Diversity of Some Gene Frequencies in European and Asian Populations

Contemporary patterns of allele frequencies allow inferences on past evolutionary processes. L. L. CavalliSforza [(1988) Munibe 6, 129-137] and C. Renfrew [(1991) Cambridge Archaeol. J. 1, proposed that neolithic farmers from the Near East propagated a group of related ancestral languages, from which three or four linguistic families developed. Here we show that genetic variation among IndoEuropean, Elamo-Dravidian, and Altaic speakers (grouped by some linguists in the Nostratic macrofamily) supports this hypothesis, whereas the evidence on Afro-Asiatic speakers is ambiguous. Gene-frequency climes within these linguistic famiies suggest that language diffusion was largely associated with population movements rather than with purely cultural transmission. Archeological, linguistic, and genetic evidence can be reconciled by envisagng a process of population growth and multidirectional dispersal from the Near East as the main factor shaping genetic and liistic diversity in Eurasia and perhaps in North Africa.

“…On the other hand, no significant association has been observed in other populations (Hernandez et al, 1990), suggesting some effects of genetic background and/or environmental conditions. In this context, the observation of Farabegoli and Barbujani (1990) that the mean axis of the gradient for ACP1 alleles follows a NE-SW direction, paralleling the gradient observed for ADA locus, is of interest.…”

Adenosine deaminase-acid phosphatase association and the environment: A study in a continental Italian population

et al. 2000

Three hundred fifty newborns from Rome and 351 from Penne were studied in continental Italy. Medium high altitude above sea level and cold winters characterize the area of Penne, while low altitude and very mild winters characterize the area of Rome. An effect of environmental conditions on the association between adenosine deaminase (ADA) and acid phosphatase (ACP1), previously shown in Sardinia, has been confirmed in continental Italy. When compared with expected independent assortment, the proportion of ACP1*A/*A carrying the ADA*2 allele is lower than expected in the lowlands and higher than expected in highlands. In continental Italy there is an interaction among ACP1–ADA genotype, season of conception, and locality. The excess of *A/*A newborns carrying the ADA*2 allele is present only among those conceived in the first half of the year (January–June). Among newborns in Penne conceived in the Spring, the proportion of those with *A/*A genotype is increased and these infants show decreased intrauterine growth. The present data suggest that ADA and ACP1 interact during intrauterine life with effects on development and survival and that such effects are dependent on local environment and season of conception.

“…Autocorrelation coefficients were computed within five arbitrary distance classes (Table 3). In the literature, there are spatial autocorrelation analyses whose coefficients are computed in distance classes from 4 ( Barbujani and Pigliucci, 1989;Pigliucci and Barbujani, 1991) to higher numbers, such as 7 (Barbujani and Sokal, 1991), 10 (Epperson and Allard, 1989), 15 (Sokal et al, 1989a), and 24 (Farabegoli and Barbujani, 1990). The plot of autocorrelation coefficients vs. distance classes is a correlogram.…”

The internal mobility of the population of the province of Lecco (Lombardy, Italy) was evaluated on the basis of the frequency of characteristic surnames in three territorial areas as a function of their geographical distance. Nearly three fourths of the patterns are statistically significant in one of the three areas, where the process of diffusion of surnames could be interpreted as due to socioeconomic factors. On the contrary, a similar distribution is less evident in the other two areas of the same territory. Am. J. Hum. Biol. 11:305–315, 1999. © 1999 Wiley‐Liss, Inc.
