The Importance of Fossils in Phylogeny Reconstruction
نویسندگان
چکیده
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 of great use in clarifying relationships and that conclusions are necessarily tenuous in their absence. Thus, Thorne (58, p. 85) commented 431 0066-4170/90/0101/0431 $02.00 Annual Reviews www.annualreviews.org/aronline

Phylogeny, paleontology, and primates: do incomplete fossils bias the tree of life?
Paleontological systematics relies heavily on morphological data that have undergone decay and fossilization. Here, we apply a heuristic means to assess how a fossil's incompleteness detracts from inferring its phylogenetic relationships. We compiled a phylogenetic matrix for primates and simulated the extinction of living species by deleting an extant taxon's molecular data and keeping only th...
متن کاملProblematica old and new.
Problematica are taxa that defy robust phylogenetic placement. Traditionally the term was restricted to fossil forms, but it is clear that extant taxa may be just as difficult to place, whether using morphological or molecular (nucleotide, gene or genomic) markers for phylogeny reconstruction. We discuss the kinds and causes of Problematica within the Metazoa, as well as criteria for their reco...
متن کاملPhylogenetic relationships of the commercial marine shrimp family Penaeidae from Persian Gulf
Phylogenetic relationships among all described species (total of 5 taxa) of the shrimp genus Penaeus, were examined with nucleotide sequence data from portions of mitochondrial gene and cytochrome oxidase subunit I (COI). There are twelve commercial shrimp in the Iranian coastal waters. The reconstruction of the evolution phylogeny of these species is crucial in revealing stock identity that ca...

متن کاملSedimentary Facies, Architectural Elements and Trace Fossils of Kashkan Formation, Folded Zagros Zone in SW Iran
The Kashkan Formation (Paleocene to Middle Eocene), consists of conglomerate, sandstone, and siltstone in the Zagros Folded zone, southwest Iran. Type of the sedimentary facies, architectural elements and trace fossils show that Kashkan deposits were formed in a low sinuosity braided stream system, with north to south flow direction. The formation displays coarsening-upward succession reflects ...
