Summary
Forensic science educators adapted a hands-on forensic entomology lab for remote learning. This virtual exercise teaches students to identify unknown specimens using phylogenetic trees and public databases.
Area of Science:
- Forensic Science
- Molecular Systematics
- Entomology
Background:
- The COVID-19 pandemic necessitated virtual adaptation of applied forensic science courses.
- Traditional laboratory components in forensic science education faced challenges in remote learning environments.
Purpose of the Study:
- To develop a remote laboratory exercise for forensic entomology education.
- To provide students with practical skills in specimen identification using molecular data.
Main Methods:
- Students utilized public databases to retrieve sequence data.
- Phylogenetic trees were generated from sequence data.
- Students identified an unknown specimen by comparing it to their generated phylogenies.
Main Results:
- The remote exercise successfully simulated a traditional forensic entomology lab.
- Students learned to apply molecular systematics to identify forensic specimens.
- The exercise was adaptable for various academic levels.
Conclusions:
- This virtual lab exercise effectively bridges molecular systematics and forensic education.
- It offers a viable alternative for practical laboratory components in forensic entomology.
- The publicly available resource aids in understanding forensic question resolution.

Evolutionary Relationships through Genome Comparisons
6.1K
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...

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...

Bacterial identification relies on a diverse array of techniques to classify and understand microorganisms, each tailored to uncover specific characteristics. Traditional morphological approaches, while still valuable, are limited for closely related or structurally simple organisms. Modern methods integrate biochemical, serological, genetic, and advanced molecular tools to achieve greater accuracy.Morphological and Biochemical TechniquesMorphological characteristics, such as cell shape and...

Phylogeny
45.2K
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 Trees
45.8K
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.
