Recently, however, a long and detailed study of fairly large groups of crania of both people has been made.[119] The results of this investigation suggest that, while there are some differences between the two series, they are not of great significance and that, therefore, the Basketmakers and the Pueblos were basically the same people. This is confirmed by cultural evidence, for, although changes occurred, there is a strong continuity of development from Basketmaker to early Pueblo times. Possibly there was some coming in of new people, who introduced new ideas which gave impetus to the cultural development; but it is now difficult to accept the theory of a mass invasion by a racially different group and of a radical change in physical type. In the light of this new evidence some archaeologists feel that the term “Anasazi” should be dropped, and the entire [culture], including the Basketmaker and Pueblo phases, should be called “Pueblo” or “Puebloan.”[7]

One factor which tended to make the Pueblo people seem extremely broad-headed was the habit of deforming the skull posteriorly, a practice which became almost universal in Pueblo times. A skull markedly flattened in back inevitably appears broader than one which is undeformed. This effect is believed to have been produced by strapping babies against hard cradle-boards or by using a hard head-rest. The soft skull of the infant was flattened by pressure in the back and, as the bones grew and hardened, this deformity became permanent.

The question naturally arises: Why did people wish to have deformed skulls? We cannot be sure of the answer, of course, but it seems possible that it represents nothing more than a matter of fashion and a change in ideals of beauty. Even in our own society there are fashions in physical appearance as well as in clothing and adornment. One need only compare the corn-fed curves of the Floradora sextette with the emaciated lines of “flappers” of the 1920’s to realize that we have little eccentricities of our own which might seem incomprehensible to a prehistoric Indian.

Important changes which mark the transition between the Basketmaker era and Pueblo times occurred in the realm of architecture. There are also differences between the first half of the Developmental Pueblo period, sometimes known as “Pueblo I,” and the second half which is sometimes called “Pueblo II.” In a general way we can trace the evolutionary development from pit houses, with associated granaries, to the fairly [complex] surface domiciles and subterranean ceremonial chambers of the final [phase] of the period.[113] Progress did not follow the same pattern in all places, however, nor did all similar changes occur at the same time.

As was noted in the preceding section, a few surface houses were built in the Modified-Basketmaker period, but this type of architecture did not become well established until Developmental-Pueblo times. In the beginning of the period, in most areas, pit houses were still the usual form of dwelling. To the west and north of these houses, granaries were built with superstructures in the form of truncated pyramids. Sometimes stone slabs and sometimes crude masonry were used in their construction.

Later, [jacal] structures as well as pit houses served as dwellings. The name jacal is applied to a type of construction in which walls are made of poles set at short intervals and heavily plastered with adobe. At first, walls sloped inward, as they had in the superstructures of the earlier granaries from which it is believed that this type of house was derived. Later, walls were perpendicular and the jacal construction was sometimes combined with masonry. Still later, masonry was used almost exclusively. As time went by, floors became progressively less depressed. In early forms, rooms were not connected, but eventually contiguous rooms became the rule, and, in the course of time, there arose multiroomed structures, sometimes called unit houses. Associated with these were highly specialized subterranean structures, used for religious purposes, but apparently derived from the old domiciliary pit house.

It cannot be stressed too strongly that these are all general statements, designed solely to show evolutionary trends during this period. Actually the situation is far more [complex] than this would indicate. In some sections, big pueblos were built very early in the period.[7] In peripheral regions, pit houses continued to be used as dwellings long after they had ceased to serve such a purpose in the main area, and, even in the nuclear portion, the rate of progress was by no means constant, nor was it always in the same direction. For a somewhat clearer picture, it is best to consider some of the different places where excavation of Developmental-Pueblo sites has been undertaken.

At Kiatuthlana, Arizona,[107] forty miles southwest of Zuñi, pit houses and [jacal] structures were contemporaneous during early Pueblo times. The latter were flat-roofed, four-sided buildings, trapezoidal, rather than rectangular, in outline. Some were single rooms, and others had three or four chambers.
