Phylogenetic Trees

51.8K
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.

Phylogeny

64.5K
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.

Microbial Phylogeny

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,...

Evolutionary Relationships through Genome Comparisons

7.2K
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...

The Tree of Life - Bacteria, Archaea, Eukaryotes

41.7K
The “tree of life” describes the evolution of life and the evolutionary relationships between organisms. The root of the tree is the common ancestor to all life on Earth. All other species radiate from this point, much like the branches of a tree. The numerous tips of these branches on the tree of life represent every living, or extant, species. Extinct species, which are species that no longer exist, can be found towards the center of the tree. Currently, these organisms, both...

Area of Science:

  • Evolutionary biology
  • Genetics
  • Epidemiology
  • Computational biology

Background:

  • Phylogenetic trees are crucial for visualizing evolutionary and genetic relationships across various scientific disciplines.
  • The complexity and data density of phylogenetic trees pose challenges for digital interaction and publication rendering.
  • Existing tools often lack intuitive navigation and annotation features for interactive tree exploration.

Purpose of the Study:

  • To introduce PhyloPen, an experimental multi-touch and pen application designed for interactive phylogenetic tree visualization and annotation.
  • To address the limitations of current methods in rendering and interacting with complex phylogenetic data.
  • To facilitate collaborative analysis and note-taking directly on phylogenetic trees.

Main Methods:

  • Development of PhyloPen, a novel application featuring multi-touch and pen-based interactions.
  • Implementation of interactive navigation for nodes, branches, and associated data within phylogenetic trees.
  • Conducting a formative study with practicing biologists (faculty and graduate students) to evaluate user reception.

Main Results:

  • PhyloPen enables users to interactively navigate and examine detailed information within phylogenetic trees.
  • The application supports annotation functionalities for note-taking and collaborative purposes.
  • A formative study indicated positive reception of PhyloPen by practicing biologists, providing insights for future development.

Conclusions:

  • PhyloPen offers a promising solution for overcoming challenges in visualizing and interacting with phylogenetic trees.
  • The application has the potential to enhance research in evolutionary biology, epidemiology, and other fields reliant on phylogenetic analysis.
  • User feedback from the formative study will guide the future development of a fully supported, community-driven implementation.
