Human Evolution: What Is It All About And Why Is Homo Sapiens The Only Species Alive, Who Were The Neanderthals? Let's Find Out!

Hello steemit friends, one of the greatest and confused understanding is about human creation, it's anxiousness still remains on how humans came into existence and where did we start, thus this debate is one in which we have to sit down and take moments to imagine on "How did we even came into existence", we end up with no real solid explanation on this question. Lots of scientists brought into theory on how humans were made with lots of creation myths. Humanlike creature which was classified as Homo sapien, being a part of the hominids groups. The hominids was claimed to swing from other primate and this claim was supported by the anthropological and archaeological theory, thus this evidence wrote that the diversion was done around 2 to 4 million years ago, from Africa (southern and eastern coast of Africa).

Different hypothesis were made by various scientists on the evolution of the early hominids, from the savannah hypothesis which claim that due to some environmental changes, which made the forest uncomfortable for those hominids who lived on trees, this changes made the forest region to reduce in size but causing the savannahs to expand, this made the tree-dwelling hominids to adapt to a new living that was as a result of these changes, so the hominids then decided to live on ground and also walked upright rather than living on trees, this hypothesis may seems funny to you but lots of persons including scientists placed their believe on this hypothesis.

Another hypothesis made was that of the aridity hypothesis which also claimed that as a result of the expansion of Africa's dry savannah region resulted to hominids evolving there because they found Africa climate more suitable for them (LOL). Years passes and hominids kept on developing more unique and special qualities which attributed to the increase of their brain capacity, different hominids like the Homo habilis which started developing the idea of using tools despite it's simplicity or not. Other hominids species called Homo erectus, migrated out of Africa to start up living in Eurasia and there they started improving in new advancement. Scientists focused more on Homo sapiens, which they have been trying to theorize on why other hominids were not able to survive, theorising the fact that in hominids species, some are not successively able to survive over one another in terms of getting feeds, the rate at which climate changes and volcanic eruption.

You may want to take a pretty look around, you will see different smart animals but you can't find any species quite like us. This assumption back them wasn't totally true because our own species appeared about two thousand years ago, human species [Homo sapiens] lived with three other species called the Homo floresiensis, Denisovans and Neanderthals. Two million years ago in Africa, several type of creatures that really looked more like the humans, walked the landscape and some looked surprisingly similar to each other while others had different features, we don't know much about the Denisovans to even ask why they died off but all we have from them are two teeth and small finger bone, although the Homo floresiensis didn't live much behind but we can say more about the Neanderthals, they evolved long before us and they were successfully living in Europe for over 200,000 years before we came, the Neanderthals totally got different story.

The first human in 1856 to hold the Neanderthals skull didn't have any idea of what to make of them until Charles Darwin in 1859 in his book "On The Orgin Of Species", which talked about the theory of human evolution like every living being which must have descended from an early species and lot of scientists thought Neanderthals fitted the bills. Ernst Haeckel even tried to name them as Homo stupidus, various scientists had different ideas, they even rebuild skeleton to look like cartoons (cave men), instead they insisted that the Neanderthals was sort of failed evolution. You may want to ask "where do the Neanderthals fit in the human tree", "were they sort of cave men or were they more smart and intelligent that the humans" but if this claim is actually true, why did the Neanderthals suddenly disappeared or did the Neanderthals really disappeared?.

Could the Neanderthals talk?

We know that both humans and the Neanderthals shared same version of genome, the FOXP2 which aid speech and the shape if the Neanderthals and Homo sapiens(we humans) skull had the same structure for speech, like the wernick area and the biocas area which was found to be common between the Neanderthals and we humans, their throat was shaped to make nice sound and this was very necessary for speech. Scientists thinks that the Neanderthals could have exchanged ideas with humans by means of simple sounds, Rhythmic movement and musical tones.

Around fifty thousand years back, Neanderthals met their very smart cousins "us". For five to ten thousand years, winter and summer arranged to overlap until the Neanderthals disappeared about 40 thousands years ago, "were we friends or enemies with the Neanderthals" or probably the Neanderthals population wasn't enough to keep on with life or maybe the Neanderthals was already in danger before Homo sapiens showed up. Before they disappeared, scientists found one gift that the Neanderthals left for us, in May 7 2010 it was known in the Neanderthals genome shine light on human evolution by Azadeh ansari, the Neanderthals genome was sequence from ancient bones and that genome was compared with that of the humans, 1 to about 4 percentage of all the genomes of all living humans in Africa came from Neanderthals. This tells us that Neanderthals and Homo sapiens shared romantic moment "LOL", probably when Homo sapiens left Africa to spread round the world, they might have spread this genome. This prove that this kind of species was very smart and intelligent, up to this point scientists haven't be able to solve the mystery why the Neanderthals suddenly disappeared, although some scientists may have come up with different assumption but until we are certain, let keep up with this curiosity.
