African populations and the evolution of human mitochondrial DNA.
TLDR
The African origin hypothesis of human mtDNA evolution is supported by two statistical tests and two hypervariable segments of mtDNA were sequenced from 189 people of diverse geographic origin, including 121 native Africans. Expand
Genetic analyses from ancient DNA.
TLDR
The precautions and criteria necessary to ascertain to the greatest extent possible that results represent authentic ancient DNA sequences are discussed, which highlight some significant results and areas of promising future research. Expand
Quantitative polymerase chain reaction analysis of DNA from noninvasive samples for accurate microsatellite genotyping of wild chimpanzees (Pan troglodytes verus)
TLDR
An assay designed to measure the amount of amplifiable nuclear DNA in low DNA concentration extracts from noninvasive samples is described and a new efficient approach for accurate microsatellite genotyping is formulated. Expand
Mitochondrial DNA sequences in single hairs from a southern African population.
TLDR
Evidence of geographic structuring of the mitochondrial diversity in Africa, together with knowledge of the rate of accumulation of base changes in human mtDNA, implies that the average rate at which female lineages have moved their home bases during hunter-gatherer times could be as low as 13 meters per year. Expand
Factors affecting the amount of genomic DNA extracted from ape faeces and the identification of an improved sample storage method
TLDR
There was a small negative correlation between temperature at time of collection and the amount of DNA obtained, but significantly higher amounts of DNA were obtained using a novel protocol that combines a short period of storage in ethanol with subsequent desiccation using silica. Expand
Generation times in wild chimpanzees and gorillas suggest earlier divergence times in great ape and human evolution
TLDR
The human–chimpanzee split is dated to at least 7–8 million years and the population split between Neanderthals and modern humans to 400,000–800,000 y ago, which suggests that molecular divergence dates may not be in conflict with the attribution of 6- to 7-million-y-old fossils to the human lineage and 400,,000-Y-old bones to the Neanderthal lineage.

Social Bonds Enhance Reproductive Success in Male Macaques
TLDR
It is found that strong bonds were linked to coalition formation, which in turn predicted future social dominance, which influenced paternity success and the strength of males' social bonds was directly linked to the number of offspring they sired. Expand
Genetic analysis reveals population structure and recent migration within the highly fragmented range of the Cross River gorilla (Gorilla gorilla diehli)
TLDR
Investigation of population structure in the critically endangered Cross River gorilla is investigated by applying a suite of individual‐based analyses to data obtained from between one‐quarter and one‐third of the estimated total population through the use of noninvasively collected DNA samples, suggesting persistent recent reproductive contact between many of the localities. Expand
Insights into hominid evolution from the gorilla genome sequence
TLDR
A comparison of protein coding genes reveals approximately 500 genes showing accelerated evolution on each of the gorilla, human and chimpanzee lineages, and evidence for parallel acceleration, particularly of genes involved in hearing. Expand
The limited impact of kinship on cooperation in wild chimpanzees
TLDR
It is shown that male chimpanzees clearly prefer to affiliate and cooperate with their maternal brothers in several behavioral contexts, adding to a growing body of research that indicates that animals cooperate with each other to obtain both direct and indirect fitness benefits and that complex cooperation can occur between kin and nonkin alike.
