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.
