Synteny and Evolution02:31

Synteny and Evolution

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 chromosome underwent...
Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes02:16

Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes

The present-day mitochondrial and chloroplast genomes have retained some of the characteristics of their ancestral prokaryotes and also have acquired new attributes during their evolution within eukaryotic cells. Like prokaryotic genomes, mitochondrial and chloroplast genomes neither bind with histone-like proteins nor show complex packaging into chromosome-like structures, as observed in eukaryotes. Unlike mitotic cell divisions observed in eukaryotic cells, mitochondria and chloroplasts...
Multi-species Conserved Sequences02:51

Multi-species Conserved Sequences

Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale  studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved DNA...
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...
Genome Size and the Evolution of New Genes03:21

Genome Size and the Evolution of New Genes

While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.

Area of Science:

  • Genomics
  • Evolutionary Biology
  • Primate Genetics

Background:

  • The release of human genome sequences in 2001 spurred interest in primate genetics.
  • Comparative genomic analyses, particularly with the mouse genome, focus on functional, evolutionary, and diversity aspects of human DNA.

Purpose of the Study:

  • To reconstruct the genomic evolutionary processes shaping the human lineage after divergence from mice.
  • To establish a phylogenetic framework for analyzing character evolution across major primate groups.
  • To understand genotype-phenotype correlations and the emergence of human-specific traits through functional genomics.

Main Methods:

  • Analyzing molecular character states in representatives of major primate groups.
  • Utilizing Whole Genome Shotgun (WGS) sequencing for primate genomes.
  • Leveraging comparative data from functional genome parts (e.g., ENCODE project).

Main Results:

  • Availability of genome sequences for rhesus monkeys and chimpanzees.
  • Ongoing generation of several primate genome sequences.
  • Comparative data on functional genomic elements are being compiled.

Conclusions:

  • Comparative primate genomics is essential for understanding human evolution.
  • Reconstructing evolutionary processes requires a robust phylogenetic framework linking species.
  • Functional genomic studies in primates will illuminate genotype-phenotype correlations and human uniqueness.
