Complete mitochondrial genome of an extinct Equus (Sussemionus) ovodovi specimen from Denisova cave (Altai, Russia).
Abstract: is an extinct subgenus of first characterized and delineated in 2010. The almost complete mitochondrial genome is available only for a single specimen of - a 40,000 years old from Proskuryakova cave (Khakassia, Russia). Our studies of ancient horses from Denisova cave (Altai, Russia) revealed mitochondrial DNA of this species in a 32,000 years old sample. Using alignments to multiple mitochondrial genomes of non-caballine equids, we recovered 100% complete mitochondrial genome of for the first time. Phylogenetic analysis demonstrates close relationship between this individual and the one previously described in Khakassia.

This research deals with the extinct subgenus of Equus, Sussemionus ovodovi. The scientists have successfully acquired the complete mitochondrial genome from a 32,000-year-old sample from an extinct equus specimen found in Denisova cave in Russia. The findings have also demonstrated a close relationship between this individual and a previously described one found in Khakassia, Russia.
Objective of the Research
- The main objective of the research was to extract and investigate the complete mitochondrial genome of an extinct Equus known as Sussemionus ovodovi, from a fossil specimen.
Study and Methods
- The researchers conducted the study on ancient horses discovered from the Denisova cave in Altai, Russia.
- They processed a 32,000 year-old sample to retrieve the mitochondrial DNA of this extinct species.
- The researchers then utilized alignments to various mitochondrial genomes of non-caballine equids to achieve a complete mitochondrial genome recovery.
Results and Findings
- The study successfully resulted in the recovery of a 100% complete mitochondrial genome of Sussemionus ovodovi for the very first time.
- The researchers conducted phylogenetic analysis which showcased a close relationship between the analyzed individual and a previously described one located in Khakassia, Russia.
Significance of the Study
- The study sets a precedent by attaining an entire mitochondrial genome from an extinct subspecies which will set the path for further investigations in the field.
- The results can contribute significantly to evolutionary biology by deepening the understanding of extinct species and their genetic makeup.
