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

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.

Are traces of fire use detectable in ancient hominin genomes?

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.…

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

Leiden archaeologist José Joordens has been awarded a Veni grant to develop her research on the role of climate change in early hominin evolution.

The Early Upper Palaeolithic (EUP) record throughout Europe is characterized by major changes in human behaviour.

In a letter initiated by Wil Roebroeks, among others, serious concerns were raised about three research papers claiming evidence for one of the earliest human occupations of Europe.

The Altai region has yielded a cluster of Middle and Upper Paleolithic stratified sites that have been recently excavated using a multidisciplinary approach.

How did toxin genes evolve from harmless physiological genes?

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…

Evolution & Biodiversity is one of the four research themes of the Institute of Biology Leiden.

Animal Sciences’ contributions to the Evolution & Biodiversity 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.

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

Do humans and zebra finches share cognitive mechanisms that are important for speech perception?

Microbial Sciences' contribution to the Evolution & Biodiversity 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.

Plant Sciences' contribution to the Evolution & Biodiversity 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.

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

Female and male songbirds sing equally elaborate songs in some species, but in others, females do not sing like males or not at all. How did such pronounced differences in male and female communication evolve?

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 order to compare languages, it is important to have a thorough knowledge of the specific languages you are studying. Gijsbert Rutten and his team are investigating the origin of Standard Dutch and the repression of ‘non-standard’ variants between 1750 and 1850.

The logic seems inescapable indeed. The bigger the population, the higher the probability it contains an Einstein. Hence, bigger populations are more likely to develop complex culture.

The Human Origins group at Leiden University studies the archaeology of hunter-gatherers, from the earliest stone tools in East Africa, more than three million years old, to the origin of sedentary societies towards the end of the last ice age.

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.

The Laboratory for Human Osteoarchaeoloy examines human remains and their burial context to address questions about the human past.

Birds sing to be heard, but how do they cope with increasing noise levels? Which species persist in cities and why? And do they thrive or suffer in the urban soundscape?

The first workshop will be about potentially setting up 3 different clusters.

To gain more insight into the evolutionary development of orchid flowers and fruits, the orchid species Erycina pusilla was studied. The evolutionary origin of the median petaloid sepal, the callus on the labellum, and the stelidia was studied.

As the flagship journal of the National Academy of Sciences USA, PNAS publishes several special features each year highlighting topics that are expected to engage the interest of the journal’s broad readership. Archaeologist Wil Roebroeks was invited by the Editors of PNAS to contribute a paper on the…

Human trafficking is a very topical social problem, which because of both its social and legal complexity, can only be studied in an interdisciplinary way. Combating human trafficking currently features high on national and international policy agendas.
