Homogamy and imprinting-like effect on mate choice preference for body height in the current Japanese population
This study shows that homogamy for body height is present in the current Japanese population and that it may in part result from an individual's preference. It also indicates a possible role of a sexual imprinting-like mechanism in human mate choice

Sexual selection as a cause of human skin colour variation: Darwin's hypothesis revisited
The dark skin of tropical peoples is likely to be an adaptation to the strong ultraviolet (UV) radiation near the equator, perhaps protecting against sunburn or degradation of folate. By contrast, the adaptive value of light skin is questionable. In particular, the relevance of vitamin D deficiency rickets as a selective factor has been cogently criticized. Population genetic studies on the melanocortin 1 receptor (MC1R) gene (one of the genes re…

Hanihara's Conundrum Revisited. Theoretical Estimates of the Immigration into Japan during the 1,000 Year Period from 300 B.C. to A.D. 700
Prehistoric Japanese population is believed to have increased from 75, 800 in 300 B.C. to 5, 399, 800 in A.D. 700-a 70-fold increase in 1, 000 years. The rate of natural increase-hereafter called the annual growth rate-likely averaged 0.1% during this period. A closed population growing at this rate would have experienced only a 2.7-fold increase, so that the deficit must have been balanced by immigration, and the question is how much? Hanihara (…
HLA and Human Mate Choice. Tests on Japanese Couples
House mice are apparently more likely to mate with individuals dissimilar to themselves at MHC (major histocompatibility complex) loci than with similar individuals. Such negative assortative mating is thought to be mediated by olfaction. Recently, it has been suggested that huma mate choice may be affected by HLA (human leukocyte antigen; MHC in humans), based on the finding that women prefer the odor of men dissimilar to themselves at HLA loci …
Transmission of Tool-making through Verbal and Non-verbal Communication: Preliminary Experiments in Levallois Flake Production
We describe a series of preliminary experiments undertaken to investi-gate the relationship between complicated tool-making and the presence or absence of language in its communicative role. The experiments involved teaching two groups of university students how to make Levallois flakes by either verbal or non-verbal demonstration. The rates and mean times of acquisition of the Levallois technique and of successful flake production were compared.…
Individual Versus Social Learning: Evolutionary Analysis in a Fluctuating Environment
A model for haploid asexual inheritance of social and individual learning is proposed. Animals of one genotype, individual learners (IL), behave optimally for the current environment and, except for a fixed cost due to learning errors, have the optimal fitness in that environment. Animals of the other genotype are social learners (SL) each of whom copies a random individual from the previous generation. However, the phenotype of a social learner …
Maximum Likelihood Fit of a Gradual Admixture Model to Clines of Gene Frequencies in the Main Islands of Japan
The hypothesis was tested that the observed clines of gene frequencies in the main islands of Japan (Kyushu, Shikoku, and Honshu) were produced by a two-phase episode of immigration and admixture. In the first phase, an intrusive population occupies the western part of the main islands, causing a temporary discontinuity in the geographical distribution of the gene frequency at each locus. In the second phase, gradual admixture occurs by the rando…
Modelling the Dispersal of the First Americans through an Inhospitable Ice-free Corridor
An ice-free corridor is believed to have existed during the late Pleistocene, but it is suspected that ecological conditions may have been severe. Hence, it is controversial whether the route could have been used by the first Americans in their southward expansion from Beringia to the interior of North America. Two demographic models, both assuming negative population growth in the corridor, are examined to evaluate the possibility of a successfu…
Some Theoretical Aspects of the Origin of Cultural Transmission
Average coefficient of relationship within troops of the Japanese monkey and other primate species with reference to the possibility of group selection
An Analysis of the ABO Gene Frequency Cline in Japan: A Migration Model
The well known cline in ABO blood group gene frequencies in Japan was analysed based on the working hypothesis of a transient cline formed by the admixture of two heterogeneous populations by diffusion.Mathematically, the model corresponds to solving the diffusion equation with a step function as the initial condition. Using the A allele frequency data, the position of the initial discontinuity in the gene frequency is estimated by simulation as …
