Until recently , a gene was defined as a DNA sequence that codes for a
polypeptide , but we may now argue whether or not introns count as part of genes
, or whether the term gene should also embrace nontranslated regulatory regions

Eldredge and Gould ( 1972 ) and Stanley ( 1975 ) went on to argue that because
individual species are static , long - term trends in morphology are the
consequence not of anagenetic change within single lineages , but of selection
among ...
