Evolutionary Relationships through Genome Comparisons02:54

Evolutionary Relationships through Genome Comparisons

6.2K
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?

7.4K
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

Genetic Screens02:46

Genetic Screens

5.1K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Area of Science:

  • Taxonomy and Systematics
  • Entomology
  • Lepidoptera research

Background:

  • Taxonomic revisions are crucial for accurate classification and understanding of biodiversity.
  • Previous taxonomic work may contain preoccupied names or require updates based on new findings.
  • The Riodinidae and Hesperiidae families are significant groups within Lepidoptera, necessitating ongoing systematic study.

Purpose of the Study:

  • To propose a new substitute name, Lochris, for the preoccupied genus Locris (Lepidoptera: Riodinidae).
  • To describe five new species and five new subspecies of butterflies within the Riodinidae and Hesperiidae families.
  • To provide updated distribution data and confirm species status through sequencing.

Main Methods:

  • Nomenclatural revision, including the proposal of a new substitute name (nom. nov.).
  • Description of new species (sp. n.) and subspecies (ssp. n.) with type localities.
  • Illustration of sequenced specimens and DNA sequencing for taxonomic confirmation.

Main Results:

  • A new name, Lochris Grishin, is proposed for Locris Grishin, 2025 (preoccupied).
  • Five new species are described: Emesis (Mandania) mandarina, Emesis (Mandania) mandela, Telegonus (Rhabdoides) flavifimbro, Urbanus (Urbanoides) dolus, and Thespieus grandosul.
  • Five new subspecies are described: Telegonus (Rhabdoides) alector obscuratus, Burnsius communis tenebrunis, Burnsius communis altus, Ochlodes (Ochluma) sylvanoides paranapa, and Ochlodes (Ochluma) sylvanoides dempwolfi.

Conclusions:

  • The proposed nomenclature ensures taxonomic stability for the affected Riodinidae genus.
  • The description of new taxa expands the known diversity within Riodinidae and Hesperiidae.
  • Updated data and sequencing support the validity and distribution of these butterfly species.
