Evolutionary Relationships through Genome Comparisons02:54

Evolutionary Relationships through Genome Comparisons

7.1K
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...

Single Nucleotide Polymorphisms-SNPs

18.7K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

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...

Overview of Transposition and Recombination

19.6K
Transposons make up a significant part of genomes of various organisms. Therefore, it is believed that transposition played a major evolutionary role in speciation by changing genome sizes and modifying gene expression patterns. For example, in bacteria, transposition can lead to conferring antibiotic resistance. Movement of transposable elements within the genetic pool of pathogenic bacteria can aid in transfer of antibiotic-resistant genetic elements. In eukaryotes, transposons can carry out...

The Evidence for Evolution02:55

The Evidence for Evolution

48.6K
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.

Gene Evolution - Fast or Slow?02:05

Gene Evolution - Fast or Slow?

8.3K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

Area of Science:

  • Primate Genetics
  • Population Genetics
  • Evolutionary Biology

Background:

  • Male dispersal is common in baboons (Papio) and impacts population structure and evolution.
  • Direct observation of long-distance dispersal is challenging.
  • Genetic markers offer a novel approach to study baboon dispersal patterns.

Purpose of the Study:

  • To investigate baboon population structure using genome-wide Alu insertion polymorphisms.
  • To assess the influence of male dispersal on population genetics in yellow (Papio cynocephalus) and kinda (Papio kindae) baboons.

Main Methods:

  • Utilized 494 genome-wide Alu insertion polymorphisms from the Baboon Genome Analysis Consortium.
  • Analyzed genetic variation in mixed and unmixed populations of yellow and olive (Papio anubis) baboons.
  • Examined genetic differentiation between social groups of kinda baboons.

Main Results:

  • Alu insertion variation successfully identified hybrid individuals in mixed baboon populations.
  • Genetic similarity was higher between neighboring yellow baboon groups, indicating structuring by male dispersal distance.
  • Kinda baboon populations showed sharp genetic differences between neighboring groups, suggesting infrequent intergroup migration.

Conclusions:

  • Alu insertion polymorphisms are effective tools for reconstructing baboon population structure and inferring dispersal patterns.
  • Male dispersal significantly structures yellow baboon populations.
  • Intergroup migration appears to be rare in kinda baboons, warranting further investigation.
