No, humans will not evolve to fly.
The dream of humans soaring through the skies has been a long-held fantasy. However, according to current scientific understanding and the provided reference, the evolution of human flight is considered virtually impossible. This conclusion stems from several key factors, primarily the lack of selective pressure necessary to drive such a dramatic evolutionary shift.
Why Human Flight Evolution Is Unlikely
| Factor | Explanation |
|---|---|
| Lack of Selective Pressure | For a trait like wings to evolve, there would need to be a significant advantage for individuals with proto-wings compared to those without. There's no current environmental pressure to provide this advantage for humans. |
| Complex Biological Changes | Developing wings would require substantial changes to our skeletal structure, muscle distribution, and overall physiology. This includes:

What Would Be Necessary for Flight Evolution?
The reference material points out the necessity of selective pressure favoring the development of proto-wings, which simply isn't present. Here's what such a scenario might look like (though highly improbable):
- Environmental Necessity: A situation where ground-based movement becomes detrimental (e.g., increased predation, extreme terrain) and flying becomes the only viable way to survive.
- Gradual Changes: The evolution would not be instantaneous. Over vast stretches of time, tiny variations giving the slightest advantage in terms of air mobility (like slightly longer arms, lighter bones etc.) would be favored.
- Reproductive Advantage: Individuals with these early, proto-wing structures would need to have a significant reproductive advantage over those without.
Conclusion
Essentially, the physical and physiological changes necessary for human flight are extreme, and the required selective pressures are absent. While we can imagine humans flying, our evolutionary trajectory does not point in that direction. The reference indicates that it is "virtually impossible," further supporting this conclusion.
