Homo neanderthalensis.
Neanderthals were the previous to Homo Sapiens in the chain of evolving hominids. They appeared approximately 300000 years ago, 150000 years before modern humans. These approximate numbers were adopted at the end of 20 century. Later they were shifted backwards. At the time of coexistence their experience was definitely larger. What is necessary to underline, Neanderthals were specifically European hominid. They lived in Asia too, but the main habitat was West, South, Central, and East Europe. The climate here is colder than in Tropical Africa so this species needed to adapt. These changes proceeded along 2 ways.
First – modifications of the organism. Heat production is proportional to the volume; heat loss – to the surface area. For the ball, the ratio of loss to production will be inversely proportional to its size. Also, it will grow for long objects. In the cold climate, it is more profitable to be large and round; in the hot – small and elongated. Neanderthals had wider skeleton and stronger musculature. Northern climate stimulated growth of hairs. The brain was larger.
Sapiens vs. neanderthal comparison.
Its rear part was enhanced because it contains visual areas and Neanderthals lived in dark caves and the North receives less insolation. Also they had elongated skulls. This relates Neanderthals with Paracas people in Peru. Many cultures worldwide tried to deform their sculls, but Paracas had different bones. Their scull is definitely not that of Neanderthals, but it could evolve from that. Also let's ask, why different peoples exposed their children to such a torturous procedure? Obviously, they believed that it is useful. Probably they remembered somebody with such a head who was more clever and skilled than they were.
Second – behavioral changes. Protection from the cold forces search for natural dwellings such as caves or building artificial ones. Initially historians deemed that people began to build villages with the introduction of agriculture and these villages later grew into towns. Later discoveries showed that the first towns emerged simultaneously with villages and even before agriculture. Neanderthals created their dwellings out of animal skins, large bones, tusks or horns, and stones. Building, making clothes, hunting requires more and more sophisticated tools. Neanderthals even knew technology. They attached the pike to the shaft with a glue.
Neanderthals lived in small collectives and probably used a language for communication. To what level could their society rise? Neanderthals disappeared approximately 30000 years ago. How did it happen? Several hypotheses exist. Their population could gradually decline by itself. They could be pushed aside or even actively terminated by modern humans. This work promotes another version. Neanderthals mixed with Homo Sapiens, formed the ruling class over them, and gradually dissolved in the new generations.
The Near East plays some special role in religion and human history. These places are considered sacred because something important happened there in the past. Levant aka the Mediterranean Corridor is the point of most probable contacts between Neanderthals and Homo Sapiens. Archeology reveals that this area changed hands. The time table correlates with periods of glaciation in East Europe. The 2 last occasions were 170 – 125 and 110 – 70 Ka. Neanderthals lived in the Near East before 100 Ka. Circa 130 and till 80 Ka they were replaced by Homo Sapiens. Neanderthals returned to live from 80 – 55 Ka. From 70 Ka, the second expansion of modern humans started. Obviously, as glaciers retreated, both species moved to the North in search for new territories. The reverse motion was more complicated. In both cases, mixing of populations was possible.
