On page 14 it said that ¨Buck and Spitz started fighting". This was Bucks and Spitz first fight. I think that it is survival of the fittest because Buck was the one who started fighting.
Buck and Spitz second fight.
On page 8 it said that "the man in the red sweater was waiting to meet Buck for the first time." Buck was not excited to meet the man in the red sweater. I think it survival of the fittest because that is when Buck and the man in the red sweater met
When Spitz was the leader
On page 64-65 it said that ¨Buck started dreaming about when he used to be with Miller and his kids.¨ He remembers about his aunt sisters inside the cave.¨
Buck and John Thornton at the bar place
On page 41 it said that "Buck had taken Spitz spot the next day." Buck and Spitz were fighting just for a animal and that Buck won. I think that Buck was survival of the fittest because Buck got revange of Spitz.
In the beginning of chapter 2 it said that ¨the dogs were good and that Spitz was still the leader. I think that it is survival of the fideast because the dogs payed attention and the dogs listened to what the guy said.
In chapter 6 it said that "Buck and John Thornton went to a bar and there was Nig but Buck couldn't get near Nig so Buck just kept on look at him from a far distance and Nig went close to John Thornton and Buck went and went for Nig and it was kinda bad for Buck and John Thornton." I think it it survival of the fittest because Buck went to help John Thornton.
