Summary
This summary is machine-generated.Ancient DNA analysis of an Asiatic ibex (Capra sibirica) mitochondrial genome confirms the presence of the northern lineage at Tangchaodun Ruins over 650 years ago, showing genetic links to modern populations.
Area Of Science
- Paleogenomics
- Ancient DNA Analysis
- Mitochondrial Genomics
Background
- The Tangchaodun Ruins provide a unique archaeological context for studying ancient fauna.
- Understanding the historical distribution and genetic diversity of Capra sibirica is crucial for conservation efforts.
Purpose Of The Study
- To sequence and analyze the ancient mitochondrial genome of an Asiatic ibex from the Tangchaodun Ruins.
- To determine the phylogenetic position and historical presence of this lineage.
Main Methods
- High-throughput sequencing was employed to obtain the ancient mitochondrial genome.
- Bioinformatic analysis and phylogenetic reconstruction using the maximum-likelihood method (HKY+I+G4 model) were performed.
- Sequence authenticity was validated by analyzing DNA damage patterns.
Main Results
- A complete mitochondrial genome of 16,583 bp was successfully sequenced from an Asiatic ibex specimen.
- The analysis revealed the presence of the northern Capra sibirica lineage at the site, dating back at least 650 years.
- Phylogenetic analysis indicated close genetic affinity between the ancient ibex and modern Capra sibirica populations.
Conclusions
- The study provides molecular evidence for the long-term persistence of the northern Capra sibirica lineage in the region.
- This research contributes to the understanding of ancient caprine population dynamics and genetic history.

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...
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...
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...
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...
Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.
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...
