Virtual labs in Biological Anthropology
The COVID-19 crisis has been challenging for many instructors in biological anthropology. Our courses introduce students to the human skeleton, the anatomical diversity of non-human primates, and the fossil record of human evolution. In our teaching labs, students encounter real objects: human and non-human primate skeletal material and casts of fossils. Many students learn better from seeing and touching these objects than they can learn from lectures or reading. So being out of the lab is tough.
I've been teaching online since 2013. Until now I've never found a very satisfying way to present laboratory materials in a virtual 3D setting. Biological anthropology is a comparative science, and that means students need to be able to compare materials with each other. There are some great online resources with 3D data. But using 3D models usually requires students to download and learn special software, and none of these software packages make it easy to set up comparisons that show multiple objects in the same orientation and scale.
- The virtual labs work on phones, on iPads and other tablets, and on laptops and desktops using modern browsers. I find that they do not work on my oldest (2010-2013) iPads or older browsers.
- Just as with any process of reproducing or depicting skeletal remains, it is important to understand the limitations of this format. I've described the process and limitations in some detail on the Virtual Lab Frequently Asked Questions page.
- These virtual labs include anatomical models and not scans. In many cases, the creation of the model begins with a 3D surface scan of a bone or fossil. In others, the process begins from anatomical models built by artists. These are learning aids and are not suitable for research measurements.
- The virtual labs do not include models that can be extracted or printed. For those interested in 3D printable models, I have included links to resources in each virtual lab.
If you are an instructor and are interested in building some of these virtual labs into your course, please reach out to me. I do have self-contained virtual labs that I deploy on Canvas for my own students, which may be a better option for some courses than external links to my lab website. I also have some virtual labs that I am not releasing yet to the public. If these would be useful for your courses, I would love to hear from you.
My laboratory is sharing these low-resolution virtual laboratories exclusively for educational purposes. These virtual labs are available under a Creative Commons-Attribution-Noncommercial (CC-BY-NC) license. The construction of the virtual labs requires a low poly-count 3D representation of skeletal material that is not useful for printing, research, or commercial reproduction. My commitment with all educational materials is for them to work well on a phone, bringing them into reach for students worldwide outside of university settings. My lab's work with these materials is made possible by the scientific collaboration of many institutions around the world. The sources for anatomical models and data are listed in each virtual lab. In addition, I have linked sources for high-resolution 3D data and anatomical models where they exist for each specimen.
