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,...

Convergent Evolution

28.1K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

What is Evolutionary History?

36.9K
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.

The Evidence for Evolution

43.1K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...

Area of Science:

  • Marine Biology
  • Evolutionary Biology
  • Paleontology

Background:

  • Scleractinian corals are molecularly classified into robust, complex, and basal clades.
  • Limited morphological or biological criteria exist to systematically determine evolutionary trajectories of these clades.

Purpose of the Study:

  • To investigate structural differences in scleractinian coral colonies, specifically polyp-canal systems.
  • To correlate structural characteristics with evolutionary trajectories of robust and complex coral clades.

Main Methods:

  • High-resolution micro-computed tomography (micro-CT) was employed.
  • Reconstruction of polyp-canal systems in 21 scleractinian coral species.
  • Visualization of dynamic polyp growth processes.

Main Results:

  • The emergence of mesh-like canals appears to distinguish complex from robust coral clades.
  • Differences in polyp-canal connections suggest distinct evolutionary trajectories.
  • More complex coral structures, facilitated by canal networks, led to uniform calyx volumes and precise axial growth.

Conclusions:

  • Coral canal network formation promotes complex structures and efficient niche occupation.
  • Individual polyp influence diminishes with increasing colony complexity.
  • Findings supplement evolutionary studies and offer insights into coral growth patterns.
