Fossils Reveal When Animals Started Making Noise

New research into the early noise making in the Animal Kingdom points to insects, Author Michael Habib tells us that animal noise making began during the Cambrian period between 541 and 485.4 million years ago, but was restricted to "the skittering of arthropod feet across sand or the faint grinding of a cephalopod breaking a shell" while "the terrestrial realm remained essentially silent. 200 million years would pass before insects started making noise in open air: the katydid, 250 million years ago. He also points to the evolution of the larynx 300 million years ago, without specifically naming the lungfish, as we have cited researchers naming in this chapter (see Midgley and Allen 2002 and Fitch 2010 on page 29 of this chapter for sources).
