The evolutionary origins and consequences of human-commensalism in Passer sparrows

Objective

Human-commensal species are almost constantly present in our daily lives; they are the mice in our fields or the sparrows in our gardens. The evolutionary trajectories of these species are intertwined with our own through the development of agriculture and human civilization, yet we know surprisingly little about their origins.

My project, EVOSPARROW, will focus on Passer sparrows, including the House sparrow, one of the most ubiquitous commensal species. I will first use whole-genome resequencing to resolve the phylogeny of the Passer genus and provide context for the evolution of human commensalism. I will then make use of genomic data from over 120 individuals from across the Passer distribution to reconstruct the recent evolutionary history of sparrows in Europe. I will use coalescent models to test whether House sparrow migration into Europe is consistent with the introduction of agriculture during the Neolithic.

The consequences of commensal relationships have rarely been studied in an evolutionary context. Yet comparisons between commensal and non-commensal lineages offer a means to understand the phenotypic and genetic basis of adaptation to human modified niches. I will quantify behavioural and morphological phenotypes between commensal House sparrow populations and a non-commensal House sparrow lineage occurring in the Near East, as well as other non-commensal Passer species. I will then scan the genome to identify the genetic basis of these phenotypes and quantify their segregation in the wild.

With EVOSPARROW, I will develop an evolutionary framework to study how, when and dependency on the human niche arose in commensal species. Passer sparrows are the ideal system for this aim and with high-resolution genomic data, it is now possible to answer these questions. Through understanding the evolutionary origins and consequences of commensalism, I aim to also shed light on the development of our own civilization towards an agrarian society.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
