A domino effect on brain developmental evolution

Posted by on December 6th, 2019

The discipline “Evo-devo” studies the developmental basis of morphological evolution. In the field, some original animal models are emerging as interesting model organisms, enriching the knowledge in the field more and more. In the DECA team (Développement et évolution du cerveau antérieur, in French) we use an Evo-devo approach to study the developmental mechanisms responsible[…]

How do new cell types evolve? Sea urchins show the way….

Posted by on November 21st, 2019

We know surprisingly little about how evolution has created new cell types. One of the best examples of a recently evolved cell type comes from early sea urchin development. Most sea urchins produce a group of early embryonic cells known as micromeres- four small blastomeres that form by unequal cell division at the vegetal pole[…]

Discovering the Genetic Basis of Mimetic Color Diversity in Bumble Bees

Posted by on August 20th, 2019

As a first-year graduate student, I had the good fortune of accompanying Dr. Pierre Rasmont (U. Mons, Belgium) and his lab group on an expedition to collect bumble bees in Turkey. At our first stop onto the dry but flower-rich volcanic lands, we each dispersed to collect bees. At the time I was working to[…]

Genetics Unzipped podcast: Sex and death

Posted by on August 15th, 2019

We’re telling tales of sex and death, and exploring the very darkest side of genetics.

A day in the life of an onychophoran lab

Posted by on August 7th, 2019

What are onychophorans and why do we study them? My name is Sandra Treffkorn, and I recently finished my PhD in the department of zoology lead by Georg Mayer at the University of Kassel, Germany. In our research group, we focus on studying the evolution of animal diversity by investigating two very interesting but largely[…]

Postdoc Helsinki: Models of organ pattern formation of morphogenesis

Posted by on July 19th, 2019

1.Basic job and project description: 1.Job/ project description: The postdoc could choose between three main research projects: a. Mathematical modeling of phenotypic evolution in populations with embryonic development. b. Mathematical modeling of gene network and embryonic development evolution. c. Mathematical modeling of organ development and their evolution in mammalian teeth or Drosophila wing or some[…]

A day in the life of a Termite lab

Posted by on May 31st, 2019

How do genes and their environment interact during development and evolution to generate phenotypic diversity? To answer these questions in the Miura lab, by focusing on diverse animal taxa, we are studying physiological and developmental mechanisms of phenotypic changes in animal life cycles in response to environmental shifts. By the way, I’m Kohei Oguchi, a[…]

Genetics Unzipped podcast: Darwin vs Mendel

Posted by on May 8th, 2019

In this episode of Genetics Unzipped we ask, what would have happened if Darwin had read Mendel? And what if they’d been on Twitter?

Reflections on the ‘Evo-chromo’ Workshop (November 2018)

Posted by on March 5th, 2019

Alexander Blackwell and James Gahan   At the beginning of November 2018, thirty researchers congregated at Wiston House to attend a workshop titled ‘Evo-chromo: towards an integrative approach of chromatin dynamics across eukaryotes’. The workshop was organised by Frederic Berger (Gregor Mendel Institute) and Ines Anna Drinnenberg (Institut Curie), and was the 27th workshop hosted[…]

Sex combs in motion

Posted by on November 14th, 2018

Using computer simulations and mathematical modeling to study the evolution of morphogenesis   Juan N. Malagon and Ernest Ho tell the story behind their recent paper in PLOS Computational Biology. In the Larsen lab, we are interested in testing a 50-year old question: How do sex combs rotate in fruit flies? Despite extensive studies of the[…]
