The transition to multicellularity in eukaryotes appears to be intimately linked to the transition from isogamy (gametes of the same size) to anisogamy (gametes of distinct sizes), and indeed to oogamy, a form of anisogamy with a large, immotile egg and a motile sperm. Volvocine algae provide a useful and fascinating model to study how[…]
The project: Single-cell approaches are revolutionizing developmental biology. We can now trace in time the behavior of each cell in a live developing organism (1). In parallel, single-cell transcriptomics and genomics gives access to the transcriptional state of each cell (2). Combination of these two approaches promises to unravel how genomic information translates into individual[…]
This summer, the Company of Biologists, the not-for-profit publisher of Development, is running a Workshop on ‘Development and evolution of the human neocortex‘, organised by Victor Borrell, Wieland Huttner and Arnold Kriegstein. The Company of Biologists Workshops provide leading experts and early career scientists from a diverse range of scientific backgrounds with a stimulating environment for the cross-fertilisation[…]
A 2-year Postdoc position in “Comparative genomics and single-cell transcriptomics” is available at the Sars International Centre for Marine Molecular Biology, in the research group headed by Andreas Hejnol.
There is a vacancy for a PhD position (Early Stage Researcher) for a fixed term of 3 years at the Sars International Centre for Marine Molecular Biology affiliated with the project “Mesoderm Evolution”. This PhD position is subject to funding by the MSC Innovative Training Network “EvoCELL”. EvoCELL is a Marie Sklodowska-Curie Innovative Training Network aiming at studying the evolution of cell-types and tissues in a diverse array of vertebrates and invertebrates.
Author Summary of “A gene regulatory network for apical organ neurogenesis and its spatial control in sea star embryos”. Alys M. Cheatle Jarvela, Kristen A. Yankura, Veronica F. Hinman Development 2016 143: 4214-4223; doi: 10.1242/dev.134999 Very similar cell types are found across the animal tree of life. Much of animal diversity, therefore, arises not from the formation of new cells, but[…]
My research interest is the evolution of multicellularity. How did cells ‘learn’ to communicate with each other to build a structure that is more complex than its parts and shows new emergent behaviour? Which and how many new genes would be required to transform a unicellular ancestor into a well-organised multicellular structure? The Nature Communications[…]
We welcome you to join us for the inaugural meeting of the Pan-American Society for Evolutionary Developmental Biology, which will be held on the Clark Kerr Campus at the University of California Berkeley from August 5-9, 2015. The meeting will feature an exciting lineup of 22 invited plenary speakers with an incredible diversity of approaches[…]
The Minnesota Center for Philosophy of Science in the College of Liberal Arts at the University of Minnesota invites applications for a full-time postdoctoral position in conjunction with the project “Integrating Generic and Genetic Explanations of Biological Phenomena,” sponsored by the John Templeton Foundation. This project brings together scholars in philosophy and biology to address[…]
What is the earliest Phylum of metazoans to possess what we would recognize as a nervous system? Did earlier organisms have all the components of a nervous system in the absence of what we would recognize as neurons? What is a neuron? Did nervous systems evolve independently more than once? Where were all the molecular[…]
