#redirect[[Evolution by natural selection]]
 
For natural selection says that all variations are selected for environmental fitness. This, you would think, stands to reason (is ''[[a priori]]'' true); for if it were not, and a variation that ''prejudiced'' one’s environmental fitness could sometimes win out in the genetic lottery, then the reliable [[algorithm]] of incremental, and inevitable, ''improvement'' of a species’ capacity to cope with prevailing conditions would be, in a word, buggered.
 
A successful variation which prejudices a species’ ability to survive and replicate, would ''[[falsify]]'' the theory of evolution by natural selection, you would think.
 
Yet, this is exactly what sexual selection purports to do: explain the prevalance of “peacock’s tails” in the genetic record — biological adaptions which confer no survival benefit at all, and indeed, seem to make survival harder. Such as a male peacock’s tail.
 
There is a theory that the client alert has survived in the great ecosystem of ideas, despite it being read by absolutely no-one except the poor sod commissioned to put it together, and his supervising associate, by dint of some kind of analogue to sexual selection.
