1. The role of natural selection in human evolution – insights from Latin America
Abstract A brief introduction considering Darwin's work, the evolutionary synthesis, and the scientific biological field around the 1970s and subsequently, with the molecular revolution, was followed by selected examples of recent investigations dealing with the selection-drift controversy. The studies surveyed included the comparison between essential genes

2. Immunodetection of Helicobacter sp. and the associated expression of ABO blood group antigens in the gastric mucosa of captive and free-living New World primates in the Amazon region
The histo-blood group ABH antigens were first described in humans. These antigens are only present on erythrocytes from great apes and humans, while in more primitive animals they are found in tissues and body fluids. The ABH antigens are mainly distributed in tissues exposed to the external environment and potentially serve as ligands for pathogens or inhib

3. A personalidade jurídica dos grandes primatas / The great apes legal personhood
A lei atual foi forjada sobre a premissa de que a humanidade está no centro do mundo e de que o homem é o único e legitimado senhor de todos os seres vivos. Desde que Darwin revelou para o mundo uma então chocante realidade sim, nós viemos de um símio ancestral os princípios filosóficos do antropocentrismo começaram a ruir. E os animais, que nós se

4. Syntenic homology of human unique DNA sequences within chromossome regions 5q31, 10q22, 13q32-33 and 19q13.1 in the great apes
Homologias entre os padrões de bandamento de cromossomos e seqüências de DNA em grandes macacos e humanos sugerem uma aparente origem comum para estas duas linhagens. A disponibilidade de sondas de DNA para regiões específicas de cromossomos humanos (5q31, 10q22, 13q32-33 e 19q13.1) nos levou a realizar hibridação cruzada com cromossomos de chimpanzé

5. The evolution of primate visual self-recognition: evidence of absence in lesser apes
Mirror self-recognition typically emerges in human children in the second year of life and has been documented in great apes. In contrast to monkeys, humans and great apes can use mirrors to inspect unusual marks on their body that cannot be seen directly. Here we show that lesser apes (family Hylobatidae) fail to use the mirror to find surreptitiously place

6. Higher rate of evolution of X chromosome alpha-repeat DNA in human than in the great apes.
The rate of introduction of neutral mutations is lower in man than in other primates, including the chimpanzee. This species is generally regarded as our closest relative among the great apes. We present here an analysis of sequences of X chromosomal alphoid repetitive DNA from man and the great apes, which supports the closer relationship between man and ch

7. A young Alu subfamily amplified independently in human and African great apes lineages.
A variety of Alu subfamilies amplified in primate genomes at different evolutionary time periods. Alu Sb2 belongs to a group of young subfamilies with a characteristic two-nucleotide deletion at positions 65/66. It consists of repeats having a 7-nucleotide duplication of a sequence segment involving positions 246 through 252. The presence of Sb2 inserts was

8. Mirror self-recognition in the bottlenose dolphin: A case of cognitive convergence
The ability to recognize oneself in a mirror is an exceedingly rare capacity in the animal kingdom. To date, only humans and great apes have shown convincing evidence of mirror self-recognition. Two dolphins were exposed to reflective surfaces, and both demonstrated responses consistent with the use of the mirror to investigate marked parts of the body.

9. The dietary adaptations of European Miocene catarrhines.
European Miocene "apes" have been known for nearly a century and a half but their phylogenetic significance is only now becoming apparent with the recent discovery of many relatively complete remains. Some appear to be close in time and morphology to the last common ancestor of modern great apes and humans. The current study is an attempt to reconstruct the

10. Comparative Analysis of Gene-Expression Patterns in Human and African Great Ape Cultured Fibroblasts
Although much is known about genetic variation in human and African great ape (chimpanzee, bonobo, and gorilla) genomes, substantially less is known about variation in gene-expression profiles within and among these species. This information is necessary for defining transcriptional regulatory networks that contribute to complex phenotypes unique to huma

11. Reconstruction of genomic rearrangements in great apes and gibbons by chromosome painting.
The homology between hylobatid chromosomes and other primates has long remained elusive. We used chromosomal in situ suppression hybridization of all human chromosome-specific DNA libraries to "paint" the chromosomes of primates and establish homologies between the human, great ape (chimpanzee, gorilla, and orangutan), and gibbon karyotypes (Hylobates lar sp

12. Emergence of the keratinocyte growth factor multigene family during the great ape radiation.
The structural gene for human keratinocyte growth factor (KGF), a member of the fibroblast growth factor family, consists of three coding exons and two introns typical of other fibroblast growth factor loci. A portion of the KGF gene, located on chromosome 15, is amplified to approximately 16 copies in the human genome, and these highly related copies (which
