Finally in the 19th century, Western medicine was introduced at the local level by Christian medical missionaries from the London Missionary Society (Britain), the Methodist Church (Britain) and the Presbyterian Church (US). Benjamin Hobson (1816–1873) in 1839, set up a highly successful Wai Ai Clinic in Guangzhou, China.[33] The Hong Kong College of Medicine for Chinese was founded in 1887 by the London Missionary Society, with its first graduate (in 1892) being Sun Yat-sen, who later led the Chinese Revolution (1911). The Hong Kong College of Medicine for Chinese was the forerunner of the School of Medicine of the University of Hong Kong, which started in 1911.

There  are more examples, and collective they provide a compelling case that evolutionary principles are important to understanding populations, genetics, infectious diseasease, diet, and other issues of public health – in diagnosis, treatment, and research. Therefore, the authors argue, evolution is an important topic for medical professionals to understand, and I completely agree.

At the University of Bologna the training of physicians began in 1219. The Italian city attracted students from across Europe. Taddeo Alderotti built a tradition of medical education that established the characteristic features of Italian learned medicine and was copied by medical schools elsewhere. Turisanus (d. 1320) was his student.[87] The curriculum was revised and strengthened in 1560–1590.[88] A representative professor was Julius Caesar Aranzi (Arantius) (1530–89). He became Professor of Anatomy and Surgery at the University of Bologna in 1556, where he established anatomy as a major branch of medicine for the first time. Aranzi combined anatomy with a description of pathological processes, based largely on his own research, Galen, and the work of his contemporary Italians. Aranzi discovered the 'Nodules of Aranzio' in the semilunar valves of the heart and wrote the first description of the superior levator palpebral and the coracobrachialis muscles. His books (in Latin) covered surgical techniques for many conditions, including hydrocephalus, nasal polyp, goitre and tumours to phimosis, ascites, haemorrhoids, anal abscess and fistulae.[89]
James pieces together the last twenty five to forty years from the elders of which functional medicine was created. The basis of Functional Medicine is in history of Naturopathic, Chiropractic and Acupuncture along with the nutritional and medical research worlds. The new terminology fits within the paradigm of medicine and allows those in the medical field to grasp the root concepts that have been spoken for the last several hundred to four thousand years. Only now is the science finally catching up to what has been spoken by the elders in those professions.
