Does UVA (long-wave ultraviolet) light behave more like visible light than higher-ene

Does UVA (long-wave ultraviolet) light behave more like visible light than higher-energy ultraviolet light?

It seems to just be an evolutionary accident. UVA light scatters far more easily than visible light (especially in water, so our aquatic ancestors had no need to evolve UVA light receptors). Furthermore, UVA light doesn't stimulate electrons in the way that UVB and UVC light do.
