/ 🧵 Setting the stage. We have 5 faces. Are they 5 people or 5 iterations of one blueprint? Using 60+ anthropometric ratios (trichion to gnathion), we move past subjective "vibes" into high-dimensional data. This thread explores why the math says these aren't just strangers. We are looking at a skeletal MAC address that defies biography. Let's dive into the statistics of the uncanny. #DataScience #Morphometrics #Bayesian #Stats #SimulationTheory

They did morphometrics on the Chicago Rat Hole and concluded that its likely a squirrel. Published in Biology Letters, "Rodent indent not self-evident: a case of mistaken identity of the 'Chicago Rat Hole'".

#30DayChartChallenge Día 15: Complicated Relationships! 🐧↔️🐧

Hoy, una matriz de scatter plots con ggpairs para explorar las relaciones entre medidas corporales (Long. Pico, Long. Aleta, Masa Corporal) en los pingüinos de Palmer. ¡Perfecto para el prompt "Complicated"! #RelationshipsWeek #Animals

La matriz lo enseña todo:
* Diagonal: Distribución de cada medida (densidad).
* Abajo: Scatter plots de cada par de medidas (coloreado por Especie).
* Arriba: ¡La correlación $ entre ellas!

Se ven las fuertes relaciones positivas (más grande = aleta más larga) y cómo las especies (Adelie, Chinstrap, Gentoo) forman clusters distintos en este espacio de rasgos. ¡Una forma densa de ver muchas relaciones a la vez!

Idiosyncratic #paleontology paper of the week for #fossilfriday: modularity a hot topic for a decade now, and here's one way of operationalize it to look at simplification and stasis in turtle shells.

Reduction, reorganization and stasis in the evolution of turtle shell elements

Abstract. Novel phenotypic configurations can profoundly alter the evolutionary trajectories of species. Although innovation can precede lengthy periods of evol

Extremely happy for Gabriele Sansalone. Gabriele has been a postdoc in my lab for almost two years. He has just left the lab to become a #newPI at the University of Modena and Reggio Emilia. I whish him the best of luck in this new endeavour and to establish a successful lab! https://www.fruciano.org/events/postdoc-gabriele-sansalone-leaves-the-lab-to-become-a-pi/ #evolution #morphometrics #anatomy #geometricmorphometrics

I recently accepted a position as Associate Professor at the University of Catania (my alma mater). This is essentially the next rank compared to my current tenured research-only position. I will move my lab in the fall. https://www.fruciano.org/events/the-lab-will-move-to-the-university-of-catania-in-the-fall/ #evolution #morphometrics #zoology #biology #academicchatter #geometricmorphometrics
