This paper is one of the fruits of an expedition to Eastern Cuba in January and February, 1952. The names of many individuals who aided these investigations in various ways will be mentioned later in the course of this work. Authorities of the Universided de Oriente in Santiago de Cuba procured the indispensable cooperation of all the families in Santiago whose data are recorded here. I wish to thank all the individuals concerned for the friendly way in which they cooperated, permitting records and photographs, as well as blood specimens to be taken, and for the interest they showed in this work. I was also able to make a study of Indians and their descendants in Eastern Cuba, which has been published elsewhere (Gates 1954a).

Introduction

Many records of the results of various racial crosses have been made, some of which will be referred to later. These studies have been partly on the inheritance of characters which are from one point of view qualitative, such as skin color, eye-folds and hair characters, but the emphasis has frequently been on purely quantitative characters, based on anthropometric measurements. These results have previously been generally treated as a matter of population statistics, not based on individual pedigrees.

Trevor (1953) has carefully analyzed the inheritance results to be derived from the investigations of metrical characters in racial crossing. Selecting the nine investigations which are sufficiently extensive to yield results having statistical significance, he finds that in some cases the hybrid series are more variable, in others less variable than the populations which are chosen as more or less representative of the original parents. This mixed result is not surprising when one recognizes that the populations chosen as “parental” must differ more or less markedly from the actual ancestors of the hybrid populations. In fact, much difficulty was encountered in selecting populations as presumptively equivalent to the parents of the various crosses, since they had to be groups in which sufficient anthropometric measurements had been made. But notwithstanding the many…

This paper is an attempt to apply genetical methods to the study of inter-racial crossing. In the anthropological studies which have hitherto been made of racial crosses, masses of anthropometric measurements have frequently been taken, which are capable, when analysed, of furnishing valuable evidence on many points. Rut it is seldom possible to extract from them the kind of evidence the geneticist wishes to have concerning the inheritance of individual character-differences. Anthropological measurements are quantitative and require statistical treatment. The inheritance of sizes and especially of shapes is the most difficult field in genetics, and much has still to be learned from experiments with animals and plants before it can be clearly applied to man. Such features as the colour of skin, eyes, and hair, or shape of the hair in cross-section, while often presenting qualitative racial differences, also require measurements for a complete analysis of their inheritance, since intermediate grades usually occur in the hybrids. But they have the advantage that the extreme conditions at least are easily recognizable as qualitatively distinct, while this may not be evident with a mean difference in, for instance, stature or cephalic index.

The difficulties of applying the genetical pedigree method to haphazard human matings are very great. Nevertheless, it is so important that this method should be taken up by anthropologists, in addition to the traditional biometric methods of studying racial differences, that I venture to put forward these necessarily very incomplete results. In the biometrical method, the individual is measured as one of a population, but no sufficient account is taken of his relation to others. The purpose of the genetical method is to trace individual pedigrees, and so follow the inheritance of racial differences through successive generations. We shall never have an adequate knowledge of human racial inheritance until this has been done on a large scale with crosses between different races in various parts of the world.

This paper contains an account of observations on inter-racial crosses between whites and Indians in Canada. A single pedigree with various interlacing branches has been followed, and the evidence concerning the inheritance especially of skin colour and eye colour has been made as complete as the circumstances would permit…

This paper is in one aspect a study of the later stages of absorption of a race surviving in small numbers in a more numerous population of another race. In that respect it resembles the study of a small Negro element being partly absorbed into a Caucasian population in Canada (Gates 1953a). But in the present case the miscegenation of the Indians in Cuba has been first with the Spaniards and more recently with Negroes. It shows that the absorption of small numbers of one race in another requires many centuries before it is complete. The history of the Basques in Western France and Northern Spain shows that, even where the physical differences are of a very minor character, the differences in customs and in location will lead to the persistence of a race within a larger population for many millenia. The physical differences, where they exist, will persist indefinitely, long after the cultural differences have disappeared.

It has frequently been stated that the Indians of Cuba were exterminated by A.D. 1600, but this is not strictly true. Pichardo Moya (1945), who gives a full bibliography of Cuban history and archeology, quotes Morrell, who wrote before 1760, that traces of the last Indians still existed in the vicinity of Bayamo, Canéy and Jiguaní, possibly in Pinar del Río, around Alquízar, and certainly in Oriente. Pichardo…
