| Why evolution by natural selection didn't make use of RF? |
| (1/16) > >> |
| RoGeorge:
Life evolved many ways of sensing and signaling, from chemical, to sound, to light in the IR to UV spectrum, but no RF. How so? |
| Gyro:
Derrr, because there is no known way of biologically generating RF and there was nothing to listen to on the radio while they were evolving? |
| Kim Christensen:
Also, there was no need. Sound and light work "good enough" to eat, excrete, breed, avoid predators, etc... |
| DavidAlfa:
Because probably there's no chemical reaction capable of generating low frequency RF. Edit: Damn, Gyro had already said exactly this :D |
| TimFox:
Natural selection is just that: selecting which of already available options leads to success in breeding future progeny with that option selected. Feathers evolved as a useful insulation mechanism before they were used in flight. |
