ABSTRACT: The discovery of Paranthropus deyiremeda in 3.3–3.5 million year old fossil sites in Afar, together with 30% of the gorilla genome showing lineage sorting between humans and chimpanzees, and a NUMT (“nuclear mitochondrial DNA segment”) on chromosome 5...

ABSTRACT: The Gorilla Genome Project (Scally, 2012) showed that 30% of the gorilla genome introgressed into the ancestor of humans and chimpanzees, and that the two species diverged through lineage sorting with 15% ending up in Pan and another 15% in Homo. That...

The use of personal ornaments by Neandertals is one of the scarce evidence of their symbolic behaviour. Among them stand up the eagle talons used presumably as pendants, in an analogous way than anatomically Modern Humans (Homo sapiens) did. Considering the broad...

Tertiary dentine forms when an odontoblast is directly affected by stimuli, commonly through occlusal wear. In this study the presence of tertiary dentine is recorded in three South African fossil hominin species (Australopithecus africanus, Homo naledi and Paranthropus...

Primate individuals use a variety of strategies in intergroup encounters, from aggression to tolerance; however, recent focus on the evolution of either warfare or peace has come at the cost of characterizing this variability. Drawing on insights from across the...

Vervet monkeys (Chlorocebus pygerythrus) are one of the most widely distributed non-human primate species found in South Africa. They occur across all the South African provinces, inhabiting a large variety of habitats. These habitats vary sufficiently that it...

Sexual selection favors traits that increase mating and, thus, reproductive success. Some scholars have suggested that intrasexual selection driven by contest competition has shaped human male aggression. If this is the case, one testable hypothesis is that beliefs...

Almost a decade ago, the sequencing of ancient DNA from archaic humans - Neanderthals and Denisovans - revealed that modern and archaic humans interbred at least twice during the Pleistocene. The field of human paleogenomics has now turned its attention towards...

In vertebrates, it has been argued that the development and evolution of an enlarged brain requires an increased basal metabolic rate or a compensatory reduction in the resources devoted to the formation of other metabolically costly tissues, leading to a reduction...

Language and music are peculiar human behaviors. We spend a large portion of our lives speaking, reading, processing speech, performing music and listening to tunes. At the same time, we still know very little as to why and how these structured behaviors emerged...
