In other words, species in similar ‘niches’ are different taxa which have had different histories. Historical biogeography focuses on evolution — change in t

Adaptation can imagine an assemblage of slightly different situations, or environments, to which the animal would on the whole be less adapted; and equally in so far as we can imagine an assemblage of slightly different organic forms, which would be less well adapted to that environment” (Fisher, 1930).

Biogeography has evolved along the two avenues of pattern definition and process identification, principally from systematics, ecology

There is too little sound knowledge of biogeographical processes, reflected by disparity about what can be assumed or should be investigate

In the intervening hundred years, biogeographers, ecologists, and palaeontologists have identified many other spatial and tempor
