Intraspecific variation is abundant in all types of systematic characters but is rarely addressed in simulation studies of phylogenetic method performance. We compared the accuracy of 15 phylogenetic ...

Three distance methods including two hierarchical clustering methods [average linkage (UPGMA) and Neighbor Joining, NJ] and one non-hierarchical ordination method (Multidimensional Scaling, MDS) were ...

When species under a taxonomic umbrella have faced forks in the road, leading to extinction or adaptation, the path taken has been difficult to follow. Scientists now argue that long-used approaches ...

Just as bird watchers may use binoculars to add to their species lists, scientists interested in bird evolution may use computational tools to clarify avian lineages. Indeed, such tools have enabled ...

Biologists will be able to reconstruct the process of evolution, determine relationships between species and build phylogenetic trees with greater accuracy thanks to a new method for identifying ...

Female giant water bugs lay their eggs on a male's back after mating and the male takes care of the eggs until the nymphs are hatched, a couple of weeks later. A study led by Dr. Tomoya Suzuki of ...

Phylogenetic analysis explores the evolutionary relationships between organisms and is a vital foundation for microbial studies. The development of reliable phylogenetic trees is an important step in ...

Phylogeny is the representation of the evolutionary history and relationships between groups of organisms. The results are represented in a phylogenetic tree that provides a visual output of ...
