Article
Full-text available
Animals and fungi have radically distinct morphologies, yet both evolved within the same eukaryotic supergroup: Opisthokonta1,2. Here we reconstructed the trajectory of genetic changes that accompanied the origin of Metazoa and Fungi since the divergence of Opisthokonta with a dataset that includes four novel genomes from crucial positions in the O...
Preprint
Microbial eukaryotes are diverse and ecologically important organisms, yet sampling constraints have hindered the understanding of their distribution and diversity in freshwater ecosystems. Metabarcoding has provided a powerful complement to traditional limnological studies, revealing an unprecedented diversity of protists in freshwater environment...

Article
Full-text available
The Holozoa clade comprises animals and several unicellular lineages (choanoflagellates, filastereans and teretosporeans). Understanding their full diversity is essential to address the origins of animals and other evolutionary questions. However, they are poorly known. To provide more insights into the real diversity of holozoans and check for und...

Understanding biological diversity is crucial for ecological and evolutionary studies. Even though a great part of animal diversity has already been documented, both morphological surveys and metabarcoding analyses have previously shown that some animal groups, such as Platyhelminthes, may harbour hidden diversity. To better understand the molecula...

Opisthokonta represents a major lineage of eukaryotes and includes fungi and metazoans, as well as other less known unicellular groups. The latter are paraphyletic assemblages that branch in between the former two groups, and thus are important for understanding the origin and early diversification of opisthokonts. The full range of their diversity...
Article
Full-text available
Animals with bilateral symmetry comprise the majority of the described species within Metazoa. However, the nature of the first bilaterian animal remains unknown. As most recent molecular phylogenies point to Xenacoelomorpha as the sister group to the rest of Bilateria, understanding their biology, ecology and diversity is key to reconstructing the...
Conference Paper
Allomaternal care (AMC) is present in all major primate radiations, and is abundant in primates relative to other mammals, suggesting strong selective pressure for AMC early in primate evolution. Despite this, we know little about what led to the expansion and diversification of AMC throughout the Order, including the proximate mechanisms promoting...

Project
During the last decade, many initiatives have been independently taken to explore the hidden marine microdiversity using the recently-emerged high-throughput technologies. As a result, a bulk of metabarcoding data was produced. In this project, we aim to combine various metabarcoding datasets regarding the phylum Platyhelminthes and analyze them under a phylogenetic prism. Our main objective is to get a better insight of the diversity of Platyhelminthes and to recognise novel, undescribed clades of the free-living representatives of this phylum.
