A study by scientists from the University of Cambridge has revealed how cooperative behaviour between insect family members changes how rapidly body size evolves – with the speed of evolution increasing when individual animals help one another.
New research suggests that cooperative breeding makes mammal species such as meerkats better suited to dry, harsh climates.
Largest quantitative study of howling, and first to use machine learning, defines different howl types and finds that wolves use these types more or less depending on their species, resembling a howling dialect. Researchers say findings could help conservation efforts and shed light on the earliest evolution of our own use of language.
An online experiment reveals that the overall level of cooperation in a group almost doubles when the previous actions of all its members are rendered transparent. When all social connections within the group are also made transparent, the most cooperative band together to form their own community – ostracizing the less cooperative.
New research shows that male jays are able to disengage from their own current desires to feed their female partner food that she wants.
