How did natural selection most likely result in this evolutionary change?

Natural selection likely drove this evolutionary change by favoring individuals with traits that improved their survival and reproductive success in a specific environment. Those individuals with advantageous adaptations were more likely to survive, reproduce, and pass those traits on to their offspring. Over generations, these beneficial traits became more prevalent in the population, leading to the observed evolutionary change. This process illustrates how environmental pressures can shape the traits of a species over time.
