The breast of Bigogwe

The Holocene calendar, also known as the Holocene Era or Human Era (HE), is a year numbering system that adds exactly 10,000 years to the currently dominant (AD/BC or CE/BCE) numbering scheme, placing its first year near the beginning of the Holocene geological epoch and the Neolithic Revolution, when humans transitioned from a hunter-gatherer lifestyle to agriculture and fixed settlements. The current year by the Gregorian calendar, AD 2021, is 12021 HE in the Holocene calendar. The HE scheme was first proposed by Cesare Emiliani in 1993 (11993 HE).

The breast of Bigogwe, commonly known as “Ibere rya Bigogwe” in Kinyarwanda is a 2597 metres long rock, which is located in Rubavu district, Rwanda.

The wild Bactrian camel (Camelus ferus) is a critically endangered species of camel living in parts of northwestern China and southwestern Mongolia. It is closely related to the Bactrian camel (Camelus bactrianus). Both are large, double-humped even-toed ungulates native to the steppes of central Asia. Until recently, wild Bactrian camels were thought to have descended from domesticated Bactrian camels that became feral after being released into the wild. However, genetic studies have established it as a separate species which diverged from the Bactrian camel about 1.1 million years ago. Only about 1,000 camels are extant. Most live on the Lop Nur Wild Camel National Nature Reserve in China, and a smaller population lives in the Great Gobi A Strictly Protected Area in Mongolia. There are also populations in the Altun Shan Wild Camel Nature Reserve (1986) in Qakilik County, in the (1992), and in (now Dunhuang Xihu Wild Camel Nature Reserve) contiguous with the reserve in Qakilik (2001) and a reserve in Mazongshan contiguous with the reserve in Mongolia, all in China.
