Survivorship biases can generate remarkable apparent rate heterogeneities through time in
otherwise homogeneous birth-death models of phylogenies. They are a potential …

Studies of biodiversity through deep time have been a staple for biologists and
paleontologists for over 60 years. Investigations of species richness (diversity) revealed that …

Despite being the objects of numerous macroevolutionary studies, many of the best
represented constituents of the fossil record—including diverse examples such as …

Phenotypic variation is fundamental to evolutionary change. Variation not only evinces the
connectivity of populations but it is also associated with the adaptability and evolvability of …

Lineage persistence is as central to biology as evolutionary change. Important questions
regarding persistence include: why do some lineages outlive their relatives, neither …

In a recent review, Vaux, Trewick & Morgan-Richards (2016) argued that species are
'arbitrary', speciation virtually unstudyable (especially in the fossil record), and that the terms …

It is increasingly recognised that cultural transmission involves inheritance, variation of
practice and the differential representation of particular variants in subsequent generations …
