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 …

A great tradition in macroevolution and systematics has been the ritual squabbling between
palaeontologists and molecular biologists. But, because both sides were talking past each …

the behaviour and ecology of wild felids to draw together a unique network of the world's …

Plants have utterly transformed the planet, but testing hypotheses of causality requires a
reliable time‐scale for plant evolution. While clock methods have been extensively …

Large vertebrates are strong interactors in food webs, yet they were lost from most
ecosystems after the dispersal of modern humans from Africa and Eurasia. We call for …

Background Patterns of genetic and genomic variance are informative in inferring population
history for human, model species and endangered populations. Results Here the genome …

Calibration is the rate-determining step in every molecular clock analysis and, hence,
considerable effort has been expended in the development of approaches to distinguish …
