Phylogeny01:23

Phylogeny

55.9K
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.

Phylogenetic Trees03:21

Phylogenetic Trees

48.7K
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.

Evolutionary Relationships through Genome Comparisons02:54

Evolutionary Relationships through Genome Comparisons

6.6K
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...

Modern Molecular Taxonomy

Advancements in molecular biology have revolutionized the identification and characterization of bacteria, with multiple methods leveraging DNA sequencing for enhanced precision. As sequencing technologies improve and costs decline, these approaches are increasingly used in clinical, environmental, and evolutionary studies.Multilocus Sequence Typing (MLST) examines several housekeeping genes, essential chromosomal genes encoding cellular functions, to distinguish strains. Approximately...

The Tree of Life - Bacteria, Archaea, Eukaryotes02:40

The Tree of Life - Bacteria, Archaea, Eukaryotes

36.8K
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...

Diversity of Protists IV01:27

Diversity of Protists IV

567
Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...

Area of Science:

  • Botany
  • Evolutionary Biology
  • Genomics

Background:

  • The Calamoideae subfamily represents over 20% of palm species (Arecaceae) and is vital for rattan production.
  • Phylogenetic relationships within Calamoideae are crucial for understanding palm evolution and diversity but remain poorly understood.
  • Existing knowledge gaps hinder comprehensive taxonomic, systematic, and macroevolutionary research.

Purpose of the Study:

  • To reconstruct a well-supported phylogeny for the Calamoideae subfamily.
  • To clarify higher-level phylogenetic relationships within the subfamily.
  • To provide a robust framework for future evolutionary and biodiversity studies.

Main Methods:

  • Sequencing of nearly 1000 nuclear genomic regions.
  • Phylogenomic analyses of 75 systematically selected Calamoideae species.
  • Analysis of taxonomic diversity across all calamoid genera.

Main Results:

  • A maximally supported phylogenetic backbone for the Calamoideae was resolved.
  • Several previously un-inferred higher-level relationships were identified.
  • Low gene tree conflict was observed for the backbone, with complex histories in some subtribes.

Conclusions:

  • The study provides a robust phylogenomic framework for Calamoideae evolution.
  • This framework will facilitate future research in taxonomy, systematics, biogeography, and macroevolution.
  • New insights into the evolutionary history of palms have been generated.
