I am happy to announce that we have a new paper out investigating the validity of species vs. genus taxonomy in the hominid fossil record.
A genotype:phenotype approach to testing taxonomic hypotheses in hominids (Brasil et al. 2020)
We note that genus-level taxonomy is much more informative in the fossil record, particularly when using biologically-meaningful phenotypes. This work uses our previously described dental phenotypes (MMC and PMM; Hlusko et al. 2016) and was led by Dr. Marianne Brasil. This research continues to build on our findings that MMC and PMM are heritable, independent of body size and sex, and have strong phylogenetic signal in mammals (Hlusko et al. 2016, Monson et al. 2019, Zuercher et al. 2020). This is the second application of these dental phenotypes to the hominid fossil record, following previous work from my lab that used machine learning to assess dental evolution in the fossil record (Monson et al. 2018). Research on MMC and PMM is ongoing. But for now, enjoy this paper on the biological philosophy of taxonomy in the fossil record!
I am excited to share the results of an ongoing international research collaboration with scientists in Spain and Turkey. This work develops new regression equations for estimating stature from the tibia with important implications for forensics. Stay tuned for part 2 of the research, hopefully out sometime this summer! As always, please contact me if you would like a pdf copy of our paper.
Piecewise regression equations for estimating stature: an anthropometric study in Spanish females
Despite everything that has been going on, I am excited to announce that a paper I started as a graduate student has now been published in The Anatomical Record. “Patterns and magnitudes of craniofacial covariation in extant cercopithecids” looks at cranial variation in African and Asian monkeys with a focus on the orbits and primate vision.
This work was also recently featured in Western Today with a great article written up by one their undergraduate interns. I encourage you to check it out!
Stay healthy out there!
I am excited to be offering a brand-new course for Spring Quarter, entitled ‘Evolution of Cognition.’ There are still spots available, so feel free to sign up. This course also fulfills the Writing Proficiency 3 requirement.
The goal of the course is to discuss the evolution of large brain size in primates and how it interacted with reproductive ecology (e.g., parental care, lactation and resource availability, changes in ovulation/estrus, and mating systems) as well as anatomical changes related to bipedality. Students will be asked to write a grant-proposal style paper on a topic of their choice, related to the class. This is a biology-heavy class focused on the evolution of cognition in our species and other primates (with comments on other animals, e.g., dolphins, canids, elephants), leading to humans today.
Fall quarter is officially up and running here at Western! I am teaching ANTH 215 Intro to Biological Anthropology this quarter. This class is designed to introduce students to the biological side of anthropology, including human osteology, primate paleontology, human evolution, and primate behavior, as well as comparative biology, evolutionary theory, and genetics. Additionally, this course addresses modern human biological variation from historical, comparative, evolutionary, biomedical, and cultural perspectives. I have a great group of students in my class, an excellent graduate student instructor running the labs, and I am looking forward to a great quarter!
I just got back from Prague where I attended and presented at ICVM 19. It was an excellent meeting with a lot of really interesting research, and it was great getting to talk science with so many colleagues! While I was there, I presented my ongoing work on human enamel-dentine junction morphology, and I was happy to receive a lot of really useful feedback on the research. I also got spend some time enjoying Prague – it is a beautiful city! Thank you ICVM 19, and I hope to see you in Australia in 2022!
I am happy to report that our new study came out this week in Ecology and Evolution! The paper is open-access and freely available.
This new research investigates the diversity of tooth morphology in mammals, finding that, contrary to previous assumptions, diet does not play a dominant role in the evolution of dental proportions. Instead, the study points to stabilizing selection as a key factor in understanding the diversity of tooth morphology in mammals. The study, a collaboration between scientists in the United States and France, looked at the teeth of more than 1,500 mammals held in museum collections in six countries to investigate the role of ancestry and diet on the evolution of dental proportions. This is the largest investigation of dental proportions to date.

I am honored to announce that I have accepted a position as Assistant Professor in the Department of Anthropology at Western Washington University, beginning fall 2009.
At Western, I will be running the Bioanthropology lab and teaching Intro to Bio Anth and Osteology. I will also be conducting research on primate evolution, life history, and reproductive ecology in conjunction with undergraduate and graduate researchers.
I am very excited to start this next chapter of my academic career, and I can’t wait to join the community and faculty at Western. It’s a dream to head back to the Pacific Northwest! And I am looking forward to working with Washington students in anthropology and biology, with goals of advancing science, science communication, and outreach.
