Existing theories seem incomplete, so right here’s any other one. I suppose music is a side impact of the evolution of self-awareness and love.
Music does have quite a few features we accomplice with sexual competition. It’s (historically speaking) an honest display of abilities, it exploits supernormal stimuli, and it’s attractive. But if those matters have been enough for its evolution, it’d be tremendous in other species. Instead, the song appears to be nearly specific to people.
In maximum species, presentations are absolutely flamboyant exhibitions of man or woman prowess. Every peacock targets to have the largest, flashiest tail; there is none of the complexity or variety we accomplice with a track. Guppies appreciate novel hues in their associates, but they do now not evolve growing complexity.
Closer to human music are the songs of pure birds. While nobody might deny that most bird song is some type of sexual competitive signal, music complexity is not continuously related to sexual selection at all. And quite complicated and ranging birdsongs, such as those of the track sparrow, may be generated using easy algorithms. Nothing in the animal world even remotely methods the complexity and diversity of human tune.
It’s also frequently counseled that music contributes to organization bonding, which will be nice for a species like ours, wherein inter-tribal opposition may additionally have encouraged evolution. And seeing that human beings are unusual in that sense, it additionally allows giving an explanation for the distinctiveness of song. There are masses of evidence that song does play this role. However, group choice is usually a weak pressure, while the tune is a luxurious characteristic; it is difficult to see how the previous could be enough to account for the latter.
Perhaps track advanced as a sexually decided on a characteristic which becomes co-opted beneath organization selection. But perhaps there may be a bigger hollow in our thinking.
What neither concept appears to explain in any respect is why tune is, nicely, musical. Why have to group or pair bonding contain the type of fractal complexity, chronic novelty, and specificity of flavor that units track aside from not unusual birdsong?
Hofstadter in Gödel, Escher, Bach: An Eternal Golden Braid argues that focus is a recursive computational technique. Self-awareness, in addition, implies that the aware thoughts incorporate a model or representation of the self.
What is that this model? Why represent your self, when you may absolutely be your self? The solution, possibly, is that maximum of the mind isn’t conscious, nor even on hand to focus. So to have insight into your very own behavior, you mentally version yourself in plenty the equal way you version different people.
You see the hassle. Modeling other conscious, self-conscious minds requires an inner awareness, self-aware mind for each thought you version. Each of those fashions must in flip have its personal models of other aware, self-conscious minds … and so forth to infinity.
Our brains do no longer have countless potential. So what do we do while we stumble upon an infinitely recursive system? Curl up in despair? No! We approximate. We gaze as deeply as we are able to into the fractal, stretching the limits of our cognitive potential. And then we well knew and accept the one’s limits. We wonder at the tininess of the self within the wondrous grandiosity of the universe. We are overcome with religious joy.
In different words, we congratulate ourselves on our willingness to stand the limits of our comprehension. Why does this make us sense suitable? It’s adaptive.
We are a surprisingly social species. Many researchers consider that human cognition became, for lots of our evolutionary records, stuck in a positive comments cycle of social selection. That is, those of our ancestors who ought to higher understand and expect others had more evolutionary fitness, which made each succeeding technology tougher to understand and expect that its mother and father.
So: it is fine to revel in peering into the depths of thrilling fractals, due to the fact that stretching of cognitive ability is exactly what is required to version minds better than our peers. And the track is often thrilling fractals.
I want to take matters a little similar. Let’s communicate approximately love.
We’re no longer just social. Lots of animals are social, and most of them are utter jerks. Humans, together with many birds and a few mammals, have strangely sturdy, lasting cooperative relationships among unrelated adults. We have love and believe.
