Phylogeny01:23

Phylogeny

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...
Anatomical Terminology01:20

Anatomical Terminology

Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

Phylogenetic Trees03:21

Phylogenetic Trees

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.The length of the branches can depict time or the relative amount of change among organisms. For instance, the branch length might indicate the number of amino acid changes in the sequence that underlies the...

Evolutionary Relationships through Genome Comparisons02:54

Evolutionary Relationships through Genome Comparisons

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...

Area of Science:

  • Biomedical Informatics
  • Developmental Biology
  • Ontology Engineering

Background:

  • The Open Biomedical Ontologies (OBO) library aims to standardize biomedical ontologies.
  • Accurate representation of relations like "derives_from" is crucial for biomedical informatics.
  • Ontogenetic processes involve transformations where one entity originates from another.

Purpose of the Study:

  • To critically examine the treatment of the "derives_from" relation within the OBO Relation Ontology.
  • To assess the conformity of the OBO Relation Ontology's "derives_from" relation to biological and medical reality.
  • To optimize the representation of developmental relationships in biomedical informatics.

Main Methods:

  • Critical analysis of the "derives_from" relation in the OBO Relation Ontology.
  • Evaluation of the ontology's alignment with real-world ontogenetic processes.
  • Review of existing literature on relations in biomedical informatics.

Main Results:

  • The "derives_from" relation is fundamental in understanding embryology and ontogeny.
  • Current OBO treatment of "derives_from" may not fully capture the nuances of biological development.
  • Potential discrepancies exist between the ontology's relational model and biological reality.

Conclusions:

  • The OBO Relation Ontology's handling of "derives_from" requires critical assessment for improved accuracy.
  • Ensuring ontological relations reflect biological processes is vital for advancing biomedical informatics.
  • Further refinement of the "derives_from" relation is necessary for robust ontogenetic modeling.
