Cynic's Corner: Sheep, maybe -- since even a living sheep can't provide verbal or written confirmation of what sex category it considers itself to be in.
But obviously, AI assistance cannot be used for determining the sex of human remains (based solely on those remains). We have it on authority from SciAm (that great left-wing savior of science magazines) that sex is a spectrum.
History has demonstrated that "binary sex" is socially oppressive, so politics trumps nature or physical facts. Accordingly, only a living person or historical records that a deceased individual once approved can provide confirmation of where they slot on the sex gradient.

Male or Female? AI enables sex determination of sheep based on their talus bone

PRESS RELEASE: The new study could make it much easier for researchers to determine the sex of archaeological animal finds in the future: with the help of AI-based algorithms, the sex of sheep can be determined quickly and easily – and only on the basis of four different measurements of their ankle bone, scientifically called the talus (plural tali). The advantage of the application, especially for archaeological finds, is obvious: the ankle bones of sheep or cattle are relatively small and compact and are therefore usually well and completely preserved in archaeological sites. An interdisciplinary team of researchers from the Bavarian State Collections of Natural History (SNSB) and the LMU München tested various machine-learning algorithms for their study.
“The accuracy rate of the AI algorithms is high,” says Nadine Schüler, first author of the study and scientist at the State Collection for Palaeonanatomy Munich (SNSB-SPM) and LMU München. ”Most algorithms determine the sex correctly - up to 70 percent, some variants even manage up to 90 percent.”
Traditionally, zoologists have used morphology to determine the sex of animals. In practice, they assess typical skeletal elements for each species, such as the pelvic bone in sheep and cattle. However, this approach is problematic for archaeological animal finds, where only fragments of the bones are usually preserved; this makes it difficult even for experts to distinguish with certainty between male and female animals. DNA analysis would be one solution, but it is costly and also requires damage to the archaeological animal remains.
“Machine learning could be the solution, but it is rarely used in archaeozoology. In medicine AI is already used to classify human bones. Our study is a first step towards applying the methodology to archaeozoological data. The AI-based sexing method provides archaeozoologists with a quick initial assessment of their finds,” Nadine Schüler continues.
For their study, the researchers “trained” various AI algorithms using over 240 sheep ankle bones for which the sex was known. The program learned to distinguish the tali of male and female animals. The “learned” method was successfully applied to 170 as-yet-unidentified sheep ankle bones from an archaeological excavation site in Mongolia.
