Culture out of Africa next chapter The Contradictory Diversity of Anthropoid Societies Evolutionary equilibrium means that a strategy has to be optimal to any changes either sex might inflict, or any defection from the game theoretic equilibrium the situation might present. In the context of sex this means that societies need to reflect the complementary interplay between the vastly differing reproductive investments females and males make, the one massive and forthright, and the other opportunistic and competitive. Diverse ape societies derive their complexity and viability through responding to this sexual interplay, without the extensive capacity humans have for imposing 'artificial' cultural structures upon it. The relative clumping or diffuse nature of plant foods, determine, through the female foraging distribution, and the opportunities it provides males, whether ape species are monogamous very dispersed femalesform harems clumping sufficient for one male to guard several females - e.
Regional differences in modern human facial features are present at birth, and ontogenetic allometry contributes to variation in adults.
However, details regarding differential rates of growth and timing among regional groups are lacking. We explore ontogenetic and static allometry in a cross-sectional sample spanning Africa, Europe and North America, and evaluate tempo and mode in two regional groups with very different adult facial morphology, the Khoisan and Inuit.

Semilandmark geometric morphometric methods, multivariate statistics and growth simulations were used to quantify and compare patterns of facial growth and development.
Regional-specific facial morphology develops early in ontogeny. The Inuit has the most distinct morphology and exhibits heterochronic differences in development compared to other regional groups. Allometric patterns differ during early postnatal development, when significant increases in size are coupled with large amounts of shape changes.
All regional groups share a common adult static allometric trajectory, which can be attributed to sexual dimorphism, and the corresponding allometric shape changes resemble developmental patterns during later ontogeny.
The amount and pattern of growth and development may not be shared between regional groups, indicating that a certain degree of flexibility is allowed for in order to achieve adult size. In early postnatal development the face is less constrained compared to other parts of the cranium allowing for greater evolvability.
The early development of region-specific facial features combined with heterochronic differences in timing or rate of growth, reflected in differences in facial size, suggest different patterns of postnatal growth.In astronomy, an irregular moon, Physical characteristics Size Dynamical groupings of irregular satellites can be identified using these criteria and the likelihood of the common origin from a break-up evaluated.

The Shelter Characteristics of Traditional-styled Inuit Snow Houses The shelter value of snow iglus at Resolute (74 41 N, 94 54 W) in the Canadian High Arctic was assessed.
After a survey of snow conditions, construction sites were chosen and two iglus were built and furnished in a traditional way.
