individual species with with of the following characteristicts would be most likely to survive according to darwin

the smallest number of offspring
variations best suited to the environment
characteristics to their parents aquired by use and disuse
undergone mutations

Variations best suited to the environment. Darwin's theory of natural selection suggests that organisms with variations or traits that are best suited to their environment are more likely to survive and pass on those favorable traits to their offspring. This concept is known as "survival of the fittest." Therefore, individual species with variations that make them better adapted to their environment are more likely to survive and reproduce.
