The Ribosome is perhaps the most complex machine at the centre of life. It is the place where proteins are assembled by putting together the 20 different amino acids in a specific order coded by information "photocopied" from the cell's "hard drives" - the DNA molecules.
Bruce Alberts is the President of the National Academy of Science in the US and organisation which thrown its weight behind the campaign to exclude consideration of Intelligent Design from Science.
In his huge textbook on Molecular and cellular biology he says this about the ribosome:
“The complexity of a process with so many interacting components has made many biologists despair of ever understanding the pathway by which protein synthesis evolved.”
He goes on to argue that RNA in the ribosome (the factory for assembling amino acids into long chains in the correct order using the code message copied from the DNA) provides a clue to its simple evolutionary precursors.
The important point is that Bruce Alberts here acknowledges a real and serious problem. He goes on to suggest some hope for Darwinists but it is a clutching at straws sort of hope.
Biologists have really serious problems with explaining complexity using chance and selection but they are determined to teach our children that no other more appropriate causes of complexity can be seriously considered.
