selection

Selection is the process by which certain individuals in a population have a better chance of surviving and reproducing because of favorable traits. Over time, these advantageous traits become more common, shaping the characteristics of the population. It’s a core mechanism of evolution, driven by differences in survival and reproductive success related to genetic traits. For example, animals might be selected for better camouflage because they’re less likely to be seen by predators, allowing them to thrive and pass on that trait to their offspring.
