Well that's impressive!! They just published the first massive phenomics dataset spanning the #ants tree of life, with 2,000+ whole-body 3D scans!

Can't wait to use this to integrate molecular and phenotipic studies! #bugsky #phylogenetics #genomics 🧬🖥️🐜

NEW PAPER OUT 🖤 another one of pure comparative #genomics

We investigated the molecular & genome #evolution of tadpole shrimps, a group of #crustaceans with a sharp morphological stasis. Also sequenced 2 new genomes 🧬🦐

Haplodiploidy has been repeatedly reported as one of the factors promoting altruism & eusociality in #insects 🐝🐜🪳

Well apparently it's not! Different statistical approaches find no relationships between the two, in this brand new phylogenetic work!

Kosakyan et al. sequenced mitogenomes of species from the two main lineages of the Gastrotricha; they found stable mitogenomes in the mostly freshwater Chaetonotida, but a dynamic pattern in the the marine Macrodasyida.

A gigantic work by some Italian colleagues on how ants have been used as biological control agents all around the globe: more than 180 published papers have been reviewed!

Guess what, also the story of our beloved red wood ant is mentioned 🫶🐜 #bugsky

Independent origins of spicules reconcile paleontological and molecular evidence of sponge evolutionary history Sponges have a cryptic Ediacaran history because ancestral sponges were soft-bodied and had low fossilization potential.

Our latest: Independent origins of spicules reconcile paleontological and molecular evidence of sponge evolutionary history, led by @meleonora-rossi.bsky.social with help from friends @bristolpalaeo.bsky.social including @anariesgo.bsky.social @evopalaeo.bsky.social Davide Pisani and many others

Wish our authors and readers a Happy Holiday & a fruitful 2026!🥳🥳🥳

Look mum, I'm famous! 🖥️🧬🐜

Thanks! I must admit that it took me longer to assemble this graphics rather than producing the tree itself 😆

2/2🧵 Call me a nerd, but my brain goes crazy for #phylogenetic trees: I find them elegant and easy to read! So I couldn't help but to draw one for my #invertober2025 wrap-up 🖥️🧬

I also run a series of basics stats 👀 see them below and find the full explanation on github.com/filonico/inv...

Just gave a seminar on the #genomics of #SexDet for students of the uni of Bologna.

I included these wonderful plates by Nettie M Stevens, the scientist who first linked XY chromosomes to SexDet: she was a woman and, guess what, she is rarely acknowledged for her work

Is it sponges (panels A & B) or comb jellies (C & D) that root the animal tree of life?

This is the end 💥 I approached #invertober with no clear expectations, and now I can say it was exciting+painful+rewarding+exhausting! #SciArt

What's the most appropriate subject for Day 31 of #invertober2025 if not the death's-head hawk moth?

Stay tuned as I'll be publishing a wrap-up soon 👀

Ant systematics: past, present, and future Abstract. The classification of ants (Hymenoptera: Formicidae) has progressed in waves since the first 17 species were described by Linnaeus in the 1758 ed

Dias et al. used genetic data from 27 Drosophilidae species and 6 outgroups to reconstruct the evolutionary relationships of fruit flies, recovering Drosophilidae as nonmonophyletic, underscoring the need for taxonomic revision.

And now I'm just missing the last invertober 🥹 I can finally rest

a cartoon character says " unacceptable " in front of a turtle ALT: a cartoon character says " unacceptable " in front of a turtle

I know I could've just drawn the head part of the worm coming out from the sand, but that was *unacceptable* for my OCD (see below for how to read this)

Eventually it's me to blame...

Also, that would have not complied with the rest of my invertober and the final project I have in mind 👀

BEHOLD y'all the hecking bloody bobbit worm, who finally decided to get out from their sand burrow for the begone Day 14 of #invertober2025 #MarineLife

This took way longer than I expected (3 sessions of 2+ hours each). The problem was not the body structure itself, but the freaking segments 💀

3/3 🧵 Sometimes I find myself wondering if I'm suited for this work (or maybe if this work is suited for me?), especially for the pace it demands.

I believe we can build a work culture that values both sustainable rhythms and good science. But will the rest of the (reasearch) world accept that?

2/3 🧵 Dont get me wrong, I'm not referring to research itself—which is truly beatiful and rewarding—but to the way we do it.

I was taught that scientific research takes time, that "in-depth thinking is in the end what the academic world is about". But then, how come ppl do the exact opposite??

1/3 🧵 Im entering my 2nd year as a postdoc, & since Ive started my journey in academia I can't help but asking myself:

is this work culture sustainable? is this what I want to do for the rest of my life?
