1. Adaptive divergence in fission yeast : From experimental evolution to evolutionary genomics
Abstract : How adaptation and population differentiation occur is fundamental to understand the origin of biodiversity. Work in speciation alongside the increased ease of generating genomic data have allowed the exploration of genomic changes relevant to adaptation. READ MORE

2. Divergence, admixture and continuity in the human past : Demographic inference using ancient and modern genomes
Abstract : Demographic forces shaping the genetic variation we observe today can include population divergences, admixture events and continuity through time. The advancement of high-throughput sequencing technologies, together with developments in molecular and bio-informatics methods, mean the number of ancient genomes available for inference has risen steeply.

3. Dating Divergence Times in Phylogenies
Abstract : This thesis concerns different aspects of dating divergence times in phylogenetic trees, using molecular data and multiple fossil age constraints.Datings of phylogenetically basal eudicots, monocots and modern birds (Neoaves) are presented. Large phylograms and multiple fossil constraints were used in all these studies. READ MORE

4. Postmating Sexual Selection and its Role in Population Divergence in Beetles
Abstract : Speciation is the process describing the formation of new species and is at the heart of evolutionary biology. According to the biological species concept only reproductively isolated forms are regarded good species. This thesis aims at identifying evolutionary processes that cause population divergence and, ultimately, speciation. READ MORE
