TL;DR: The results show that in both the IAM and SMM CAVALLI-SFORZA and EDWARDS' chord distance (DC) and NEI et al.'s DA distance generally show higher PC values than other distance measures, whether the bottleneck effect exists or not.

TL;DR: To estimate approximate divergence times of species or species groups with molecular data, a method of constructing a linearized tree under the assumption of a molecular clock is developed and used to analyze hominoid mitochondrial DNA and drosophilid Adh gene sequences.

TL;DR: In POPTREE2 genetic distances, average heterozygosities and G(ST) are computed through a simple and intuitive Windows interface, which will facilitate statistical analyses of polymorphism data for researchers in many different fields.

TL;DR: The phylogenetic relationships and divergence times of 39 drosophilid species were studied by using the coding region of the Adh gene to show that Scaptomyza experienced a rapid morphological evolution and many of the D. repleta group species studied here have two functional Adh genes, and these duplicated genes can be explained by two duplication events.

TL;DR: The relative efficiencies of different protein-coding genes of the mitochondrial genome and different tree-building methods in recovering a known vertebrate phylogeny was evaluated, and the utility of the currently used optimization principles in phylogenetic construction is questioned.
