生物进化被定义为持续过程，其中人或动物或任何其他生物的遗传特征发生变化。 生物进化是一个非常缓慢的过程，需要时间才能看到变化。 它曾经发生在后代。 当这个过程完成时，它被称为繁殖成功。 它可以由自然过程，近亲繁殖，繁殖分离或突变引起。自然选择是具有某些特征的实体的存在和再现的差异程度。 自然选择作用于有机体的可见特征。 生殖隔离是一种具有各种障碍的系统，可确保两个不同物种的实体不交配产生后代（Koonin，2011）。

Biological evolution is defined as the continuing process in which there is an alteration in the genetic characteristics of a person or an animal or any other living being. Biological evolution is a very slow process and it takes time for the changes to be visible. It used to happen in the successive generations. When this process is completed it is known as reproductive success. It can be caused by natural process, inbreeding, reproduction isolation or mutation.Natural selection is the degree of difference in existence and reproduction of entities with some characters. Natural selection acts on visible characteristics of organism. Reproductive isolation is a kind of system of various barriers which make sure that the entities of two different species do not mate to produce offspring (Koonin, 2011).
