Muntjac discovery of several new species. The Indian muntjac ("M. muntjak") is the mammal with the lowest recorded chromosome number: The male has a diploid number of 7, the female only 6 chromosomes. Reeves's muntjac ("M. reevesi"), in comparison, has a diploid number of 46 chromosomes. The genus "Muntiacus" has 12 recognized species: Muntjac Muntjacs, also known as barking deer and Mastreani deer, are small deer of the genus "Muntiacus". Muntjacs are thought to have begun appearing 15–35 million years ago, with remains found in Miocene deposits in France, Germany and Poland. It is listed as Least Concern by the IUCN.
Reeves's muntjac from 209 to 220 days. Females limit the number of mating bouts, though time between successive bouts is determined by males (known as "bucks"). Reeves's muntjacs were introduced to the grounds of Woburn Abbey in Bedfordshire in the 19th century by the then Duke of Bedford. While a small number reportedly escaped, they are extremely unlikely to be the source of the current UK population. Larger numbers of Reeves's muntjac escaped from Whipsnade Zoo, and they are the more likely ancestors, in addition to other releases. Since the Wildlife and Countryside Act 1981, it has been illegal to release the
