Neurodiversity and evolutionary trajectories

Evolutionary analysis of human cognitive and behavioural variability

Neurodiversity and Evolutionary Trajectories

Lego-brain-neurodiversity — One brain, many pieces: the LEGO® model as a structural metaphor for human neurodiversity.

The Neurodiversity and Evolutionary Trajectories project forms part of the HUMAN – Human Understanding, Mind and Anthropogenesis Initiative of the Centro Rausenbach de Análisis e Investigación (CRAI). Its objective is to analyse human cognitive and behavioural diversity from an evolutionary, integrative, and non-pathologising perspective, with particular attention to profiles associated with ADHD, ASD, and other expressions of neurodiversity.

The project is based on the premise that neurocognitive variability does not constitute a deviation from human development, but rather an expected consequence of differentiated evolutionary trajectories shaped by environmental pressures, cultural contexts, and processes of neural plasticity. Within this framework, the biological, cognitive, and cultural foundations that explain the historical persistence and functionality of these profiles are investigated.

Hypothesis

Human neurodiversity reflects the coexistence of multiple cognitive configurations that emerged as functional adaptations within diverse evolutionary contexts. The contemporary expression of profiles such as ADHD or ASD may be understood, at least in part, as the result of a mismatch between evolutionarily conserved neurocognitive configurations and the demands of the modern environment, rather than as an intrinsic dysfunction of the individual.

Vision

To contribute to an evolutionarily informed understanding of human neurodiversity by integrating neurobiological, psychological, and anthropological evidence in order to redefine current interpretative frameworks and promote educational, social, and health approaches that are better aligned with the cognitive diversity of our species.

From Evolution to Cognitive Profiles

The project develops conceptual and comparative models that link empirical observations to specific evolutionary periods and their associated cognitive configurations. Through this approach, patterns of attention, perception, emotional regulation, and social behaviour are analysed as expressions of historically adaptive strategies, reinterpreted within the contemporary context.

The scientific gap

The objectives of the project address several key gaps in current research:

Neurodiversity is often addressed within ahistorical and reductionist clinical frameworks.

Profiles associated with ADHD and ASD are rarely analysed within their evolutionary context.

The interaction between biology, culture, and environment in shaping cognitive configurations remains insufficiently integrated.

There remains a disconnect between neurobiological data and high-level explanatory models.

Methodological approach

The project adopts an interdisciplinary approach that enables the interpretation of neurodiversity as an emergent phenomenon of complex biocultural systems, beyond rigid diagnostic categories. This approach combines:

cognitive and developmental neuroscience

evolutionary and behavioural psychology

biological and cultural anthropology

comparative analysis of evolutionary trajectories

conceptual modelling and integrative synthesis

Scientific and social relevance

From a scientific perspective, the project contributes to the development of integrative theoretical frameworks on the human mind and its diversity. At a societal level, it provides a conceptual foundation for improving public understanding of neurodiversity and for informing the design of educational, social, and health strategies aimed at enhancing the quality of life of neurodivergent individuals and communities, without presupposing specific clinical interventions. In addition to its scientific contribution, the project includes dissemination and knowledge-transfer activities through the development of guides and resources for teachers, families, and other non-specialist audiences, with the aim of fostering a more informed and nuanced social understanding of neurodiversity.

Expected results

The Neurodiversity and Evolutionary Trajectories project will generate an integrative body of knowledge enabling the reinterpretation of human cognitive and behavioural variability within an evolutionary, biocultural, and non-pathologising framework. Through the development of conceptual and comparative models, the project is expected to clarify the relationship between specific cognitive configurations, evolutionary contexts, and contemporary environmental demands. These outcomes will provide a robust theoretical foundation for enhancing both scientific and social understanding of neurodiversity, as well as for informing future applications in education, social policy, and health, without presupposing specific clinical interventions. The project will generate:

evolutionary explanatory models of human cognitive variability

non-pathologising theoretical frameworks for ADHD, ASD, and other neurodivergent profiles

conceptual criteria for reinterpreting adaptive difficulties within modern contexts

scientific foundations for future applications in education, health, and social policy

Team and collaborations

The project is developed within the framework of the CRAI’s HUMAN Initiative and is open to national and international collaborations in neuroscience, anthropology, psychology, cognitive science, and related disciplines.

Collaboration

The CRAI invites researchers, academic institutions, and organisations interested in neurodiversity from an evolutionary perspective to establish contact in order to explore scientific collaborations, joint projects, and shared conceptual developments.
