It is generally accepted that present-day animals and plants differ from those of the

Darwin assumed that the ancestors of all (12) ................ types had been blown to the islands in bleak weather, had survived and changed somehow (13) ................ the various forms. In the years after the voyage, Darwin gradually came to the conclusion that individuals better suited (14) ................ their environment would tend to leave more offspring while those (15) ................ well adapted would die out.
