The individual organisms that make up a population vary in the traits they possess, such as their size and shapes.
What does heritability refer to?
Genetic traits that lead to structural features passed on to offspring.
What is differential reproduction?
Many more offspring are produced than can possibly survive, leading to some individuals surviving long enough to reproduce.

Study Notes
Darwin's Four Postulates
- Variation exists among individuals in a population, impacting traits such as size and shape.
- Heritability refers to genetic traits that can be passed down to offspring; for example, tall parents often have tall children.
- Differential reproduction occurs when more offspring are produced than can survive, leading to only certain individuals reproducing successfully.
- The frequency of traits can change from generation to generation; natural selection favors individuals with advantageous heritable traits, leading them to produce more offspring.
