Phylogenetic Trees

41.6K
Phylogenetic trees come in many forms. It matters in which sequence the organisms are arranged from the bottom to the top of the tree, but the branches can rotate at their nodes without altering the information. The lines connecting individual nodes can be straight, angled, or even curved.

Survival Tree

498
Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Evolutionary Relationships through Genome Comparisons

5.8K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Microbial Phylogeny

88
Understanding the evolutionary relationships among microorganisms is fundamental to microbial ecology and taxonomy. Phylogenetic trees are essential tools for inferring these relationships, relying primarily on comparative analyses of molecular sequences such as DNA, RNA, or proteins. In microbial studies, these trees typically depict the evolutionary paths of diverse bacterial and archaeal species by mapping genetic differences accumulated over time.Phylogenetic trees are composed of tips,...

Phylogeny01:23

Phylogeny

47.2K
Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.

Area of Science:

  • Phylogenetics
  • Computational Biology
  • Evolutionary Biology

Background:

  • Supertrees integrate diverse, overlapping phylogenetic trees to provide a high-level synthesis.
  • They serve as meta-analytical tools, enhancing statistical power for evolutionary trend studies.
  • Supertrees are crucial in phylogenomics for combining gene trees and inferring species phylogenies.

Purpose of the Study:

  • Introduce the L.U.St package, a Python tool for approximate maximum likelihood supertree inference.
  • Demonstrate L.U.St's application using a genomic dataset of placental mammals.
  • Provide a novel, fully parametric supertree method with clear properties and advantages.

Main Methods:

  • L.U.St calculates approximate supertree likelihoods from input trees.
  • It employs heuristic searches to identify the highest likelihood supertree.
  • Includes a winning sites test for ranking hypotheses and outputs likelihood scores for standard tree tests.

Main Results:

  • The L.U.St package enables approximate maximum likelihood supertree inference.
  • It facilitates statistical testing of supertree hypotheses.
  • Demonstrated utility with a genomic dataset for placental mammals.

Conclusions:

  • L.U.St is the first fully parametric supertree implementation.
