How does an individual with a competitive advantage lead to the evolution of an entire species? Individuals that survive due to their competitive advantage are able to expand their range, similar to how the finches radiated out from one common ancestor on the mainland. Traits that are advantageous help certain individuals reproduce at higher rates, so those traits are more common within the population. Some individuals are better at competing for resources, and that allows them to survive droughts or other major ecological events, leading to the extinction of certain species and the survival of others. Those who have traits that help them survive are able to reproduce, and their offspring have those traits, leading to a change in the species over time.

Ecological adaptations

An ecological adaptation is any morphological, physiological, or behavioral trait of an organism that allows it to survive and reproduce in a habitat or ecosystem. Adaptation is a biological mechanism by which an organism gradually gets more acclimated to its surroundings.
