The bluebuck and sable antelope diverged from each other 2.8 million years ago, while the roan antelope diverged from both of them 4.17 million years ago. Africa was going through climatic oscillations between 3.5 and 2 million years ago, and during a colder period, the ancestors of the sable antelope and bluebuck may have been separated, and ...
Like other hartebeests, the bubal was a social animal. Luis del Mármol Carvajal wrote in 1573 that herds of 100 to 200 animals could be found in northern Morocco. According to 19th century writers, the bubal hartebeest preferred rocky areas with a fair amount of vegetation, in contrast to the sandy, drier habitat of the Addax.
In a study on the effect of place and sex on carcass characteristics, the average carcass weight of the male red hartebeest was 79.3 kg (174 + 3 ⁄ 4 lb) and that of females was 56 kg (123 lb). The meat of the animals from Qua-Qua region had the highest lipid content—1.3 g (20 gr) per 100 g ( 3 + 1 ⁄ 2 oz) of meat.
Photographer Tim Flach is renowned for his photos that show the more human side of suffering animals.
Some antelopes have been domesticated including the oryxes, addax, elands and the extinct bubal hartebeest. In Ancient Egypt oryxes, addaxes and bubal hartebeests are depicted in carved walls. [citation needed] The earliest evidence of cattle domestication is from 8000 BC, suggesting that the process began in Cyprus and the Euphrates basin. [70]
Extinction of taxa is difficult to confirm, as a long gap without a sighting is not definitive, but before 1995 a threshold of 50 years without a sighting was used to declare extinction. [ 1 ] One study found that extinction from habitat loss is the hardest to detect, as this might only fragment populations to the point of concealment from humans.

Red list categories of the IUCN Demonstrator against biodiversity loss, at Extinction Rebellion (2018).. The current rate of global biodiversity loss is estimated to be 100 to 1000 times higher than the (naturally occurring) background extinction rate, faster than at any other time in human history, [25] [26] and is expected to grow in the upcoming years.
