Evolutionary Relationships through Genome Comparisons02:54

Evolutionary Relationships through Genome Comparisons

5.7K
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...

Phylogenetic Trees

45.3K
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.

Phylogeny01:23

Phylogeny

43.8K
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.

Survival Tree01:19

Survival Tree

78
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.

Gene Evolution - Fast or Slow?

7.1K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

The Tree of Life - Bacteria, Archaea, Eukaryotes

32.3K
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:

  • Computational Biology
  • Phylogenetics
  • Machine Learning

Background:

  • The Hybridization problem aims to create a single phylogenetic network from conflicting trees, minimizing reticulation nodes.
  • Existing solutions struggle with large or complex datasets, particularly multifurcating trees with differing taxon sets.

Purpose of the Study:

  • To present FHyNCH, the first algorithmic framework for heuristically solving the Hybridization problem on large, diverse phylogenetic tree datasets.
  • To extend previous work on binary trees to handle multifurcating trees with non-identical taxon sets.

Main Methods:

  • FHyNCH combines the cherry-picking technique with two novel machine-learning models.
  • The framework is designed to handle large sets of multifurcating trees with potentially different taxon sets.

Main Results:

  • FHyNCH demonstrates practical applicability for solving the Hybridization problem.
  • The methods produce qualitatively good solutions for phylogenetic network construction.

Conclusions:

  • FHyNCH offers a significant advancement in computationally reconciling complex phylogenetic data.
  • This framework enables more accurate and scalable phylogenetic network inference for diverse biological datasets.
