Darwins theory of natural selection of salamanders?

Darwin's theory of natural selection suggests that species evolve over time through the process of differential survival and reproduction. In the case of salamanders, variations in traits such as coloration, size, and habitat preference can influence their ability to evade predators and find resources. Those individuals with advantageous traits are more likely to survive and reproduce, passing these traits to future generations. Over time, this can lead to adaptations that enhance their fitness in specific environments.
