The Neanderthals, and Denisovans,Homeor Naledi, and New information about 13,500 Homosassa Sapiens who were discovered in Yucatan, in Mexico, suggesting that 23,000 years ago, people came across the bridge at the bering straits to populate the Americas.
Homo Naledi is a new species discovered to be part of the human ancestral lineage. The discovery was, made in South Africa at a place called the Star Cave. This writing will discuss the interesting traits of the Homo Naledi and proceed to state why this discovery is as interesting to the anthropologist community.
Homo Naledi comes forth as the largest fossil find ever made in the African continent with 1550 fossil elements. What is so interesting to the anthropologist community is, Homo Naledi is a new species belonging to an extinct hominin. Homo Naledi main traits are its small body mass comparable to small-bodied humans. Additionally the homo Naledi endocranial volume is as small as that of the australopiths (Stephanie 15). Like its relations, Homo Naledi is very similar to Homohabilis and Homo erectus. Like the modern human Homo, Naledi has a similar wrist and hand. It is also, seen in the 15 more individuals whose skeletal elements were represented multiple samples.
Stephanie (15) notes that one of the most interesting factors to Anthropologists is the connection of the genus Homo which suggested f the discovery stood in as an addition to our hominin ancestry. However, amidst the excitement Homo Naledi seemed to transverse both ends of the hominin space and time. The hands, the wrists, and the feet looked similar to a modern human. The head a smaller braincase, the shoulders the ribcage, and the pelvis all, on the other hand, had which was far too similar to the earlier species that existed around two to four million years ago. The challenge and the excitement arise from the mixed traits that seem to envelop the whole discovery.
Even far interesting to the Anthropologists is the way the fifteen individuals were found deep in a cave. Scientific evidence showed the only way the individuals might have entered the cave was, only if they were taken there. It is suggested that the burial was nothing but intentional. With this behavioral trait, it is only clear that homo Naledi is far different with traits from the ancestral lineage and others from the modern genus resulting in a mix of traits from different hominins.
The reason these traits have gathered such interests is because, there is yet to be an agreement that the homo Naledi deserves it own species slot. Some paleoanthropologists still believe that there is a possibility that the Homo Naledi does not yet warrant the Homo placement it has received. John (5) notes that there some Anthropologist still question whether the Homo Naledi is just another variant form of already well-known species like Homo erectus.
Surprising enough is how small the Homo Naledi brain was, compared with other hominins including the modern man. It is in addition to the fact that the cranium is as rounded as that of other Hominin species. However even more amazing is the fact that the time question is not yet solved. The main reason to this is because the fossils were not encased neither were they close to any foreign datable material. Making this even more difficult no singular organisms were, found close to the fossils that could be, used for dating.
Inability to date the fossils from surrounding objects leaves only two options both of which raise the issue of accuracy. The radiocarbon dating method that could be done on the fossils is only accurate in fossils that are 50,000 years or younger. Consequently, this dating method also raises the issue of age limit as it poses the risk of providing an upper age limit.
Another possible method that could be, used is the electron spin that according to Stephanie (35) is very difficult to apply accurately.
Stephanie (35) states that Homo Naledi reaffirms the thought that evolution is, linear in nature is wrong. Human evolution is the pattern like a bush, which breaks into many lineages. The majority of this lineages are have ceased to exist. However, it might occur to some that age is not as important as most of the analysis relies on relationships created strictly through grouping organisms evolutionarily. According to this statement then it could be concluded that Homo Naledi is an earlier species, which survived for a long time thereby resulting in its closeness to the present genus. All the same, it is, argued that fossil age helps in creating a period that increases the accuracy of the conclusion.
In conclusion, what seems to push the discussion further and further creating even more excitement is the unknown. There remains a lot to be, discovered about Homo Naledi, one among this being age. There remain questions about its membership to our Homo genus. While at the same time, there is the possibility of it being just a variation. In addition to this questions about where it lived? Why it has so many mixed traits or how its remains were so many in the one-place push for more desire to explore.
