Is it philosophical, is it quite allowable, to assume without evidence from fossil plants that the family or any of the genera was once larger and wide spread? and occupied a continuous area?
Splitting and gradual divergence of genera is exemplified very well and in a large variety of organisms.
The close relationship between railroad expansion and the genera development and prosperity of the country is nowhere brought more distinctly into relief than in connection with the construction of the Pacific railroads.

I accept extinction as best explaining disjoined species. I see that the same cause must have reduced many species of great range to small, and that it may have reduced large genera to so small, and of families.
La televisión no es sólo instrumento de comunicación; es también, a la vez, , un instrumento «antropogenético», un que genera un nuevo , un nuevo tipo de ser humano.

If about a dozen genera of birds had become extinct or were unknown, who would have ventured to have surmised that birds might have existed which used their wings solely as flappers, like the logger-headed duck (Micropterus of Eyton); as fins in the ...
