With respect to the few inhabitants of small isld – if they do always belong to very diverse types in each class, we have to explain this, first assuming formerly land continuous; then it is clear that restricted conditions can best support very diverse types; if not continuous it shows that very many must be imported compared to those which can ultimately exist. With respect to endemic forms, by creationist simple act of creation, & giving again that very diverse forms are best supported of the same general types. According to my theory some of the diverse types have been modified into new forms.
Look to list of Kerguelen Land Plants & Auckland isld. & Norfolk Isd.
