Is music a supernormal stimulus?

Fragment of an interview of Richard Dawkins with Steven Pinker for the documentary series The Genius of Charles Darwin (UK Channel 4 Television, 2008). Pinker explains again why music is not an adaptation, but should be seen as a kind of 'supernormal stimulus' - adding the phrase people in music hate this theory....

Is music a supernormal stimulus?

One hour of raw footage (!) of an interview of Richard Dawkins with Steven Pinker for "The Genius of Charles Darwin" (UK Channel 4 Television, 2008). Pinker explains again why music is not an adaptation but should be seen as a kind of 'supernormal stimulus' - adding the phrase "people in music hate this theory...".

Is music cognition?

Many studies on the evolution of music concern the question of what defines music. Can birdsong, the song structure of humpback whales, a Thai elephant orchestra, or the interlocking duets of Gibbons be considered music?

The answer is of course a simple ‘yes’. A definition of music can easily be stretched to include all types of sound, noises and even plain silence. As such it makes the discussion of what is and what is not music one of the most noticeable pitfalls in the study of music and evolution. An alternative is to separate between the notions of ‘music’ and ‘musicality’, with musicality as a natural, spontaneously developing trait based on and constrained by our cognitive system, and music as a social and cultural construct based on that very musicality.

Of course this definition of musicality is still too general to be useful. The challenge is to define what precisely makes up this trait we call musicality. What are the cognitive mechanisms that are essential to perceive, make and appreciate music? Only when we have identified these fundamental mechanisms are we in a position to see how these might have evolved. In other words, the study of the evolution of music cognition is conditional on a characterization of the basic mechanisms that make up musicality.

Furthermore, it is important to separate between the biological (or genetic) and cognitive (or functional) aspects that might contribute to musicality. While it is common to assume that there is a mapping between specific genotypes and specific cognitive traits, more and more studies show that genetically distantly related species can show similar cognitive skills; skills that more genetically closely related species fail to show. For example, more and more studies show that humans and certain bird species share their musicality up to a certain level, whereas humans and chimpanzees do not.

Does natural selection play a role in cultural change?

Natural selection expresses the idea that organisms (i.e. their genes) vary and that variability has consequences. Some variants are unfit and go extinct, others adapt and do well. This process, repeated over millions of years, has given us the variety of life on earth.

Many authors have played with the idea how to combine these insights from evolutionary biology to changes in culture, the notion of ‘memes’ being one of them. Richard Dawkins proposed that human culture is composed of a multitude of particulate units, memes, which are analogous to the genes of biological transmission. These cultural replicators are transmitted by imitation between members of a community and are subject to mutational-evolutionary pressures over time.

Recently researchers at Imperial College London started yet another attempt to try to show if, and how, natural selection might play a role in music. They are currently running an online experiment hoping to find support for this idea:

Why do we have music? (On music vs musicality)

Looking back on it, a returning question in this blog turns out to be: Why do we have music? And what is the point of studying it scientificly?

While it became quite popular to address such questions from an evolutionary perspective, there is still little support for the idea that music is an adaptation, that it makes you live longer, or that it makes one sexually more attractive. In fact, it made Steven Pinker position music as, at most, a byproduct of language:
As far as biological cause and effect are concerned, music is useless … music is quite different from language … it is a technology, not an adaptation (Pinker, 1997)
This statement —and the reference to music as ‘auditory cheesecake'— did not, as you can imagine, increase his popularity among music lovers. Nevertheless, he succeeded well in starting up a discussion under music scholars and cognitive scientists on why we have music and why it could be relevant for cognitive science to study music (e.g., Ashley et al, 2006; Zatorre, 2005).

In that respect, the archaeologist Steven Mithen did something you might have expected from a music scholar or cognitive scientist. In his book The Singing Neantherthals he presents a compelling story in support of the shared evolutionary origins of music and language. As the book title suggests, Mithen is particularly concerned with the Neanderthals, presenting them as intelligent and highly emotional individuals who communicated with a particularly musical version of Hmmmmm. (‘Hmmmm’ being Mithen's proposal for a musilanguage that might have preceded language and music).

In turn, Mithen’s book generated quite some discussion as well. In part because of the (impossible) question on what defines music, or, to be more precise, the important distinction between musicality and music. In a recent paper Mithen makes himself more clear:
The distinction I should have made explicit was between a ‘natural biologically based musicality’ and music as a culturally constructed phenomenon which builds upon that biological basis. So the musical ‘m’ in Hmmmmm ought to stand for the former — which had seemed quite obvious to me already — while the latter developed after Hmmmmm had bifurcated into music and language. Although I appreciate that the following have a culturally learnt component, I would describe bird song, whale song, primate vocalizations and baby babble as possessing musicality rather than being music.
