The International Biological Programme investigated the biology of
circumpolar human populations in the period 1967-1974. This research was
carried out by multidisciplinary teams and covered demography, genetics,
craniofacial development, growth, ophthalmology, nutrition physiology
and behaviour. The populations studied include Eskimos, Lapps and Ainu
as well as certain of those from Russia. The environment inhabited by
the populations has low temperatures, seasonal extremes of light and
dark and relatively meagre ecological resources, but despite such harsh
conditions the groups have survived for thousands of years. The study
elucidates the biological and behavioural processes leading to this
successful adaptation.
