Several captive chimpanzees and bonobos have learned to use symbols and to comprehend syntax. Thus, compared with other nonhumans, these animals appear to have unusual cognitive powers that can be recruited for communicative behavior. This raises the possibility that wild chimpanzee vocal communication is more complex than heretofore demonstrated. To examine this possibility, I investigated whe...

Induced pluripotent stem cells (iPSCs) are potentially valuable cell sources for disease models and future therapeutic applications; however, inefficient generation and the presence of integrated transgenes remain as problems limiting their current use. Here, we developed a new Sendai virus vector, TS12KOS, which has improved efficiency, does not integrate into the cellular DNA, and can be easi...

Here we present a draft genome sequence of the common chimpanzee (Pan troglodytes). Through comparison with the human genome, we have generated a largely complete catalogue of the genetic differences that have accumulated since the human and chimpanzee species diverged from our common ancestor, constituting approximately thirty-five million single-nucleotide changes, five million insertion/dele...

The human and nonhuman primate ABO blood group gene shows relatively large numbers of nucleotide differences around the exon 7 region. In this study we determined intron 6 sequences for 9 alleles of common chimpanzee and for 3 alleles of bonobo to estimate nucleotide diversities among them. Sequence length polymorphisms are observed in this region as a repeat appears one to five times. From a p...

The use of referent taxa, and especially chimpanzee referents, in modeling human evolution has been harshly criticized. No doubt, chimpanzee data are often misused in models of early hominid behavior. But, those misuses are examples of careless, formal analogizing. In contrast, it is equally possible to create non-trivial chimpanzee analogies. These analogies can, in turn, be linked together to...

The ability of a chimpanzee (Pan troglodytes) to recognize photographs of conspecifics was evaluated with heart-rate measures. Heart rate was recorded before, during, and after viewing photographs of an aggressive chimpanzee, a friendly companion animal, and an unfamiliar chimpanzee. The subject displayed a differential pattern of heart-rate response to the stimulus animals, without prior exper...

DNA sequences evolving differently in the human and chimpanzee genomes signal recent and regionally limited changes in the process of DNA sequence evolution. Here we present the comparison of 90 kb from the nonrecombining part of the human Y chromosome to the corresponding part of the chimpanzee genome using gorilla as out-group. Our results reveal a significant difference in the region-specifi...

Faces presented upside-down are harder to recognize than presented right-side up, an effect known as the face inversion effect. With inversion the perceptual processing of the spatial relationship among facial parts is disrupted. Previous literature indicates a face inversion effect in chimpanzees toward familiar and conspecific faces. Although these results are not inconsistent with findings f...

We have performed a fine-scale comparative study of the human and chimpanzee genomes, using linkage, linkage disequilibrium and sequence analyses on microsatellite loci spanning a region of approximately 30 cM on human chromosome 4p. Our results extend the findings of previous studies that indicated virtually complete conservation between the human and chimpanzee genomes at the chromosomal and ...
