The evolution theory . flint-skeleton of a Radio-larian. But if any spot of the capsule can vary by itself alone, may^ Zehnder, Die Entstelnmg des Lebens, 1899. 218 THE EVOLUTION THEORY not numerous other points in the animal also be hereditarily de-terminable ? With such complexity of the invisible structure it wouldnot greatly surprise us if* we should find amphimixis occurring in allunicellular organisms, and in many of them at a high level of elabora-tion. These apparently lowly and simple organisms are obviously veryfar from being the lowliest and simplest, as we shall discover laterin a different connexion. But that amphimixis is found as a periodi-cally recurring process even among these, must depend upon thefact that here too the preservation of the best-adapted structure, aswell as adaptability to new conditions, requires that the best variantsof many different parts of the cell should be brought together, andsince the hereditary substance lies in the ids of the luicleus, the union.
