Animal communication rhythms frequently share a common tempo range, study suggests
Diverse species produce rhythmic signals between 30 and 240 beats per minute, Scientific American reports.
The short version
- A study of animal communication found rhythmic signals across diverse species frequently fall between 30 and 240 beats per minute.[Scientific American]
- The analysis was prompted by observations in Thailand of crickets chirping at roughly 145 beats per minute alongside synchronized fireflies.[Scientific American]
- A computer model indicated simple neural circuits respond best to signals within this tempo span.[Scientific American]
- Researchers note neural processing is merely one candidate driver, alongside bodily rhythms like breathing or movement.[Scientific American]
Key facts
- Observations in Thailand revealed crickets and fireflies both signaled at nearly 2.4 hertz, or approximately 145 beats per minute.[Scientific American]
- A broad survey of communication studies indicated signals across diverse species repeatedly fell between 0.5 and 4 hertz.[Scientific American]
- An examination of 124 wildlife sound recordings identified 50 species whose rhythmic signals clustered in that range, peaking near 180 beats per minute.[Scientific American]
- A computational model showed simple neural circuits tuned to 120 beats per minute responded most effectively to matching tempos.[Scientific American]
What remains uncertain
- Whether neural processing drives these preferred tempos remains unconfirmed, as bodily rhythms like respiration and movement may also set the pace.[Scientific American]
