Super excited to share that my first first-author paper is ~finally~ published! I started working on chrY back in 2018 as a college freshman, using it as a phylogeographic marker for foxes. 8 years later, I’m wrapping up my PhD focused on chrY evolution. Big moment for me in many ways. :’)

TBH I’ve been overwhelmed, and occasionally discouraged, by the world recently. I was awarded best talk at a symposium last week. One of the judge’s comments was “presenter’s enthusiasm and passion for her research is contagious.” 🥲 ‘Twas a much needed win. My love for science will not falter!

Besides being adorable tactical assault possums, ALMOST ALL ARMADILLOS ARE BORN AS IDENTICAL QUADRUPLETS. (sorry, I *have* to shout this) It's a quirk of their reproductive system called polyembryony, an adaptation to an incredibly small implantation site in the 'dillo uterus.
Texas State Parks posted this on the other site.  It's four identical armadillos on a grassy open area.  Each leathery armored dillo is facing a different direction.
