Stem Quotes - page 4
It is not within our province to inquire by what process, and in what condition the Almighty brought matter into existence-what the space was which it occupied, or what the forms were which it assumed. Of such things we know nothing. In the depths of primeval time, the globe we inhabit may have a planetary existence, wheeling along its ethereal railway without a breathing passenger to count its periods, and without a living plant to measure the day by its opening and closing blossoms, or to mark the rolling seasons by the yearly increments of its stem. Or it may have been the theatre on which vast cycles of animal and vegetable life have been run- now its birthplace, and now its grave: But we have no data to guide us in our conjectures, and even imagination fails us if we call it to our aid. Whatever may have been, had ceased to be at the commencement of our history, when the primary rocks, forming the moten nucleus of the globe, were first exposed to the action of the elements.
David Brewster
Although random mutations influenced the course of evolution, their influence was mainly by loss, alteration, and refinement... Never, however, did that one mutation make a wing, a fruit, a woody stem, or a claw appear. Mutations, in summary, tend to induce sickness, death, or deficiencies. No evidence in the vast literature of heredity changes shows unambiguous evidence that random mutation itself, even with geographical isolation of populations, leads to speciation.
