Tropical Africa is home to an astonishing biodiversity occurring in a variety of ecosystems.
Past climatic change and geological events have impacted the evolution and diversification …

The role of fossils in dating the tree of life has been misunderstood. Fossils can provide
good “minimum” age estimates for branches in the tree, but “maximum” constraints on those …

Previous analyses of relations, divergence times, and diversification patterns among extant
mammalian families have relied on supertree methods and local molecular clocks. We …

Six extant species of non-human great apes are currently recognized: Sumatran and
Bornean orangutans, eastern and western gorillas, and chimpanzees and bonobos [1] …

Comparative genomic analyses of primates offer considerable potential to define and
understand the processes that mold, shape, and transform the human genome. However …

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 …

Dating the tree of life is a core endeavor in evolutionary biology. Rates of evolution are
fundamental to nearly every evolutionary model and process. Rates need dates. There is …

Gene duplication is an important source of phenotypic change and adaptive evolution. We
leverage a haploid hydatidiform mole to identify highly identical sequences missing from the …

The search for the earliest fossil evidence of the human lineage has been concentrated in
East Africa. Here we report the discovery of six hominid specimens from Chad, central Africa …

The origins and the divergence times of the most basal lineages within primates have been
difficult to resolve mainly due to the incomplete sampling of early fossil taxa. The main …
