>>11801578Yes, the article does also mention the possibility Neanderthals were capable of song/singing communication too. So if Homo-Sapiens and Neanderthals did communicate with each other verbally it may have been through song. But this is purely conjecture and goes into the debate of wether or not song itself can be considered a language.
I'll admit this may indeed be a possibility. However then conversation must go into how well did our two species understand each other's song and if the crossbreed offspring were capable of learning both species song/language, favored one species more or only had remedial understanding of both but was able to continue mating into human populations regardless of that deficiency.
>>11801664I'm aware that various species are capable of cross breeding with each other for fertile offspring. But do you have links to any research that shows those two species were capable of learning each other's languages/communications fully on top of cross breeding? That's the big issue here that is hard to figure out since that's the set of features humans have that others don't.
For instance there is research of experimental mixed colony of Asian and European bees that can learn each other's dance. Although it is still controversial because researchers debate if bee waggle dance can be considered a language, if bee species actually have different waggle dance dialects and if the two species in question actually can properly decode each other. Even if two bee species can properly learn each other's language. They do not seem to yield hybrid offspring in general let alone hybrid offspring that is fertile. Humans are alone with this set of features.
