Hey! Where's the Beef?


2/10/2019

Everything in biology is done with statistical analysis.  If you want to know if something is true you begin by gathering data and then analyzing the data to determine if what you have indicates something that could not happen by chance.  For example, if a gene seems to be associated with a particular disease an attempt will be made to take the observed correlation and subject it to a statistical test in order to determine the probability that the correlation could occur by chance.  Generally a probability of 5% or less of the numbers occurring by chance is required to be relatively certain of causality. 

I wonder if any aspect of hypothesis testing has ever been applied to a functional gene arising by chance even given millions of years, or to the spontaneous creation of life in a sea of chemicals, or of a functional gene or proto-gene appearing by chance in one individual, surviving and spreading through the population, or the probability that the gaps in the fossil record are simply a factor of having overlooked them.  If  there are, I have not heard of them.  The theory of evolution is the one area of biology exempt from genuine statistical analysis.
