Evolution through a scientist’s approach, an approach where evidence is examined and predictions made, hypotheses are proposed and tested. Along the way, many will applaud and many will object. But both reactions are inappropriate. Science as a discipline does not cheer for a given outcome of its experiments and investigations. But we will touch on enough detail to give a solid underpinning for the following conclusions. Common descent is a fact – all life on Earth is related through common ancestry. Changes within a single species occur – so-called microevolution. Species themselves come and go – so called macroevolution. The primary mechanism of change is genetic inheritance, with variation and natural selection.
