Homing Pigeons Navigate via Simple Averaging, Challenging Complex Cognition Assumptions
A study published in eLife suggests homing pigeons use a simple strategy called route averaging when navigating in groups. The research challenges the assumption that complex cognitive processes are necessary for navigational improvements in social animals.
Commenters largely agree with the study's findings, but some question whether the results fully support the concept of cumulative cultural evolution. Others argue that the simplicity of the averaging strategy might not account for all navigational complexities. One commenter noted that 'the wisdom of crowds improving routes 'for free' without placing additional cognitive load on the birds' raises broader questions about social learning mechanisms.
The community consensus leans toward the study's implications for understanding social learning in animals. However, there are notable fault lines, with some suggesting the findings may not fully explain navigational complexities or support broader theories like cumulative cultural evolution.
Key Points
