Are #choanoflagellates , #filastereans , #ichthyosporeans & #corallochytreans truly the best models for exploring animal origins?

While these lineages have been so far pivotal to address the origin of animals (and they surely will continue to be!!), eDNA has revealed that there

Our current reconstruction of the genetic content of the unicellular ancestor of animals. I can not insist enough, had not we studied filastereans, ichthyosporeans, corallochytreans & choanoflagellates, the story will be completely different. Different & inaccurate #animalorigins

#EMBOmarineImaging is over & it was a blast. A lovely #community is taking shape with more beautiful imaging of protists to come.
Now for a week of Sampling #Ichthyosporeans #Plankton #PlanExM

What a fantastic day! A big thank you to Patricia Suárez Ara for an incredible 4 years of PhD research pursuing the establishment of genetic tools in #ichthyosporeans & #corallochytreans ! Thanks to Sebastián R. Najle for co-supervising with such knowledge and enthusiasm. Thanks Núria Ros i

Andrej Ondracka presenting our work on #ichthyosporeans life cycle #protists in the origin of metazoans workshop

Had a fantastic day Iñaki Ruiz-Trillo. What a friendly lab and finally saw #filastereans and #ichthyosporeans under the microscope. Thanks.

The International Choanoflagellates & Friends Workshop will take place May 17-20, 2023 UC Berkeley & UC San Francisco.

Ichthyosporeans have a cell layer that resembles an epithelium and forms by a Drosophila-like cellularization mechanism. Great to see such beautiful cell biology in unicellular relatives of animals!

Looking forward to apply this on some ichthyosporeans!😍

How does #multicellularity emerge? Experimental #evolution of ichthyosporeans (unicellular cousins of animals) shows how cellular control of density & size drives sedimentation rate variation, shaping evolution of multicellularity Omaya Dudin 𓂆 ¦🍉¦ 🇵🇸 ¦🦠¦🔬¦ &co #PLOSBiology plos.io/3tMD8cu

Tomorrow, Arthur will talk about miRNAs in Ichthyosporeans. Second session of the morning in Stora Salen C17-04. Don't miss it! #EEDUppsala

A fascinating feature of animal origin is that all their known closest unicellular relatives have representatives with temporal #multicellular life stages. All of them. Choanos, filastereans, #ichthyosporeans , corallochytreans. 1/7 #evolution

Our review on how work on #protists ( #choanoflagellates #filastereans & #ichthyosporeans ) is illuminating animal origins Institute of Evolutionary Biology (IBE) twitter.com/ArnauSebe/stat…

Please join us in the next Biology Club presented by Dr Omaya Dudin Omaya Dudin 𓂆 ¦🍉¦ 🇵🇸 ¦🦠¦🔬¦ on Monday 16th October at 12:15pm in room 1S059.
Dr. Omaya Dudin is an SNSF Ambizione Fellow at EPFL and he will talk about 'Ichthyosporeans and the evolution of animals embryogenesis'.

There are protists more closely related to us than to other protists—choanoflagellates, filastereans, ichthyosporeans, apusozoans, and amoebozoans (also fungi are more closely related to us than plants).

#Ichthyosporeans such as S. arctica & C. perkinsii will always be at the core of our research, but we also plan to use #UExM to explore #multicellular developmental #diversity at different nodes of the tree of #Eukaryotes . 3/7
