Some would be said to have more action than the others- but they all are really good movies.
to survive better
Survive and reproduce.
Over the years, the Abyssinian had adapted to become more intelligent and its fur has changed to a light brown color. This helps it blend in better with its surroundings.
It was replaced by bigger and better plants. Cooksonia was very primitive and could only live in a narrow set of conditions. Like many other extinct organisms, it was out-competed by organisms that were better adapted and had better methods of survival.

Water is pretty much the same in all times and places. Jurassic water would have been somewhat purer than today's, thanks to human pollution, but not significantly better than water in North America before Columbus. As for microbes and plant matter, those would have been slightly different, but the impact would be much the same: i.e., those animals that lived locally would have been adapted to them, those that had recently moved in would have have the reptilian equivalent of Montezuma's Revenge. As for the fish, there are a couple of possibilities. One is that since there was more oxygen in the air, there might have been more dissolved in the water as well. However, water has a finite carrying capacity for atmospheric gases. Also, since the planet as a whole was warmer, the water might have had LESS oxygen than it does today.
adaptations is the change in a species to help it to become better suited to its environment. these include structural, physiological and behavioral adaptations. limpets have adapted to survive on rocks and eat bird poos.
The process by which individuals that have favorable variations and are better adapted to their environment survive and reproduce more successfully than less well adapted individuals is called natural selection. This is part of Darwin's theory.
A new and better adapted species.
