Phylogeny01:23

Phylogeny

63.6K
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.

Evolutionary Relationships through Genome Comparisons

7.1K
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

50.4K
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.

Synteny and Evolution02:31

Synteny and Evolution

3.9K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
Around 80 million years ago, the human and mice lineages diverged from the common ancestor. During the course of evolution, the ancestral...

Gene Evolution - Fast or Slow?

8.3K
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...

Resumen

Este estudio introduce axiomas para definir especies basados en relaciones genealógicas, proponiendo el "axioma del punto ancestro idéntico" para reducir la subjetividad de las especies. Este trabajo tiene como objetivo definir restricciones biológicamente plausibles para clústeres máximos similares a especies.

Área de la Ciencia:

  • Biología Evolutiva
  • Biología Teórica
  • Filogenética

Sus antecedentes:

  • Definir especies es complejo y a menudo se basa en criterios subjetivos.
  • Las relaciones genealógicas ofrecen una base objetiva potencial para la delimitación de especies.
  • Los modelos existentes pueden no capturar completamente los matices de la formación y persistencia de especies.

Objetivo del estudio:

  • Introducir y formalizar axiomas para definir especies basados en relaciones genealógicas.
  • Proponer el "axioma del punto ancestro idéntico" como un principio clave para reducir la subjetividad de las especies.
  • Identificar restricciones biológicamente plausibles para definir clústeres máximos similares a especies.

Principales métodos:

  • Desarrollo de varios axiomas para analizar subgrafos del grafo genealógico del organismo.
  • Introducción del "axioma del punto ancestro idéntico" y un "axioma de convexidad".
  • Análisis matemático para demostrar cómo estos axiomas reducen la subjetividad de las especies y definen "clústeres similares a especies".
  • Conclusiones: Los axiomas formalizados proporcionan un marco riguroso para la definición de especies basado en la ascendencia.
  • El "axioma del punto ancestro idéntico" es crucial para la delimitación objetiva de especies.
  • Las restricciones identificadas ofrecen un camino para definir límites objetivos de especies dentro de un marco genealógico.

Principales resultados:

  • Los axiomas propuestos, en particular el "axioma del punto ancestro idéntico" con convexidad, reducen técnicamente la subjetividad de las especies.
  • Se introduce el concepto de "clústeres similares a especies" como conjuntos que satisfacen estos axiomas.
  • Se identifica un conjunto de dos restricciones biológicamente plausibles que garantizan que los organismos habiten en clústeres máximos similares a especies.
