First fossil of Homo Naledi child of humankind has been recently discovered

Homo Naledi

A young child’s fossil has been preserved in the darkness of South Africa’s Rising Star cave for hundreds of thousands of years. The skull, which belonged to a youngster aged 4 to 6 years at the time of death, is the earliest known to belong to Homo Naledi, an ancient human cousin. The infant was most likely born between 236,000 and 335,000 years ago, based on the dates of other cave remnants.

According to Juliet Brophy, “this is the first partial skull of a youngster of Homo Naledi that has been unearthed, and it begins to provide us with insight into all stages of life of this amazing species.”

The child’s gender is uncertain, however, researchers have dubbed the fossil Leti and frequently refer to Leti as female. The name derives from the Setswana word Letimela, which means “lost one” in one of South Africa’s 11 official languages.

The findings were reported in PaleoAnthropology in two publications. The first publication details the skull itself, while the second concentrates on the placement of Leti inside the cave system.

Lee Berger, a professor at the University of the Witwatersrand who reported the discovery of the previously unknown Homo Naledi species in 2015, led the research team that uncovered the partial skull, which was pieced from 28 parts and six teeth. Leti’s body has vanished with no trace.

Leti died of unknown causes, and her age is determined from her teeth. However, because we don’t know how quickly Homo Naledi youngsters developed at the moment, she may have been younger, according to the researchers.

Leti was discovered in 2017 in an exceedingly isolated corridor of the Rising Star Cave System, just 39 feet from where Berger’s team uncovered the first Homo Naledi bones in the Dinaledi Chamber. The cave system is located in the Cradle of Humankind, a UNESCO World Heritage Site in South Africa’s Gauteng area.

Her cranial parts were recovered from a limestone shelf in an exceedingly tiny tunnel approximately 5.9 inches broad and 31.4 inches long. The ledge was approximately 31 inches above the cave floor. Probably, her skull was deliberately put there. Researchers are currently looking into whether the cave system is indeed a Homo Naledi burial site.

It was formerly thought that only contemporary people buried their dead. Leti’s finding is comparable to the discovery of Neo, the bones of an adult male Homo Naledi from another chamber, along a tight corridor.

According to Marina Elliott, cave site research author, excavation team leader, and one of the founding members of the all-female Underground Astronauts in the initial expedition to discover Homo Naledi, excavating Leti was extremely tough.

After reconstructing the fragmentary skull, the researchers compared it to ancient people of comparable sizes, such as the early human-related Australopithecus africanus. According to their findings, Leti’s braincase could have supported a brain weighing between 177 and 240 cubic inches, or around 90% to 95% of the size her brain would have been if she had reached maturity.

Homo Naledi was a curious mash-up of the ancient and the fully contemporary. According to experts, Naledi’s brain is the size of an orange, and its hands appear to be human-like. However, the finger bones are curved, indicating climbing and tool-use ability.
