Abstract Advantages of phylogenetic trees the last century, Darwin and Haeckel were the first to propose the phylogenetic trees. The first phylogenies were made intuitively, but in the fifties several researchers tried to propose rules for their reconstruction. The evolutionary school in tended to use the principies of evolution, the numerical or pheneticist school advanced the "distance methods", while the cladistic school proposed the "parsimony method".

The parsimony method tries to find the tree that requires the smallest number of changes. There are other methods that take in to account the evolutionary forces, like the maximum likelihood Felsenstein, In this paper we discuss some of the what does genetic effects of radiation mean associated to advantages of phylogenetic trees reconstruction, the advantages of the different methods and of some of the computer available programs, and finally we offer a perspective on the uses of the phylogenies.

Flanking regions of monomorphic microsatellite loci provide a new source of data for plant species-level phylogenetics. There are other methods that take in to account the evolutionary forces, like the maximum likelihood Felsenstein, It is not always clear what might emerge from the accretion of data over the long term; sometimes the focus evolves as the study progresses. Unlike the common genic approach to marker development, we generated DNA sequences of monomorphic nuclear microsatellite flanking regions in a phylogenetic study of Annona species Annonaceae. The parsimony method tries to find the tree that requires the smallest number of changes. The neutral evolution and high variability of flanking regions, together with the wide availability of monomorphic microsatellite loci in angiosperms, are useful qualities for species-level phylogenetics.

Unfortunately, there is also a taboo concerning consensus methods, because most biologists see them advantages of phylogenetic trees as comparators and not as phylogenetic tree constructors. We show that the GRF distance phylovenetic a very high what is the role of history, it can also be computed in linear time, and it is not uniformly equivalent to the RF distance. Potential pitfalls have also been revealed and include difficulties of inferring positional homology, incongruence between organismal and gene genealogies, and low likelihood of recovering the correct phylogeny given certain patterns in the timing of speciation events.
