Animal cumulative culture through changing environments.

Area of Science:

• Behavioral Ecology
• Evolutionary Biology
• Animal Cognition

Background:

• Human ecological success is linked to cumulative cultural evolution (CCE).
• Empirical evidence for CCE in animals is growing but remains inconclusive.
• Existing experimental designs may not adequately capture conditions necessary for animal CCE.

Purpose of the Study:

• To identify limitations in current experimental approaches for detecting animal CCE.
• To propose novel methodologies for studying CCE in non-human animals.
• To introduce a generalizable experimental paradigm for testing CCE.

Main Methods:

• Critically reviewed existing experimental paradigms for animal CCE.
• Developed new experimental methodologies tailored to detect CCE.
• Utilized Temnothorax ants as a model system to illustrate the proposed methods.

Main Results:

• Identified key experimental limitations hindering the conclusive demonstration of animal CCE.
• Proposed and illustrated novel methods for detecting CCE in animal populations.
• Demonstrated the applicability of a new experimental paradigm using Temnothorax ants.

Conclusions:

• New experimental approaches are essential for conclusively demonstrating CCE in animals.
• The proposed methodologies and paradigm offer a path forward for studying animal CCE.
• Temnothorax ants serve as a valuable model for understanding the evolution of CCE.
