What is Impossible in Evolution?
Be Smart・2 minutes read
Certain traits are absent in nature due to physical limitations, like animals not having wheels as body parts. Environmental factors influence adaptations, as seen in the disappearance of wheeled vehicles in favor of camels in some regions.
Insights
- Evolutionary constraints prevent the development of traits like wings for humans, as each stage of evolution must be advantageous, showcasing how the fitness landscape concept influences trait evolution.
- The concept of "forbidden phenotypes" in evolution, such as animals with wheels as body parts, highlights how physical limitations and environmental factors shape the evolution of traits, as seen in the absence of certain impossible phenotypes like laser-turret-wielding zebras or live-birth birds, illustrating the unique adaptability and creativity of evolution.
