Even the most fundamentalist and industry mailing list open to debate experts admit other species in this period and in other regions, as we shall see in the next chapter. The second departure from Africa Between 800,000 and 600,000 years ago, our planet experienced a new climate transition, with much harsher consequences than the previous one 2.6 million years ago. At this time begins a series of glacial pulses of different characteristics to the previous ones and in which we are still immersed. This glacial pulse will be characterized by temperatures even lower than those achieved in previous cold industry mailing list and by the spread of large masses of ice (or ice) over northern Europe and North America.

The previous climate cycle of 41,000 industry mailing list is replaced by another of 100,000 years, this time controlled by the shape of the orbit (more or less eccentric) and not by the obliquity of the Earth's axis. Unlike the 41,000-year cycles, As a result, a cold steppe will spread across much of Europe and Asia. Large industry mailing list adapted to these new conditions will dominate terrestrial ecosystems, such as steppe mammals ( Mammuthus trogontherii ), steppe rhinos ( Stephanorhinus hemitoechus ), modern-looking horses ( Equus mosbachensis ), bison ( Bison priscus ). ) or the first wild oxen ( Bos primigenius). Unlike the high latitudes, in Africa these glacial pulses will not result in significant drops in temperature but in phases of marked aridity, with new expansions of the dry industry mailing list and, most likely, also of the desert.

Along the way were the last paranthropes, which industry mailing list a million years ago. Although the record of African hominids in the period between one million and 600,000 years ago is very poor, there are indications that Homo ergaster continued to evolve, according to several relatively well-preserved cranial remains from the Layer. 2 from Olduvai, Buia, Eritrea, and Bouri, the Middle Awash in Ethiopia . All these remains retain characters that make them reminiscent of Homo erectus, but at the same time they already show more advanced characters towards a new type of hominid, such as the possession of a cranial box that rises vertically. Homo rhodesiensis Cf. Topic 20. Homo antecessor, rhodesiensis, heidelbergensis and floresiensis of the online course Origins of art and human evolution: homo significans . Online at And indeed, from about 600,000 years ago we find the first evidence of a new human form, characterized by a high cranial capacity, which can reach up to 1,400 cc. This species was already recognized in Africa in the early 20th century, when a well-preserved skull was excavated alongside other skeletal remains in the town of Broken Hill
