Resonant Biology is the scientific study of how flora and fauna on Xylos have adapted to the planet's background sonic radiation. Unlike Earth-based life, which relies primarily on electromagnetic radiation (light), Xylosian life utilizes acoustic energy generated by the Whispering Skies.
Key examples of this adaptation include the Whisper-Vines, which possess microscopic cilia capable of converting sound waves into chemical energy (glucose). Similarly, Echo-Fauna have developed skeletal structures that act as natural tuning forks, allowing them to sense changes in air pressure and "hear" color.
This field was pioneered by the Aethelgard Institute. Their research suggests that these organisms are not merely reacting to sound but are biologically synced to the resonant frequency of Chronosite. This connection makes local wildlife extremely aggressive towards mining machinery, which disrupts their natural frequencies.
Attempts to transplant Xylosian plants to other planets have failed, as they wither and die without the constant hum of their homeworld.
