Difference between evolution and progress |
| Answer» Even though the mechanism of evolution involves improved abilities in a species, it does not mean that evolution is progressive. Natural selection does not produce perfect organisms suited to the surrounding environment.\xa0The surviving species merely possess a conducive range of traits. Hence, evolutionary change does not automatically ensure persistence of particular species. For example – mosses, fungi, shark and crayfish have undergone little physical change over the passage of time. It did not render those unsuited for its surrounding environment.\xa0The discourse of progress is not entirely compatible with evolution. With climate and topological changes, the existing favourable traits in an organism may become poorly suited for survival with massive changes in environment.\xa0 | |
