answer is option d just before world War two
Geographic isolation and different living conditions.
Explanation:
Both the Neanderthal and the Homo sapiens shared the same ancestor, the Homo erectus. The Homo erectus managed to spread from Africa to Eurasia. The populations started to become geographically isolated from each other, and over time this caused speciation.
The Homo erectus from the far East, with the one from Europe, or the one from Africa, didn't had contact. This was due to big distance and natural barriers. Gradually this species was evolving, and because of the different living conditions and the geographic isolation at different places it started to develop different characteristics. This has led to evolution of different species over time, with the Neanderthal evolving in Eurasia, as well as the Denisovan Man, while in Africa it was the Homo sapiens that emerged.
Answer:
Local collaborators
Explanation:
Germany had a large, strong, well trained, and well equipped army, but that still was not enough so that they can be all over Europe and control everything themselves. In order to be able to keep things under control and their goals to be achieved, the Germans depended a lot on local collaborators. Some of those collaborators were from the occupied countries, while some were smaller countries that had allied with the Germans. Some of the countries that were helping the Germans in their goals were the Hungarians, Bulgarians, Lithuanians, Italians, Albanians, Croatians. All of them were managing to keep control with their military forces on local level, which was easing things up a lot for the Germans to make further expansion and get involved into some battles.
