Today there remain but two lineages: the domestic horse and
Przewalski's horse, also called the Mongolian wild horse.
The theme of this week's programme is animals in danger, and they range from Mongolia's wild
Przewalski's horse to the near-extinct Manta ray in the Maldives.
Among other things, he described
Przewalski's horse and Przewalski's gazelle, which were both named after him.
The results of the analysis show that
Przewalski's horse, rescued from extinction in the 20th century classified as an endangered species, is a descendant of horses, domesticated about 5500 years ago by representatives of the Botai culture in Kazakhstan.
Two of Central Asia's rarest species,
Przewalski's Horse and the Gobi Bear, should be protected with stricter conservation measures, experts said ahead of an international conference in Manila.
Horse domestication and conservation genetics of
Przewalski's horse inferred from sex chromosomal and autosomal sequences.
Similar results were also found for
Przewalski's horse living in a similar environment (Zheng et al., 2001; Souris et al.
2006: Capture and anesthesia of wild Mongolian equids--the
Przewalski's horse (E.ferus przewalskii) and khulan (E.
By lining up the DNA from the ancient and modern horses, the researchers concluded that
Przewalski's horse is a separate, truly wild species that split sometime between 38,000 and 72,000 years ago from the lineage that led to domestic horses.
Among other insights, the sequence supports the often-debated view that the
Przewalski's horse, native to the Mongolian steppes, is the last living population of truly wild horses in the world.
The analysis also found new evidence that an endangered animal called the
Przewalski's horse, found in Mongolia and China, is the last surviving wild horse.
