The Evidence for Evolution02:55

The Evidence for Evolution

48.4K
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.

Convergent Evolution01:54

Convergent Evolution

33.1K
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.

Self-Concept01:19

Self-Concept

1.7K
Self-concept is the cognitive and emotional understanding individuals hold about their identity. It evolves through various developmental stages, beginning in infancy and maturing as children grow. This concept influences how individuals perceive their abilities, interact with others, and manage challenges throughout life.
Infancy and Emerging Recognition
During infancy, self-concept is virtually nonexistent. Babies do not distinguish themselves as separate entities and often mistake their...

Protein Networks02:26

Protein Networks

4.6K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Eukaryotic Evolution01:24

Eukaryotic Evolution

42.3K
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...

Synteny and Evolution02:31

Synteny and Evolution

3.8K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
Around 80 million years ago, the human and mice lineages diverged from the common ancestor. During the course of evolution, the ancestral...

Area of Science:

  • Neuroscience
  • Movement Disorders
  • Genetics

Background:

  • Dystonia is characterized by heterogeneity in causes, classification, and clinical presentation.
  • It is increasingly viewed as a network disorder affecting cortico-thalamic-basal ganglia pathways.
  • Emerging evidence suggests a role for cerebellar pathways in dystonia pathogenesis.

Purpose of the Study:

  • To review recent advances in human degenerative ataxias and dystonia rodent models.
  • To discuss the pathogenesis of dystonia, integrating human and animal study findings.
  • To explore the concept of dystonia as a network disorder.

Main Methods:

  • Literature review of recent human degenerative ataxias.
  • Analysis of discoveries from dystonia rodent models.
  • Synthesis of findings from human and animal studies.

Main Results:

  • Dystonia exhibits significant heterogeneity, affecting multiple brain regions and cellular mechanisms.
  • Pathophysiological alterations involve cortico-thalamic-basal ganglia dysfunction.
  • Cerebellar pathways are increasingly recognized for their role in dystonia.

Conclusions:

  • Dystonia is a complex network disorder with heterogeneous origins.
  • Multiple brain regions and cellular mechanisms contribute to neural dysfunction in dystonia.
  • Integrating human and animal research advances our understanding of dystonia pathogenesis.
