An international team, led by Dr. Sabrina Simon (Wageningen University & Research) and Dr. Hojun Song (Texas A&M), succeeded in tracing the evolution of acoustic communication in the insect family of crickets and grasshoppers (Orthoptera). The results show that crickets were the first species to communicate, approximately 300 million years ago. The results are also significant because it was the first time this analysis has been done on such a large scale. The publication by Dr. Simon et al. appeared in the prominent scientific journal Nature Communications today.
