tanding Natural Selection in the Garden Context What Is Natural Selection? Natural selection is the process by which individuals with certain heritable traits are more likely to survive and reproduce than those without those traits. Over generations, this leads to the a
selection as a universal, yet context-dependent, evolutionary mechanism. Pros and Cons of Focusing on a Garden Ecosystem Pros: 1. Accessibility for study and observation. 1. Repeatability of experiments and observations. 2. Clear visualization of ecolo
