THE ‘Sima del Elefante’ (‘Chasm of the Elephant’) is a sequence of underground caves in a limestone outcrop close to Atapuerca, a village just a few miles outdoors Burgos.
The cave system has lengthy been recognized to own prehistoric human fragments and is at present being excavated by a staff from the College of Burgos. The dig has definitely paid dividends: the face a part of a really historic man has been uncovered, including to our understanding of human origins.
A chunk from an grownup man’s left cheek and higher jaw has come to gentle, relationship again 1.4 million years, belonging to a member of a human species that has since gone extinct. In the present day, the area is considerably dry and desolate, however again then it was wooded, fertile, and criss-crossed by streams. Wildlife (in different phrases, meals) would have been plentiful within the early Pleistocene age, when what’s now Spain was inhabited by a minimum of two kinds of human.
‘This analysis introduces a brand new actor within the story of human evolution in Europe,’ stated Dr Rosa Huguet of the College of Rovira i Virgili in southern Catalonia, who helped uncover the fossils on the Sima del Elefante cave. We all know that early people reached Eurasia from Africa a minimum of 1.8 million years in the past, as evidenced by 5 skulls relationship from the interval in Dmanisi, Georgia. The skulls are attributed to Homo Erectus, the primary early human species to have left the African continent.

Earlier than this current discover, the earliest human remnants in western Europe had been 1.2 million-year-old items of jawbone and enamel, additionally from Sima del Elefante. Youthful human stays, relationship to 800,000 years in the past, had been unearthed on the close by Gran Dolina (‘Big Sinkhole’) cavern. Explicit options of the latter led researchers to think about them a definite species, specifically Homo Antecessor, or pioneer man.
Writing within the scientific journal Nature, the Spanish archaeologists say the newest stays are extra primitive than Homo Antecessor however resemble Homo Erectus. As a result of the precise provenance of the fragments is tough to fit into our present ‘map’ of human ancestry, the staff has designated the species Homo Affinis Erectus, suggesting that it might be a definite genetic department, however associated to Homo Erectus.
Employees onsite don’t hassle with the tutorial Latin names. They’ve christened the bone fragment ‘Pink’, after Pink Floyd. The rock group’s 1973 album *The Darkish Facet of the Moon*, in Spanish translation, affords the nickname ‘hidden face’, which appeared applicable to the staff.
Dr María Martinón-Torres, the director of the Nationwide Centre for Analysis on Human Evolution in Burgos, has stated that amongst its distinctive traits, ‘Pink’ had a flatter nasal construction than Homo Antecessor, which shares the extra modern-looking face and distinguished nasal bones of Homo Sapiens.
Chris Stringer, a analysis chief on human evolution on the Pure Historical past Museum in London, says the fossil is ‘a vital discover’. In 2023, Stringer and others recognized a interval of utmost cooling about 1.1 million years in the past which will have pushed early people out of western Europe, presumably explaining the totally different inhabitants discovered at Sima del Elefante.
Excavations on the Atapuerca website paint an image of lush meadows and woodlands greater than 1.1 million years in the past, with oaks, pines, juniper, and hazel bushes in abundance. Rivers reducing via the panorama drew water voles and mice, hippos, bison, and deer. Quartz and flint instruments have additionally been recovered alongside animal bones bearing lower marks from butchering.
Extra perception into the Sima del Elefante life-style is clear from a groove that runs throughout the partial crown of a tooth within the ‘Pink’ fossil, believed to be a wear-and-tear mark from utilizing a rudimentary toothpick.
‘That is one other step in direction of understanding the primary Europeans,’ stated Dr José María Bermúdez de Castro, the co-director of the Atapuerca Mission. ‘We now know that this primary species had an look harking back to the specimens included by many in Homo Erectus. Nevertheless, the stays from the Sima del Elefante website have a really explicit mixture of options. Extra fossils needs to be present in different modern websites to succeed in a extra strong conclusion in regards to the identification of this species.’
