Three Candidate Mechanisms for One Voice Pitch Locus

Assembles hypotheses 1, 2 and 3 side by side — adrenal steroid signalling, shared elastin/collagen tissue properties, and direct action on the vocalis — and makes the point that all three are compatible with every number the paper reports. Competing-and-unresolved is the finding; students should be able to hold three live options without collapsing to one.

Questions this Concept answers

  • Why can all three of the proposed mechanisms remain live at the same time?
