"Phylogeny" Quotes from Famous Books
 ... more than one museum. "So we are taught; but try to reconstruct the steps in their evolution and you realise your hopeless ignorance" (M., p. 11). If we cannot construct a "tree" for fowls, how absurd to adventure into the deeper recesses of Phylogeny. If all that Professor Bateson says is true, is not Driesch right when he speaks ...

... series of strata, marking periods of intervening time which there is no means of measuring, but during which we know that the progress of change in the animals then living never ceased. When such a break is reached, the course of phylogeny is like picking up an interrupted trail, with the additional complication that the one we find is never quite like the one we left, and it is in such conditions that the systematist must apply his knowledge of the general progressive tendencies through the ages of change, ...

... organs of the type found in fishes, and this can only be explained on the assumption that they are descended from aquatic fish-like ancestors.
