Researchers at the Champalimaud Centre for the Unknown have discovered that fruit flies freeze as a social cue of danger, but also resume movement when others start moving again, signaling safety. Group size plays a crucial role in this behavior, with smaller groups freezing less and larger groups showing a more complex response pattern.
Researchers found that when flying alone, individual fruit flies freeze as a response to an imminent threat, but this behaviour changes in the presence of others. When other flies begin to move after the threat has passed, it signals safety and causes the freezing fly to exit its frozen state.
Researchers found that mother bats adjust their vocalizations to provide positive feedback to their pups during vocal practice, while male bats transmit the social group's vocal signature. This complex parent-offspring communication may be a key feature of bat language development.
Researchers found that primates have evolved larger, more variable larynges with faster adaptation rates compared to carnivores. This difference is linked to vocal communication systems, suggesting a key role for the larynx in primate behavior.
The study found that primate larynges are on average 38% larger than those of carnivorans for a given body length, indicating greater flexibility in evolution. The rate of larynx evolution is also faster in primates, with more variation in larynx size relative to body size.
