Some say that wars of territorial expansion and defense avoided because they cultural in origin. Such human territorial behavior. However, is motivated by both culture and instinct. Territorial instinct can evolve in animal species for some vital resource serves as a “ density-dependent factor”- a factor whose effect on population growth or size in a territory varies with population density. In other words, as a species’ population density increases in a territory, the growing shortage of vital resources such as habitat, food or water incrementally shows its rate of population growth. Eventually, death and birth rates come into balance and population density levels off. Under such circumstances, territorial instinct tends to evolve. Individuals genetically predisposed to defend resource have higher survival rates and thus pass on more genes to the next generation.
Not very species develops the instinct for territorial behavior, however, A species’ populations density could be leveled off not by limited resources by rising levels of emigration, disease, or predation. When such alternative density-dependent factors are paramount territoriality usually doesn’t evolve.
But humans are decidedly territorial. Their war over territory arise from a combination of instinct and culture and can therefore best be avoided by an understanding of how these elements interact.

领土扩张战争基于文化和直觉(??).
2.分论点
Para 1:提出论点:领土扩张基于两个要素,文化和直觉。用动物界举例,如果增长率大,那么生存资源就少了,增长率下降从而平衡。那时领土战争就出现了。
Para 2:不是所有种族都有领土直觉。但过多的人口密度不但可以由资源,还可以有迁徙。疾病。和捕食者决定。
Para 3:但人类是领土型。他们的领土增加从掠夺中来,并且避免上文提到的那些问题。
3.摘抄印象深刻或者觉得优美的句子
Although the neutralino is heavy by normal standards, it is generally thought to be the lightest supersymmetric particle
The best fit to the astronomical observations involves “cold” dark matter, a term that refers to some undiscovered particle that, when it formed, moved sluggishly..
According to calculations of particle synthesis during the big bang, such particles are simply too few in number to make up the dark matter.
