large sense, simultaneous, succession of the same forms of life throughout the world, accords well with the principle of new species having been formed by dominant species spreading widely and varying; the new species thus produced being themselves
owing to

had some advantage over their

over other
again spreading, varying, and producing
→new species. The
which are beaten and which yield their places to the new and victorious forms, will generally be allied in groups, from inheriting some inferiority in common; and
as new and improved groups spread throughout the world, old groups
disappear from the world; and the succession of forms

| There is one other remark connected with this subject worth making. I have given my reasons for believing that
our

deposited during periods of subsidence; and that blank intervals of vast

during the periods when the bed of the sea was either stationary or rising, and likewise when sediment was not thrown down quickly enough to embed and preserve organic remains. During these long and blank intervals I suppose that the inhabitants of each region underwent a considerable amount of modification and extinction, and that there was much migration from other parts of the world. As we have reason to believe that large areas are affected by the same movement, it is probable that strictly contemporaneous formations have often been accumulated over very wide spaces in the same quarter of the world; but we are
from having any right to conclude that this has invariably been the case, and that large areas have
