SummaryThe phylogeny of the major groups of tetrapods (amphibians, reptiles, birds, and mammals) has until recently been poorly understood. Cladistic analyses of morphological data are producing new hypotheses concerning the relationships of the major groups, with a focus on the identification of monophyletic groups. Molecular phylogenies support some of these views and dispute others. Geological dates of the major evolutionary branching points are recalculated on the basis of the cladograms… 

Molecular phylogeny of frogs (Amphibia: Anura) based on complete mitochondrial genomes and partial nuclear genes

A sequence data set combining complete mitochondrial genomes and nine nuclear loci was used to estimate a molecular phylogeny of frogs and tackle long-standing contentious questions, suggesting that the 5' end of the control region is a hot spot of gene rearrangement in frogs.

Recent Advances in the (Molecular) Phylogeny of Vertebrates

A discussion of limitations of currently used molecular markers and phylogenetic methods as well as the contribution of molecular phylogenetic data to their resolution are presented.

Higher-order phylogeny of modern birds (Theropoda, Aves: Neornithes) based on comparative anatomy. II. Analysis and discussion

A phylogenetic (cladistic) analysis of 150 taxa of Neornithes, including exemplars from all non-passeriform families, and subordinal representatives of Passeriformes, confirmed the topology among outgroup Theropoda and achieved robust resolution at virtually all levels of the NeornIthes.

Molecular Systetnatics of Atnphibians

Applications of Molecular Methods in Amphibian Systematics and Phylogenetics versus Population Genetics and Methods of Analysis of Molecular Data are presented.

A multilocus timescale for the origin of extant amphibians.

Initial Diversification of Living Amphibians Predated the Breakup of Pangaea

A robust molecular phylogeny based on the nuclear RAG1 gene as well as results from a variety of alternative independent molecular clock calibrations suggest that the origin and early divergence of the three living amphibian orders dates back to the Palaeozoic or early Mesozoic, before the breakup of Pangaea, and soon after the divergence from lobe‐finned fishes.

A Phylogenomic Approach to Vertebrate Phylogeny Supports a Turtle-Archosaur Affinity and a Possible Paraphyletic Lissamphibia

A novel statistical method is developed and tested that identifies sites that have a high probability of containing biased signal for a specific phylogenetic relationship, and support emerged for a sister relationship between turtles and either crocodilians or archosaurs, as well as for a caecilian-salamander sister relationship within Lissamphibia.

Origins, Diversity and Relationships of Lemurs

Overall, it now seems that primates originated at around 90 Ma rather than the 55 Ma indicated by direct reading of the known fossil record, and colonization of Madagascar by lemurs would have taken place at about 80 Ma, double the date usually accepted, and should be interpreted in terms of contemporary continental relationships.

Molecular phylogeny and divergence times of deuterostome animals.

It is found that most major lineages of deuterostomes arose prior to the Cambrian Explosion of fossils and that several lineages had originated before periods of global glaciation in the Precambrian.

Dating the Tree of Life

Intense study of the dating of major splits in the tree of mammals has shown rapprochement as fossil dates become older and molecular dates become younger.



Mammalian phylogeny: comparison of morphological and molecular results.

The morphological and molecular phylogenies agree in depicting the infraclass Eutheria as consisting of five major clades (thus resolving part of the "bush").

The higher-level systematics of the mammalian infraclass Eutheria is investigated with protein sequences of seven polypeptide types combined in an extended tandem alignment. Evolutionary trees

Molecules and Morphology in Evolution: Conflict or Compromise?

The phylogeny of hominoid phylogeny revealed by coevolution of molecules and morphologies in vertebrate phylogeny is reconstructed from comparisons of the genetic material, DNA and morphological data.


Comparison morphology and paleontology offer some compelling hypotheses that comprise a framework for studies of macromolecular traits that support groupings of the Recent orders of eutherian mammals.

The relationships of mammals

It is argued that the current views are variously based on an overemphasis of superficial dental similarities, misinterpretation of the structure of the mammalian braincase, and too ready acceptance of parallel evolution amongst the groups concerned.


The fossil record of early amniotes is complete enough to establish their relationships to the major groups living today and provides an opportunity to consider the evolutionary processes associated with a period of major radiation.


The importance of the critical fossils seems to reside in their relative primitive‐ness, and the simplest explanation for their more conservative nature is that they have had less time to evolve.

The classification of the Lepidosauria

  • S. Evans
  • Environmental Science, Geography
  • 1984
A new hypothesis of lepidosaurian relationships based on phylogenetic analysis is presented, and a new definition of the Lepidosauria is offered based on derived character states, which suggests squamates, sphenodontids and Gephyrosaurus are lepidosaurs; kuehneosaurs and younginiforms are not.

Evolution and the fossil record: patterns, rates, and processes

Mammals have an unusually good Cenozoic fossil record providing evidence of their evolutionary diversification, and Morphological innovation and taxonomic diversification appear following intervals of climatic cooling, suggesting that major features of evolution are extrinsically controlled.
