A biоlоgicаl аnthrоpologist notices thаt a newly discovered hominin fossil has unusually thick leg bones compared to other fossils from the same time period. Curious about this observation, the researcher reviews previous studies on fossil anatomy and locomotion. The researcher then measures leg bones from 120 hominin fossils representing several species and compares the results statistically. The analysis shows that species with thicker leg bones are consistently associated with evidence of more terrestrial locomotion. The researcher concludes that thicker leg bones may have been advantageous for spending more time on the ground and publishes the findings in a peer-reviewed journal.
A biоlоgicаl аnthrоpologist notices thаt children in one mountain community are shorter than children in a nearby lowland community. Instead of immediately concluding that genetics explains the difference, the researcher also studies nutrition, disease exposure, altitude, cultural food practices, economic resources, and family history before drawing conclusions. Which anthropological approach is best illustrated by this research?
