A study published by El País reveals that certain animal species, including chimpanzees, monkeys and cockroaches, exhibit collective behaviors that can be interpreted as votes for choosing among options.
According to the article available at https://elpais.com/ciencia/2-than-11-10/chimpances-monos-y-cucarachas-los-animales-tambien-votan-y-sus-elecciones-pueden-ser-manipuladas.html, researchers have observed that these animals use social communication mechanisms to express group preferences regarding resources or shared decisions.
Social behaviors and collective choices
For example, chimpanzees have demonstrated a capacity to select between different types of food in groups, showing a decision pattern similar to human voting. In controlled experiments, individuals position themselves in front of distinct options, and their collective behavior reflects a form of consensus.
In the case of cockroaches, recent studies indicate that these arthropods can show group preferences when presented with a choice between two environments or food sources, suggesting the existence of simple yet effective social mechanisms.
Communication mechanisms
Scientists have identified that these animals use visual, tactile, and chemical signals to communicate about their preferences. For example, among monkeys, certain body movements and sounds allow members of the group to express support or rejection toward shared decisions.
No direct voting mechanism has been established as in humans, but collective choices emerge through repetitive behavioral patterns observed during group interactions.
Potential manipulation
The article states that these behaviors can be influenced by external factors such as the physical environment or the presence of specific stimuli. For example, if an environment offers more resources, animals tend to concentrate there, which may be interpreted as expanded social preference.
It has not been confirmed that these mechanisms are used for strategic decision-making in complex contexts, but empirical evidence does exist showing that species exhibit collective behaviors reflecting group decisions.
