call across all

Communication has roots too.

James Gillooly:

“Our results indicate that, for all species, basic features of acoustic communication are primarily controlled by individual metabolism, which in turn varies predictably with body size and temperature.

So, when the calls are adjusted for an animal’s size and temperature, they even sound alike.”

Commonalities, yes, in the sounds of hundreds of species of insects, birds, fish, frogs, lizards and mammals.
