Anybody who believes that the earth is less than 10,000 years old needs psychiatric help.

The meaning of this observation is unclear, but it raises the unfortunate possibility of ambiguous triplets; that is, triplets which may code more than one amino acid. However one would certainly expect such triplets to be in a minority.

This seems highly likely, especially as it has been shown that in several systems mutations affecting the same amino acid are extremely near together on the genetic map.

Avoid the temptation to work so hard that there is no time left for serious thinking.

My own prejudices are exactly the opposite of the functionalists': "If you want to understand function, study structure".

One of the most frightening things in the Western world, and in this country in particular, is the number of people who believe in things that are scientifically false. If someone tells me that the earth is less than 10,000 years old, in my opinion he should see a psychiatrist.

Evolution is cleverer than you are.
