Individuals drawn from an "original" species could be out-competed in terms of overall survivability by slightly variant individuals. Such variance would thereby be re-inforced and tend towards the emergence of one or more separate species.

Where dramatically out-competed the original ancestor species could even be forced into extinction. A related group of well-adapted variant species could, in time, constitute a new Genus of emergent species.

In it was very much the case that most people in the westernised world would have thought that each species existed as a result of its being Created by God. Whilst those involved in Natural History studies had initiated systems of classification where individual species which bore strong similarities to each other were "grouped" and regarded as being members of the same Genus, such grouping was based on observable close, and presumably "God ordained," similarities themselves rather than on an explicit acceptance of "biological" relatedness.

If we suppose the amount of change between each horizontal line in our diagram to be excessively small, these three forms may still be only well-marked varieties; or they may have arrived at the doubtful category of sub-species; but we have only to suppose the steps in the process of modification to be more numerous or greater in amount, to convert these three forms into well-defined species: The final paragraph of this chapter summary reads: I believe this simile largely speaks the truth.
