
Based on probability factors . . any viable DNA strand having over 84 nucleotides cannot be the result of haphazard mutations. At that stage, the probabilities are 1 in 4.8 x 10 50 . Such a number, if written out, would read: 480,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000. "Mathematicians agree ...

Characteristics are controlled not in a single place but by multiple genes
(Facts About Evolution)
However it gradually emerged that most characters, even simple ones, are regulated by many genes: for instance, fourteen genes affect eye color in Drosophila. (Not only that. The mutation which suppresses 'purple eye' enhances 'hairy wing,' for instance. The mechanism is not understood ...

Living cells store and operate on information like tiny computers
(Facts About Evolution)
All this is strikingly similar to the situation in the living cell. For discs or tapes substitute DNA; for 'words' substitute genes; and for 'bits' (a bit is an electronic representation of 'yes' or 'no') substitute the bases adenine, thymine, guanine and cytosine."— \ Fred Hoyle and C. Wickramasinghe, Evolution ...
