Wolf
The wolf's adaptability stands as one of evolution's more impressive achievements. Canis lupus historically ranged across the entire Northern Hemisphere, thriving in environments from Arctic tundra to Middle Eastern deserts. Their social structure permits rapid adjustment to varying prey densities, with pack sizes fluctuating according to available resources.
Physiological adaptations include fur density variations across subspecies, metabolic adjustments for feast-and-famine feeding patterns, and remarkable thermoregulation that permits activity in temperatures ranging from -40 to 40 degrees Celsius. The wolf's genetic contribution to domestic dogs—some 400 recognised breeds—further demonstrates extraordinary phenotypic plasticity. Few mammals have demonstrated such capacity for environmental accommodation.
Time
Time's adaptability presents a philosophical paradox: it adapts to nothing because it encompasses everything. Whether in the vacuum of intergalactic space or the crushing pressure of a neutron star's core, time proceeds with identical indifference. It requires no thermoregulation, no prey base, no social structure.
Einstein's relativity revealed that time does possess a form of flexibility—dilating near massive objects and at high velocities. Yet this relativistic behaviour represents not adaptation but fundamental physical property. Time does not adjust to circumstances; rather, circumstances exist within time's framework. The wolf adapts to survive; time simply is, regardless of what exists within it.
