Epistasis01:39

Epistasis

50.6K
In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...

Convergent Evolution01:54

Convergent Evolution

33.5K
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.

Gene Duplication and Divergence02:37

Gene Duplication and Divergence

8.1K
The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was  generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are...

Dosage Compensation02:50

Dosage Compensation

7.7K
In animals, gender is determined by the number and type of sex chromosome. For example, human females have two X chromosomes, and males have one X and one Y chromosome, whereas C.elegans with one X chromosome is a male, and the one with two X chromosomes is a hermaphrodite.
In addition to sexual development, the X chromosome has genes involved in autosomal functions such as brain development and the immune system. Therefore, males and females with  distinct numbers of X chromosomes will...

Cell Signaling in Plants01:25

Cell Signaling in Plants

6.8K
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

Synteny and Evolution02:31

Synteny and Evolution

3.9K
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:

  • Comparative psychology
  • Neuroscience
  • Evolutionary biology

Background:

  • Stereopsis, the perception of depth from binocular vision, was historically believed to be exclusive to primates.
  • Recent discoveries reveal stereopsis in a wide array of animals, including prey mammals, birds, amphibians, and invertebrates.

Purpose of the Study:

  • To investigate the evolutionary principles, functional roles, and underlying mechanisms of stereopsis across the animal kingdom.
  • To explore whether diverse animal species utilize similar or varied algorithms for stereopsis.
  • To identify potential applications of animal stereopsis mechanisms in machine vision.

Main Methods:

  • Review of current scientific literature on animal stereopsis.
  • Comparative analysis of stereopsis across different animal taxa.
  • Exploration of evolutionary pressures and functional advantages driving stereopsis.

Main Results:

  • Stereopsis is more widespread across the animal kingdom than previously thought.
  • The diversity of stereopsis suggests varied evolutionary paths and potential for diverse underlying mechanisms.
  • Understanding animal stereopsis can inform the development of novel machine vision systems.

Conclusions:

  • The widespread presence of stereopsis necessitates further research into its evolution and diverse mechanisms.
  • Investigating animal stereopsis can provide insights into optimal algorithms for machine vision.
  • Future research should explore novel stereopsis mechanisms and their role in camouflage evolution.
