Behavioral Complexity Emerges as a Mosaic, Not a Package
The development of complex human behaviors was not a singular event but a spatially and temporally varied process across different regions.
Journal of Human Evolution · 2023
Key Findings
- 01The concept of a discrete 'modernity package' for behavioral complexity is obsolete.
- 02Behavioral complexity emerged asynchronously across different regions of Africa, forming a mosaic pattern.
- 03The development is better explained by variable manifestation of cognitive capacities influenced by demographic factors (population structure, size, connectivity) rather than direct brain changes.
- 04Periods of stasis and lack of cumulative development challenge strictly gradualistic models.
Application
Design takeaway
Designers should recognize that innovation and complexity are not linear or uniform, and successful design interventions will likely need to be tailored to specific socio-cultural and demographic contexts.
How to apply
When developing new products or systems, consider how different user groups in varied locations might adopt and adapt them, and how connectivity between these groups might influence the diffusion of innovation.
Project actions
- 01When researching user needs, consider the diversity of your target audience and their unique contexts.
- 02Explore how different cultural factors might influence the adoption of your design.
- 03Don't assume a single, universal solution will work for everyone.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Comprehensive review of extensive archaeological data.
- +Challenges established, potentially oversimplified models of human evolution.
Limitations
Archaeological evidence is incomplete and open to interpretation. The exact mechanisms linking population dynamics to behavioral complexity are complex and not fully understood.
Reliability & validity
The reliability of the findings depends on the consistency of archaeological interpretation and the robustness of the synthesized data. Validity is supported by the challenge to existing paradigms and the proposed parsimonious explanation.
Think critically
If behavioral complexity is a mosaic, how can designers effectively create solutions that are both innovative and adaptable to diverse, non-uniform user bases?
Design Principles
"Embrace the mosaic: Design solutions should acknowledge and leverage the inherent variability and interconnectedness of human behavior and technological adoption."
Understanding the non-linear, mosaic nature of innovation is crucial for designers and engineers. It suggests that solutions and advancements often arise from diverse, interconnected contexts rather than a universal blueprint, influencing how we approach problem-solving and product development.
What This Means for Your Design
Think of how different countries or cities have different trends and technologies at different times. Human behavior developed in a similar way – not all at once everywhere, but in different places at different times, like a patchwork quilt.

Paragraph starter
The research by Scerri and Will (2023) highlights that behavioral complexity in humans did not emerge as a unified 'package' but rather as a mosaic, with innovations appearing asynchronously across different regions of Africa. This suggests that design projects should move beyond assuming a universal user or adoption pattern, instead focusing on understanding the specific socio-cultural and demographic contexts that influence how users interact with and integrate new technologies.

- How strong is the evidence?
- Evidence strength is rated Strong effect, based on a 2023 journal from Journal of Human Evolution.
- What should I do differently in my next project?
- When developing new products or systems, consider how different user groups in varied locations might adopt and adapt them, and how connectivity between these groups might influence the diffusion of innovation.
- What are the limitations?
- The interpretation of archaeological data can be subject to ongoing discovery and revision. The precise causal links between demographic factors and behavioral complexity require further detailed investigation.
- Is there evidence that behavioral complexity affects design outcomes?
- The study found that complex human behaviors developed in a fragmented, uneven way across Africa, not as a single package or a smooth, continent-wide progression, and was driven by population dynamics and cognitive flexibility rather than simple brain evolution.
