Nearly 2.5 billion years of prokaryotic cells and nothing else – two-thirds of life’s history in stasis at the lowest level of recorded complexity… Why did life remain at stage 1 for two-thirds of its history if complexity offers such benefits? ~ Stephen Jay Gould 1941 to 2002 - Paleontologist
On the principle of successive variations not always supervening at an early age and being inherited at a corresponding not early period of life we can clearly see why the embryos of mammals birds reptiles and fishes should be so closely alike and should be so unlike the adult forms. ~ Charles Darwin 1809 to 1882 - Naturalist Evolutionary Biologist

Euclid’s work ought to have been any educationist’s nightmare… it never offers any “motivations ” it has no illuminating “asides ” it does not attempt to make anything “intuitive ” and it avoids “applications” to a fault. It is so “humorless” in its mathematical purism that… …it should have been spurned by students and “progressive” teachers in every generation. But it nevertheless survived intact all the turmoils ravages and illiteracies of the dissolving Roman Empire of the early Dark Ages of the Crusades and of the plagues and famines of the later Middle Ages. ~ Salomon Bochner 1899 – 1982 - Mathematician
