SURVIVAL OF THE FITTEST NOT THE ARRIVAL OF THE FITTEST :


SURVIVAL OF THE FITTEST NOT THE ARRIVAL OF THE FITTEST .
“… starting in the 1970s, many biologists began questioning its adequacy in explaining evolution. Genetics might be adequate for explaining microevolution, but microevolutionary changes in gene frequency were not seen as able to turn a reptile into a mammal or to convert a fish into an amphibian. Microevolution looks at adaptations that concern the survival of the fittest, not the arrival of the fittest. As Goodwin points out, ‘the origins of species—Darwin’s problem—remains unsolved.’ ”
Gilbert, Scott et al., Resynthesizing Evolutionary and Developmental Biology, Developmental Biology 173:357’372, 1996.

Yes , that deceptively named ( microevolution ) process that gives us the variation we have within living organisms will in no way get fish to fishermen , simpler cells to more complex cells , microbes to microbiologists .
This kind of change will only ever produce humans with variation , wolf with variation ie dogs , horses with variation , birds with variation etc .
