Capitolo 7

pines ever came to diversify my valleys of island. The seeds that did
I/you/he/she contact at times really us it belonged rather to one or other of
four special classes. Or they was very small and they turns on, as the
spores of ferns, act, and baton-musks;  or they flies and
feathered, as tooth of lion and thistle-feather;  or they was the stones of
fruits that I/you/they have eaten from birds, as pink-also and hawthorn;  or them
it was chaffy it granulates, included in papery staircases as grasses and sedges,
well of some kind adapted to quickly be borne on the surface of the water.
In all these ways to which cried new they have really been diffused from slow degrees
the islands;  and if theirs were of son-in-laws suited for the climate that they is grown
and it bloomed, while the first growth of ferns and flowerless living down
grasses in the rich valleys.

The time with which taken to people my archipelago this various
plants were, clearly, when he/she judged from Your human standards, immensely
long, as often the group only an only new sum received in the
error of two or three centuries. But I observed a very curious result
of this accident and long way of provision the country:  some of the
plants that arrived the first, while having entirely the coast clear to
them, free from the fierce competition to which you/they always had them
is exposed on the continent of Europe, it started to play a great quantity in
various directions, and acts on here from new conditions, soon
presumed under stress of natural selection totally separate specific
forms. (You see, I have dominated completely Your better modern scientific
dictionary.) For example they were not, for first any bugs of some kind
on the islands;  and so those plants that depended for them in Europe
fertilisation on bees or butterflies or they had here for adapting
them somehow to the wind as a messenger of their pollen otherwise to
dies out for lack to cross. Again, the number of enemies to be
meeting place to a minimum, these first plants extended to various losing
defenses or protections that they had acquired on the continent against snails
