Fossils and plant phylogeny.
Developing a detailed estimate of plant phylogeny is the key first step toward a more sophisticated and particularized understanding of plant evolution. At many levels in the hierarchy of plant life, it will be impossible to develop an adequate understanding of plant phylogeny without taking into account the additional diversity provided by fossil plants. This is especially the case for relativ...
متن کاملWhy coelacanths are not 'living fossils': a review of molecular and morphological data.
A series of recent studies on extant coelacanths has emphasised the slow rate of molecular and morphological evolution in these species. These studies were based on the assumption that a coelacanth is a 'living fossil' that has shown little morphological change since the Devonian, and they proposed a causal link between low molecular evolutionary rate and morphological stasis. Here, we have exa...
متن کاملFossils, Phylogeny, and Form: An Analytical Approach
In the eleven years since Harvey and Pagel (1991), evolutionary biologists committed considerable methodological effort into the relationship between phylogeny and numerous types of patterns. Morphology , Shape and Phylogeny and Fossils, Phylogeny, and Form both concern themselves with these issues. The former book deals primarily with the relationship between phylogeny and continuous mor-phome...
متن کاملThe Importance of Fossils in Phylogeny Reconstruction
It is widely believed that fossils are of fundamental importance in reconstructing phylogeny (e.g. 24, 28). Simpson (52, p. 83), for example, argued "fossils provide tl?,e soundest basis for evolutionary classification." Although phylogenies of many groups have been reconstructed using morphological or chemical characters of extant organisms alone, it is often noted that fossils would have been...
