Phenotypic characteristics and Phenotypic changes

WebGradualism: A long time ago, there were a lot of tiger-like animals, but without stripes. Most of them were unmarked, but a few had light markings and color variation in their fur. These few blended in with the tall grasses a little bit better, so they were generally able to catch more food, and fewer of the marked than unmarked ones died of ... WebFurthermore, gradualism is a more realistic view when looking at speciation as compared to punctuated equilibrium. Disruptive selection can initially rapidly intensify divergence; this is because it is only manipulating alleles that already exist. Often it is not creating new ones by mutation which takes a long time. is it commonsense or common sense
