It is well-known that humans have significantly transformed ecosystems since their adoption of agriculture. However, in a deeper past, prehistoric hunter-gatherers may already have altered and modified their niche in ways that had major impacts on ecosystems.

Correctly interpreting the patterns of fire evidence in the archaeological record will illuminate the origin of human fire use.

This NWO-funded research programme focuses on the assumptions and methodology of the writing of history of science. History of science is in many respects a flourishing discipline: it currently yields an impressive volume of studies. Systematic reflection about the ways in which history of science may…

Despite the field’s general agreement that pyrotechnology had a significant impact on the cultural evolution of humankind, our understanding of the origins and development of fire use and its role in humankind’s cultural evolution is very limited, blurred by strong disagreements over its chronology…

On 25 May, Roxane de Massol de Rebetz defended the thesis 'Beyond the dichotomy between migrant smuggling and human trafficking: a Belgian case study on the governance of migrants in transit'. The doctoral research was supervised by Maartje van der Woude, Joanne van der Leun and Masja van Meeteren.

The Faculty of Science is located at the Leiden Bio Science Park. It was founded more than two centuries ago and currently, more than 8000 people are working and studying at the eight institutes.

Making an impact by creating solutions for the challenges of the future. That’s what we do through our education and research in biodiversity and sustainability, artificial intelligence, complex networks, new medicines, quantum technology, and galaxies.

Historiography of science is in its current self-image a non-evaluative discipline. Its main goal is to understand past processes of knowledge formation on their own terms. In the last few decades this approach has greatly improved our understanding of the phenomenon of science. Yet, something strange…

To what extent are, can, and should, human trafficking and human smuggling be(ing) seen as interlinked phenomena? What are the consequences of seeing the phenomena as either distinct or interlinked for the way in which migrants crossing intra-Schengen borders are treated.

Nature and History, Towards a Hermeneutic Philospohy of Historiography of Science

The central question in this book is whether there is a human right to family unification.

Environmental humility is integral to addressing the climate crisis, but humility can also lead to political domination. How can humans relate to nature more humbly without risking domination?
