Testing Zimmermann’s Telome Theory

Posted by on August 1st, 2018

A perspective on our recent paper ‘CLAVATA was a genetic novelty for the morphological innovation of 3D growth in land plants’1.   In the 1950’s, the German botanist Walter Zimmermann (photo here) hypothesized a series of developmental transitions enabling plant forms to radiate during evolution2. Zimmermann’s so-called Telome Theory has received much attention from those[…]

Evo-chromo: towards an integrative approach of chromatin dynamics across eukaryotes

Posted by on July 18th, 2018

***Deadline to apply for funded ECR places is July 20!***   In November, the Company of Biologists is hosting the latest in its series of Workshops. ‘Evo-chromo’ aims to integrate skills and interests of the fields of chromatin biology and evolutionary biology – if you are an early career researcher and this all sounds appealing[…]

The people behind the papers – Sa Geng & James Umen

Posted by on April 19th, 2018

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[…]

PhD position: Single-cell elucidation of the evolution of an embryonic transcriptional programme

Posted by on April 3rd, 2018

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[…]

Funded places for early-career researchers at a human brain development & evolution workshop

Posted by on March 8th, 2018

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[…]

ERC-funded postdoctoral-grade Research Fellow (m/f) in Comparative genomics/Single-cell transcriptomics of animals

Posted by on February 8th, 2018

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.

EvoCELL Research Fellow (PhD candidate) in Mesoderm Evolution: Formation of gonads and germ line during early embryogenesis

Posted by on February 8th, 2018

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.

How to build and evolve a nervous system

Posted by on November 20th, 2016

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[…]

How many and which genes for multicellularity?

Posted by on August 9th, 2016

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[…]
