这个地区的热水池和温泉里充满了微生物。这种有机体被称为“极端微生物”,因为它们不会在极端环境中繁殖,例如不适宜的丹纳克尔萧条。这些极端微生物可以承受高温,空气中的有毒火山气体,地下高金属浓度以及高含盐量和酸含量。 Danakil大萧条中的大多数极端微生物都是非常原始的原核微生物,它们是我们这个星球上最古老的一些生命形式。由于丹纳克尔周围的环境不友善,这个地区似乎在人类进化中发挥了作用。 1974年,由古人类学家唐纳德约翰逊领导的研究人员发现了一个绰号为“露西”的南方古猿妇女的化石遗骸。她的物种学名是“australopithecus afarensis”,作为对她和其他同类化石已被发现的地区的贡献。这一发现导致这个地区被称为“人类的摇篮”

加拿大维多利亚大学Assignment代写:Danakil 戈壁里的生命

The hydrothermal pools and hot springs in this region are teeming with microbes. Such organisms are called “extremophiles” because they not thrive in extreme environments, like the inhospitable Danakil Depression. These extremophiles can withstand high temperature, toxic volcanic gases in the air, high metal concentrations in the ground, as well as high saline and acid content. Most extremophiles in the Danakil Depression are extremely primitive, prokaryotic microbes, some of the most ancient lifeforms on our planet. As inhospitable as the environment is around Danakil, it seems that this area played a role in the evolution of humanity. In 1974, researchers led by paleoanthropologist Donald Johnson found the fossil remains of an ​Australopithecus woman nicknamed “Lucy”. The scientific name for her species is “australopithecus afarensis” as a tribute to the region where she and fossils of others of her kind have been found. That discovery has led to this region being dubbed the “cradle of humanity”.
