Teoría de que música cumple función de verificación de filiación. Transcript: Speaker 1 I was driving into work one day, and song came on the radio that I hadn’t heard since high school, and I wish I could remember what the song was. I don’t. But I immediately started singing along with the song, and it struck me. I was able to, even though I hadn’t heard the song in decades, is that right? It was close to right. I was able to sing exactly in sync. I had the lyrics exactly right, all the changes in tempo, and it really struck. And my memory is not that great, and I’m not a musician. So it really struck me, how am I able to, you know, what cognitive abilities must I have and all of us have that a song that I haven’t heard in years and years, it wasn’t even a favorite song. It’s just one that was popular when I was in high school. How can I sing with such precision and timing and the lyrics? That really told me that we have specialized memory for music. It suggests to me there’s really strong hypothesis here that we have a specialized musical memory because if this had been a speech, no way, but I’ve been able to do that, even if it was My own speech. So I began thinking, what might have been the selection pressures? Why might it have been adaptive for us to have a specialized memory for music if indeed we do? And so I began thinking about that on the drive-in and thinking that music is typically performed in groups. Essentially that’s what I was doing is I was singing along with the song and essentially performing with the other musicians. And why might that have been somehow reproductively beneficial to our ancestors if indeed it was? And it just kind of hit me that this might be some kind of signal of what I call now a coalitional quality or the fact that we are a group and that we might be signaling that to other groups. And I thought that was a really interesting idea. (Time 0:03:39)

Specialized Musical Memory and Its Evolutionary Significance Humans may have a specialized memory for music, evidenced by the ability to accurately sing along to a song with precision and timing. This suggests a strong hypothesis for the existence of specialized musical memory. The evolutionary advantage of such a memory could be linked to the adaptive pressure for humans to have a specialized memory for music, likely due to the reproductive benefits of music being typically performed in groups. The act of performing music in groups may have served as a signal of coalitional quality, indicating the cohesive nature of a group to other groups.
