It borrows methods and techniques developed from skeletal biology and osteology and applies them to cases of forensic importance. When we take these methods and apply them to unknown modern human remains, with the aim of establishing identity or manner of death, then we are practicing the forensic application of osteology. From there, you can specialize in how to use osteology in forensic cases. Those of you who are unable to find degree programs in forensic anthropology should limit your search to physical anthropology, then focus on osteology or skeletal biology, and finally look for people who do forensic cases. Forensic anthropologists are experienced osteologists.
Forensic pathologists are medical doctors, physicians, with a specialization in forensic pathology.
Causes of death may be classified different ways such as natural, accidental, suicidal, homicidal, etc. Basically, all forensic anthropologists are anthropologists, but not all anthropologists are forensic anthropologists. At the undergraduate level, you do not want to specialize. From a solid foundation, you can then branch out and specialize. Statistics would be great, and is highly recommended.
