Evolutionary Relationships through Genome Comparisons

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...

Synteny and Evolution

Synteny and Evolution

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 chromosome underwent...

Modern Molecular Taxonomy

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...

Polytene Chromosomes

Polytene Chromosomes

Polytene chromosomes are giant interphase chromosomes with several DNA strands placed side by side. They were discovered in the year 1881 by Balbiani in salivary glands, intestine, muscles, malpighian tubules, and hypoderm of larvae Chironomus plumosus. Hence, these are also called "Salivary gland chromosomes." These are found in insects of the order Diptera and Collembola; in certain organs of mammals; and synergids, antipodes of flowering plants. Polytene chromosomes are also regularly...

Cis-regulatory Sequences

Cis-regulatory Sequences

Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Background:

Cetartiodactyla includes Artiodactyla (even-toed ungulates) and Cetacea (whales, dolphins, porpoises).
Karyotypic relationships have been studied using chromosome banding and molecular cytogenetics.
Molecular data has challenged traditional phylogenetic conceptions in Cetartiodactyla.

Purpose of the Study:

To summarize chromosome evolution in Cetartiodactyla.
To highlight the role of molecular cytogenetic studies in understanding karyotypic phylogeny.
To discuss incongruences between morphological and molecular data in cetartiodactyl phylogeny.

Main Methods:

Review of molecular cytogenetic studies on Cetartiodactyla chromosome evolution.
Comparative mapping of rearranged and distantly related species karyotypes.
Analysis of discordances between morphological and molecular phylogenetic data.

Main Results:

Molecular cytogenetics facilitates comparative mapping across diverse Cetartiodactyla species.
Cetacea is revealed as a deeply nested clade within Artiodactyla.
Incongruences exist between morphological and molecular phylogenies for major artiodactyl clades.

Conclusions:

Molecular cytogenetics is crucial for reconstructing ancestral karyotypes and understanding chromosome evolution in Cetartiodactyla.
The deep nesting of Cetacea within Artiodactyla is a significant finding from molecular phylogeny.
Revisiting cetartiodactyl phylogeny with molecular data is essential for accurate evolutionary understanding.
