AI Article Synopsis
- The Homo genus is characterized by a notable increase in brain size, with modern humans considered the pinnacle of this evolutionary trend.
- Many studies emphasize the growing brain size in the Homo lineage but often overlook the brain sizes of smaller-brained hominins like Homo floresiensis and Homo naledi.
- This review highlights the advantages of employing phylogenetic comparative methods to better understand the complexities of hominin brain evolution and the limitations of ignoring these approaches.
Article Abstract
An absolutely and relatively large brain has traditionally been viewed as a distinctive characteristic of the Homo genus, with anatomically modern humans presented at the apex of a long line of progressive increases in encephalization. Many studies continue to focus attention on increasing brain size in the Homo genus, while excluding measures of absolute and relative brain size of more geologically recent, smaller brained, hominins such as Homo floresiensis, and Homo naledi and smaller brained Homo erectus specimens. This review discusses the benefits of using phylogenetic comparative methods to trace the diverse changes in hominin brain evolution and the drawbacks of not doing so.
