AI reads 3D tooth microwear to reconstruct diets of early human ancestors

The study of dental microwear allows the analysis of the microscopic marks that foods leave on the surface of tooth enamel during masticatio

The study of dental microwear allows the analysis of the microscopic marks that foods leave on the surface of tooth enamel during mastication. In paleoanthropology, this methodology helps reconstruct the diet of fossil primates and hominins throughout human evolution. The microscopic striations in dental enamel are like microscopic archives that reveal whether the diet was rich in foods with softer or more abrasive components. Now, a study published in the journal Scientific Reports presents an innovative artificial intelligence (AI)-based methodology for identifying 3D wear patterns consistently and independently of the analyst. These 3D wear patterns differ among primates inhabiting diverse ecosystems and following different diets. The study also identifies which variables are most informative for the classification of dental microwear and proposes an analytical framework open to the entire scientific community for studying this type of surface.

Okay listen, I love paleontology and etymology. I understand why this species of archaic human is named what it is.

But look me in the eyes and tell m the name "homo erectus" isn't funny

archeology/anthropology ask: thoughts on the neverending h. neledi discourse?

Fascinated nodding and the occasional "huh!" or "wow!" because hominin taxonomy is something I know VERY little about haha. I think H. ergaster is stupid and it's all just H. erectus, and I am still on the side of believing that H. heidelbergensis is the common ancestor of H. sapiens and H. neanderthalensis until given a good reason to believe otherwise, but I know almost nothing about H. naledi - certainly not enough to have an opinion on where it goes taxonomically! It's a weird one.

After years of rendering and months of setting up the showcase, I now present the finished video on my Hominin reconstructions lined up in Blender. Glad to finally have this one uploaded. In this video I present nine Hominin busts which I built up around fossil cranium scans from MorphoSource (or from Artec 3D), showing the edited bony material first, then muscles, cartilage, tendons, and eyeballs, and finally skins for each of the models in turn. A little apologetic for the audio quality here, between recovering from a headcold and not having dedicated recording equipment, but hopefully 12 minutes of that is survivable. Also my first time adding little musical stings I recorded myself. Enjoy!
