And preservation of the bacterial colony as a whole, the paper notes, would keep beneficial mutations
in the gene pool.
Abruptness is the rule for all life forms, and this is abominable to those who believe in macroevolution because they need to find a glacially slow accumulation of beneficial mutations
on directed mutagenesis in certain bacteria belittles the importance of natural selection in the evolutionary process particularly because no one expected that beneficial mutations
could be induced from within the cell.
Jardine then generated libraries that contained all possible combinations of beneficial mutations
, resulting in millions of mutants, and screened them using techniques called yeast surface display and FACS.
Drift can haphazardly make a detrimental gene prominent in a population, or accidentally eliminate beneficial mutations
