Fossil discoveries in Ethiopia confirm that the first type of this type Homo Live with other hominids, such as AustralopithecusAbout 2.6 million years ago. This new evidence fills a gap in the fossil registry of human development, which shows that development was not written, but it is a more complicated process with various types of living side by side and competing for resources, which has led to the development of human characteristics.

Researchers in the LEDI-ERARUU Research Project (LEDI-EGRAU, Ethiopia, is very rare of species Homo and Australopithecus Dated between 2.78 and 2.59 million years – a critical period, but it has not been represented in the African Al -Ahfar record. The study was published in the prestigious magazine nature This Wednesday (13/8).

The result is especially important because this interval coincides with the decisive events: the appearance of the first human beings (HOMO), the appearance of paranoia And the disappearance of the famous Australopithecus AfarensisThe types belonging to the famous fossils “Lucy”.
New fossils include good reserved teeth and tooth fragments. Among them is LD 302-23 Premolar, dated 2.78 million years, lineage to this type of HOMO, and molars of about 2.59 million years that also belong to primitive human individuals. At the same time, fossils Australopithecus From 2.63 million years, indicating that the two lineage not only coexisted, but also participated in the same region for thousands of years.

This coexistence has occurred in a more dry and open environment, challenging the traditional idea that these habitats will be exclusively linked to the emergence of HOMO type. “These results show us that the evolutionary scenario was more complicated than we thought. There was not only one proportions; several types were divided into the same area and perhaps similar resources,” the researchers explained.
Geological analysis and accurate dating confirms that a distant area deposit maintains records for this main period. This places Lidarro as a basic piece of rebuilding the timetable for human development.
The study also raises the possibility that some fossils represent a kind of Australopithecus So far, science is unknown. If confirmed, this hypothesis will already expand the diversity of diversity 2.5 million years ago – a time when East Africa was real mosaic for human ancestors.
