If you want to know the data, you have to read the literature. Here are the contents of the current issue of the American Journal of Physical Anthropology (Vol. 131, No. 3), just one of many journals dealing with the subject:
- Hindlimb adaptations in Ourayia and Chipetaia, relatively large-bodied omomyine primates from the Middle Eocene of Utah
- Khoratpithecus piriyai, a Late Miocene hominoid of Thailand
- Continuity of interpersonal violence between Nubian communities
- Late Chachapoya population structure prior to Inka conquest
- Osteoporosis in a population from medieval Norway
- Spondylolysis, spondylolisthesis, and lumbo-sacral morphology in a medieval English skeletal population
- Test of the Lamendin aging method on two historic skeletal samples
- Quantitative analysis of human mandibular shape using three-dimensional geometric morphometrics
- Orangutan positional behavior and the nature of arboreal locomotion in Hominoidea
- Elastic properties of external cortical bone in the craniofacial skeleton of the rhesus monkey
- Brief Communication: Linear enamel hypoplasia and the shift from irregular to regular provisioning in Cayo Santiago rhesus monkeys (Macaca mulatta)
- Evolution of genetically correlated traits: Tooth size and body size in baboons
- Brief communication: Identification of the authentic ancient DNA sequence in a human bone contaminated with modern DNA
- Ontogeny of facial dimorphism and patterns of individual development within one human population
A lot of this information is available online. Dig in and have fun!

I must be not qualified since I presently am wondering who was the parents of the third human on this planet..
