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...
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...
Eukaryotic Evolution01:24

Eukaryotic Evolution

The endosymbiont theory is the most widely accepted theory of eukaryotic evolution; however, its progression is still somewhat debated. According to the nucleus-first hypothesis, the ancestral prokaryote first evolved a membrane to enclose DNA and form the nucleus. Conversely, the mitochondria-first hypothesis suggests that the nucleus was formed after endosymbiosis of mitochondria.
Contrary to the endosymbiont theory, the eukaryote-first hypothesis proposes that the simpler prokaryotic and...
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...

What is Evolutionary History?02:35

What is Evolutionary History?

Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.Phylogenetic trees illustrate the evolutionary relationships among these organisms. Scientists infer organisms’ common ancestry by evaluating shared morphological and genetic characteristics. Together, the fossil...

Area of Science:

  • Evolutionary Biology
  • Developmental Biology
  • Insect Phylogenetics

Background:

  • Phylogenetic reconstruction benefits from integrating molecular and morphological data.
  • The interplay between developmental and evolutionary biology offers new research avenues, termed the phylo-evo-devo approach.

Purpose of the Study:

  • To revisit the evolutionary placement of Strepsiptera and Diptera using molecular data.
  • To investigate the evolutionary basis of wing and haltere development in holometabolous insects.

Main Methods:

  • Molecular phylogeny of holometabolous insect orders.
  • Analysis of Hox gene Ultrabithorax in relation to morphological traits.

Main Results:

  • The molecular phylogeny indicates Strepsiptera are closely related to Coleoptera.
  • This finding challenges recent claims placing Strepsiptera within or near Diptera.
  • The study provides insights into the evolution of insect wing and haltere development.

Conclusions:

  • Integrating phylogenetics with developmental biology (phylo-evo-devo) provides valuable reciprocal illumination.
  • The evolutionary history of Strepsiptera is clarified, with implications for understanding insect evolution and development.
