The Hominid Paleobiology Laboratory focuses on increasing our understanding of human evolution by exploring new sources of evidence, analyzing the existing fossil record and using the comparative method in innovative ways. Most of the Hominid Paleobiology Lab research is conducted in collaborating laboratories in Finland, Italy, Spain, the United Kingdom and the United States.
Extant apes and modern humans are relics of a diverse radiation of apes from the Miocene epoch (23 to 5.3 million years ago). One of these — still unidentified — fossil apes was the common ancestor of chimpanzees, bonobos and modern humans. Research in the Hominid Paleobiology Lab focuses on improving our ability to recognize hominin species and genera and reconstruct higher primate phylogeny using evidence from the fossil record.
Recent research projects include:
- Investigating the molecular control of regions prone to homoplasy (e.g., teeth, cranial base or another characteristic shared by a set of species but not present in their common ancestor)
- Using dental histology to determine if apparently similar morphology at the macrostructural level has the same microstructural basis
- Employing micro-CT technology to image the enamel-dentine junction (EDJ) and compare its performance for taxonomy and systematics to that of the outer enamel surface
- Examining the comparative anatomy of soft tissues to determine whether hard tissues are especially prone to homoplasy
Lab interests also include understanding the comparative context of species diversity and adaptive shifts within the hominin clade, improving our understanding of the evolution and comparative context of hominin dental morphology, the molecular evolution of the nuclear receptors and assessing patterns of molecular sequence change to identify candidate genes, primate comparative anatomy and promoting access to data and information about museum collections of higher primates.
