Throughout this week and last week you start to see differences and similarities between the middle and upper paleolithic periods. In the Upper Paleolithic period species started to develop more. They put more thoughts into what they were doing. They had to evolve to the surroundings and situations they were in. In the Upper paleolithic period they worked more toward improving their technology. They started to do things that no other species has ever did. Their way of living was changing for the better. Upon their changes you start to new developments from past times.
In the Middle Paleolithic period you see the development of stone tools. Species had to find a better to hunt and make a living. They developed tools and was the evolution of the lower paleolithic period. During this time it was focused on Mousterian and Aterians. Mousterians was associated with Neanderthals while Aterian was mostly associated with modern humans. One similarity you see between the middle and upper Paleolithic is the burials. In the Middle Paleolithic species started to bury individuals who were dead. Later in time you see neanderthals doing the same. However, a differences between the two is that the Upper Paleolithic species started to lay flowers. Another similarity you see is the overlapping.
The Upper Paleolithic was the oldest. Ranging from 50,000 to 10,000 years ago. In this era their was a huge upgrade as mentioned before. In this era species started to sort of combine. More and more tools started to develop and improve. There was more and more food coming about. As new things were developing species started to change their way of living. Groups started to increase because of the overlapping that was happening.
Something that was different was the tools. Tools in the upper paleolithic had to change because of the evolution that took place. They had to make tools that would better fit their environment. In the Upper Paleolithic period there were four types of tools. The first was Arignacian. Aurignacian or the aterian tool was cause of the first painted caves. The second one was Gravettian. Gravettian famous tool was the Venus figurines. Gravettian was also associated with big-game hunting. The third is Solutrean and was associated with Southwertern Europe. The fourth one is Magdalenian and was known for having basic tools.
I agree that as the environment change it accounts for differentiation of tool traditions. As one thing changes another has to change with it. Both grounds would have to equal out.
