The evolution of morphological diversity
TL;DR: Quantitative morphological studies reveal profound changes in evolutionary rates corresponding with the generation of morphological disparity at low taxonomic diversity during the early radiation of many clades.

Abstract: The diversity of organismic form has evolved nonuniformly during the history of life. Quantitative morphological studies reveal profound changes in evolutionary rates corresponding with the generation of morphological disparity at low taxonomic diversity during the early radiation of many clades. These studies have also given insight into the relative importance of genomic and ecological factors in macroevolution, the selectivity of extinction, and other issues. Important progress has been made in the development of morphological spaces that can accommodate highly disparate forms, although this area still needs more attention. Other future directions include the relationship between morphological and ecological diversification, geographic patterns in morphological diversity, and the role of morphological disparity as a causal factor in macroevolution.

A trait-based test for habitat filtering: convex hull volume
TL;DR: Convex hull volume, a construct from computational geometry, is presented, which provides an n-dimensional measure of the volume of trait space occupied by species in a community, and it is shown that observed plant communities occupy less trait space than expected from random assembly, a result consistent with habitat filtering.

TL;DR: In the six decades since the publication of Huxley's Evolution: The Modern Synthesis, the spectacular empirical advances in the biological sciences have been accompanied by equally significant developments within the core theoretical framework of the discipline.

Stromatolites in precambrian carbonates : evolutionary mileposts or environmental dipsticks ?
TL;DR: Application of a process-based approach has shown that stromatolites were originally formed largely through in situ precipitation of laminae during Archean and older Proterozoic times, but that younger ProTerozoic strom atolites grew largely through the accretion of carbonate sediments, most likely through the physical process of microbial trapping and binding.

Morphological variation and width of ecological niche
TL;DR: These and other results suggest that continuous variation within local populations is often adaptive in itself and is not part of the genetic or phenotypic load.

A kinetic model of Phanerozoic taxonomic diversity; III, Post-Paleozoic families and mass extinctions
TL;DR: The good fit of this model to data on Phanerozoic familial diversity suggests that many of the large-scale patterns of diversification seen in the marine fossil record of animal families are simple consequences of nonlinear interrelationships among a small number of parameters that are intrinsic to the evolutionary faunas and are largely (but not completely) invariant through time.

Geometric analysis of shell coiling; general problems
TL;DR: In this article, the spectrum of possible shell forms is shown by a block diagram, where functional and evolutionary groups are confined to discrete regions of the spectrum and three parameters are considered at a time.
