Individuals with traits that increase their survival and reproduction will leave more offspring than individuals with traits that decrease their survival and reproduction.
Here's why:
* Differential reproductive success is the core concept. It means some individuals within a population reproduce more successfully than others.
* Traits are the characteristics that contribute to an individual's survival and reproduction. These traits can be physical, behavioral, or physiological.
* Survival and reproduction are the ultimate goals of natural selection. Individuals that survive longer and reproduce more are more likely to pass on their traits to the next generation.
This postulate highlights the direct link between the traits an organism possesses and its ability to leave more offspring. Those with advantageous traits are more likely to survive, find mates, and produce offspring, leading to the spread of those traits over time.
