We present a complete phylogeny of macroperforate planktonic foraminifer species of the
Cenozoic Era (∼ 65 million years ago to present). The phylogeny is developed from a large …

Body size is a central feature of any organism, reflecting its physiology, ecology and
evolutionary history. Marine microplankton are major contributors to the particulate inorganic …

The world's most revered and eloquent interpreter of evolutionary ideas offers here a work of
explanatory force unprecedented in our time—a landmark publication, both for its historical …

In 1972 Stephen Jay Gould took the scientific world by storm with his paper on punctuated
equilibrium. Challenging a core assumption of Darwin's theory of evolution, it launched the …

The nature of evolutionary changes recorded by the fossil record has long been
controversial, with particular disagreement concerning the relative frequency of gradual …

Trends are the primary phenomenon of macroevolution, but they have often been
misinterpreted because an old and deep conceptual error has induced us to misread, as …

Nature's discontinuities occur both in the hierarchical structuring of genealogical individuals
and in the distinct processes operating at different scales of time, here called tiers …

Pelagic (open-ocean) species have enormous population sizes and broad, even global,
distributions. These characteristics should damp rates of speciation in allopatric and …

A general morphometric procedure is described that organizes collections of microfossil
outlines according to their shape. It involves representing the greatest proportion of variation …

Atlantic psychrospheric and temperate mesopelagic faunas found in the lower Messinian
marls in Morocco indicate that a strong, eastward flowing, bottom current was present in the …
