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...

Gene Evolution - Fast or Slow?

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...

Genetics of Speciation

Genetics of Speciation

Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.

Diversity of Protists III

Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...

Diversity of Archaea III

Crenarchaeota, a prominent phylum of Archaea, is remarkable for its ability to thrive in extreme environments characterized by high temperatures and acidity. These microorganisms inhabit sulfuric hot springs, volcanic systems, and submarine hydrothermal vents, where temperatures often exceed 100°C. The unique adaptations of Crenarchaeota not only allow survival under such extreme conditions but also provide insights into the mechanisms of life in primordial Earth-like...

Area of Science:

Microbial Ecology
Evolutionary Biology
Genomics

Background:

Gut microbial communities significantly influence host evolution.
The relationship between gut microbiota composition and host divergence time is not well understood.
Glires (lagomorphs and rodents) represent a suitable model for studying host-microbe co-evolution.

Purpose of the Study:

To investigate the gut microbiota composition in eight Glires species.
To explore the correlation between gut microbial divergence and host evolutionary divergence time.
To understand the role of gut microbiota in host phylogeny.

Main Methods:

Comparative analysis of gut microbiota in four lagomorph and four rodent species.
Phylogenetic reconstruction of host-microbe divergence.
Calculation of host phylogeny and divergence times.
Analysis of microbial alpha diversity and community structure using Shannon diversity, evenness, weighted UniFrac, and Bray-Curtis dissimilarity.

Main Results:

Lagomorphs and rodents exhibit distinct gut microbial compositions, with lagomorphs dominated by Firmicutes and rodents by Bacteroidetes.
Significant differences in alpha diversity were observed among lagomorph species, but not among rodent species.
Gut microbial dissimilarity in Glires is positively correlated with host divergence time.
Core bacterial genera involved in plant polysaccharide degradation showed significant changes within lagomorphs.

Conclusions:

Gut microbial composition is associated with host phylogeny in Glires.
Gut microbiota dissimilarity can potentially predict host divergence time.
These findings provide insights into the co-evolutionary dynamics between hosts and their gut microbiota.
