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.
 
        
             
        
        
        
The concept of "total war" refers to a type of armed conflict that is bound by no rules or limitations in terms of who is being attacked, the weapons that are used or the elements of society that will be sacrificed to win it.
Engaging in this type of war can have some benefits, such as:
- There is no need for the government to define its objectives clearly.
- Because of it, there is no accountability between the government and its citizens, which gives them free reign of action.
- Countries with a strong military can use their full power.
However, the costs far outweigh the benefits:
- Increased cost of human lives, from all parties involved.
- The destruction of all civil society.
- Because civil society is so disrupted, government institutions are likely to collapse as well.
- Extremely difficult recovery process, both politically as economically.
- Complete depletion of the country's resources.
- Violation of human rights and the laws of just war.
- Closes the door to any peaceful solution.
There is rarely, if ever, a situation in which a total war provides benefits that would outweigh the costs of it, or that would not be achieved through some other means.
