The HARVEST project explores the dietary choices that our hominin ancestors and relatives made, by recovering information on what they consumed, and how factors like environmental variation, intrinsic biology, and development of food processing technologies could have influenced their decisions.

This multidisciplinary minor addresses the fascinating question how we, modern humans, got to be the way we are. Who were our ancestors? How does our morphology, genetic makeup, brain and behaviour relate to that of other species? How does our evolutionary past affect our susceptibility to diseases?…

Evolutionary and ecological interactions affect species on genetic and phenotypic levels. This theme aims to understand these processes at multiple levels: from molecules to genomes to populations and to communities. Our research focuses on evolutionary responses to anthropogenic change, the role of…

Microbial Sciences' contribution to the Biodiversity & Evolution research theme focuses on understanding how bacteria sense and respond to their environment, and how bacterial diversity and evolution is influenced by cooperative and antagonistic interactions taking place between microbes.

Why do plants produces always produced so many slightly differing metabolites within a particular chemical class?

In this course, you will develop an understanding of evolutionary processes and their formative power. You will see how evolution has shaped biodiversity, and continuously influences our daily life.

One of the main research focuses of the Hortus botanicus Leiden is to study how the current biodiversity we see today, has originated, changed, and developed over time. The Hortus wants to study the relationship between species in specific focal taxa and see how they have diverged over time.

The Leiden Human Evolution Collective (LHEC) is a network of researchers from Leiden University, LUMC, and Naturalis with an interest in human evolution. The collective brings together existing expertise in Leiden to foster interdisciplinary collaboration in research, teaching, and public outreach.

Studies in Human Evolution is a series of the Faculty of Archaeology, Leiden University and The Max Planck Institute for Evolutionary Anthropology, Leipzig.

Animal Sciences’ contributions to the Biodiversity & Evolution research theme include evo-devo research, the evolution of cognitive and behavioural traits, and the evolutionary mechanisms of stress adaptation. This research involves both indoor and outdoor studies.

Plant Sciences' contribution to the Biodiversity & Evolution research theme is to understand what are the key drivers of plant biodiversity during evolution with a focus on plant life history and resilience traits and develop tools to restore and maintain plant biodiversity.

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…

The Great Rift Valley in Africa is a real treasure trove for discovering early human fossils. The fossils found in this part of Africa have determined our view of human evolution. But was the Great Rift Valley really the place where evolution took place or just a place where fossils are well preserved…

How has early development in R. ocellatus been modified as a result of its parasitic embryonic lifestyle?

Galaxies in the local Universe fall into two main categories of spirals and ellipticals. In this Thesis, we explore the structural evolution of galaxies into this bimodal distribution.

Balsaminaceae is a diverse plant family characterized by a huge floral morphological diversity.

Negotiation can only really be an alternative to warfare, if the parties agree on a framework of rules and procedures. And if the confidence of the partners may increase in another. But negotiations continue to wage war by peaceful means.

The soil-dwelling, filamentous bacteria of the genus Streptomyces are renowned for their production of useful secondary metabolites including antibiotics. The work described in this thesis provides new insights on the role and regulation of antibiotic production and resistance in these bacteria.

In my research, I used a comparative wood anatomical approach to address wood evolution of the (largely) tropical flowering plant families Apocynaceae and Sapotaceae.

Sustainable energy from wind and solar is most readily available near the sea.

The thesis is about the study of shell evolution of the Hydrocenidae of the genus Georissa. This thesis started with a general overview on the evolutionary process of animals due to ecological changes.

Electrocatalysis allows for storing electricity or converting it into chemical bonds, producing chemical building blocks and fuels using renewable resources.

We have examined sequences from the ligand-binding domain of the nicotinic acetyl choline receptor (nAChR) in 148 vertebrate species. We are in interested in this receptor because the α-neurotoxins of many venomous snakes binds to this receptor in its location at the neuromuscular junction in all ve…

A study by a Leiden-Wageningen group shows that present-day humans are biologically poorly equipped to deal with the toxins they are regularly exposed to in smoky environments: compared to earlier hominins, we modern humans are probably even worse off. The study appeared in Molecular Biology and Evolution.…

Are traces of fire use detectable in ancient hominin genomes?

Research into the evolutionary backgrounds of our diets can help us make the right choices in diet, health and lifestyle.

Bicarbonate buffer is largely found in nature due to its ability to regulate pH variations around neutral values. As the pH changes, so does the speciation of the buffer.

This dissertation examines the European Union’s response to the growing problem of disinformation. It uses this case to critically analyse how societies interpret and manage information challenges such as ‘fake news’ and propaganda.

Has there been continuity or change in US counterterrorism policy since 9/11? What factors led to the continuity or change, and how do we classify any such continuity or change?

In this article, Dimitrova, Gürkan and Koops presents a general framework for capturing and systematicallyanalysing critical junctures and degrees of change in EU policies.

The growing demand of energy indicates that global energy resources in the form of fossil fuels will not be sufficient in the future. In order to solve potential future energy problems development of a sustainable hydrogen economy is highly desirable.

One of the most important puzzles in modern astrophysics is the nature of dark matter.

How can we understand the implementation of EU policy and what challenges are involved?

The role of the interfacial environment during electrochemical reactions has been increasingly valued, especially for those reactions involving protons or hydroxyl ions.

Green hydrogen is produced via a process called water electrolysis. During electrolysis water is split into oxygen and hydrogen.

This article, by Sara Perlstein, explores how perceived social acceptability shapes whether people talk about risks, showing that risk perceptions and conversations are socially negotiated rather than purely individual.

Planets are formed in disks of gas and dust around young stars.

Many of the big challenges of the 21st century (climate change, international migration, financial instability, socio-economic inequality) find their origins in the organisation of the global economy. Any solution to the world’s big challenges therefore requires forceful policy interventions at the…

The emissions of the Chinese industrial sector alone comprise 24.1% of global emissions (7.8 GtCyr−1 in 2015). This makes Chinese industrial emissions of unique national and international relevance in climate policy. This study reports a literature survey that quantitatively describes the evolution…

This thesis investigates the structural evolution and assembly of galaxies since the first few billions years after the big bang.

Sarah Giest, Assistant Professor at Leiden University, and Ishani Mukherjee researched the topic of 'Behavioural Insights Teams (BITs) and Policy Change: An Exploration of Impact, Location, and Temporality of Policy Advice'.

The goal of this thesis is to understand how interfacial parameters, such as the addition of organic additives, bulk pH or metal cations of the electrolyte, affect the relevant electrocatalytic reactions, i.e. electrochemical CO2 reduction reaction or hydrogen evolution reaction.
