I hear you guys, the last few comments here, and appreciate your perspective.
But allow me to illustrate something about the human capacity for language that may give a better perspective to my comments.
Code is code. The formal definition is simply the mapping of probability space A to probability space B. That’s what every code has in common. No exceptions. So this is not a matter of “understanding” a non human language. It’s a matter of “mapping” one language to another, and then being able to understand it to the degree that is possible between species.
SETI is NOT looking for extraterrestrial life. SETI is looking for a codified signal. For they know that every codified signal must have an accompanying author intelligent enough to codify their thoughts. Human SETI may not be capable of understanding ET message. But SETI can map the ET code, and slowly decipher the message for human understanding, to the degree that humans can.
Same with DNA. We map that code. But it takes a long long time to decipher what it all actually means.
There is a marine scientist (sorry no links) who video tapes dolphin behavior and records the sounds they make with each accompanying action. The scientist blasts the sound upon the bottom of an aluminum plate covered with sand. As the sound vibrates the aluminum plate, the sand forms a specific symbol from the vibration. They record the symbols created for each sound, and form an alphabet from the symbols. It’s no different than the symbol “R” meaning something beyond what it looks like.
Different dolphins make the same utterance for the same actions. They each create the same symbols in the sand. They are slightly different, but not any more so than you and I comparing our handwriting differences. The symbols are the same, though not identical.
The symbols are fed into computer which associates each with the dolphin sounds of each action. The symbol imbibed computer plays the recording of dolphin sounds, and the dolphins respond the same as if receiving instructions from another dolphin.
“Food over here” means the same thing whether spoken in English, Chinese, or Dolphin symbology. And from this primitive communication protocol, we can speak Dolphin-ese.
Humans have deciphered numerous messages from the Figure 8 waggle dance of the bumble bee. The messages from the bee determine the direction of food, directions to the food, alternative directions, and even weather conditions denoting wind drift encountered along the way. It’s not just a predator warning cry. It’s real messages that provide instructions to other bees, and now humans too.
Submarines broadcast Whale song. And I’ve seen the same done with Wolves.
If it’s a code, it will meet Purlwitz, Burks and Waterman’s formal definition described above. And when those protocols are met, then humans can map it to any other language they choose. Understanding it is a completely different matter.
