intermediate intermediate 1860 1861 1866 1869 1872 | interme- diate 1859 |
varieties will be liable to accidental extermination; and during the process of further modification through natural selection, they will almost certainly be beaten and supplanted by the forms which they connect; for these from existing in greater numbers will, in the aggregate, present more
variation, variation, 1859 1860 1861 1866 1869 | varieties, 1872 |
and thus be further improved through natural selection and gain further advantages. |

Lastly, looking not to any one time, but to all time, if my theory be true, numberless intermediate varieties, linking
most most 1859 1860 | most 1861 1866 1869 1872 |
closely
all the species of the same group together, all the species of the same group together, 1859 1860 1861 |
together all the species of the same group, 1866 1869 1872 |
must assuredly have existed; but the very process of natural selection constantly tends, as has been so often remarked, to exterminate the
parent-forms parent-forms 1860 1861 1866 1869 1872 | parent forms 1859 |
and the intermediate links. Consequently evidence of their former existence could be found only amongst fossil remains, which are preserved, as we shall
in a future chapter attempt to show, in in a future chapter attempt to show, in 1859 1860 1861 1866 1869 |
attempt to show in a future chapter, in 1872 |
an extremely imperfect and intermittent record. |

It has been asked by the opponents of such views as I hold, how, for instance,
a land carnivorous animal could a land carnivorous animal could 1859 1860 1861 1866 1869 |
could a land carnivorous animal 1872 |
have been converted into one with aquatic habits; for how could the animal in its transitional state have subsisted? It would be easy to show that
