the ending doesnt make any sense. first of all, remember when mark was telling the apes what happened to the apes on earth. he said that they all died becuz humans cut down all of the trees they lived in thus becoming extinct. so when he returns to earth, going back in time like the device in his pod showed, where did the extinct apes on earth come from? he even said that the monkeys in the spaceship werent apes cause they were extinct already and that they were chimps and stuff. and as we all know, chimps cant morph into apes so even if they did crash land and overpower the humans, where did the apes come from? might as well have had dinosaurs or something when he returned to earth...
