Study Notes
Natural Selection Overview
- Natural selection acts as a mechanism for evolution, favoring traits that enhance survival and reproductive success.
- Organisms with beneficial traits are more likely to reproduce and pass those traits to the next generation.
False Statement About Natural Selection
- A common misconception is that natural selection always leads to perfection; however, it only leads to adaptations that suit current environmental conditions.
Impact of Natural Selection on Traits
- Natural selection shapes an organism's traits by promoting genetic variations that provide advantages in a specific environment.
- Traits that increase survival rates, such as camouflage or resistance to disease, are more likely to be inherited.
Consequences Over Generations
- Over many generations, natural selection can lead to significant shifts in the traits of a population, potentially resulting in speciation.
- Constant environmental changes can push a population to adapt or face extinction.
Outcomes of Natural Selection
- The primary outcome of natural selection is increased prevalence of advantageous traits within a population.
- It can also lead to decreased genetic diversity if only a few traits dominate due to selection pressures.
