Description
“The theory of organic evolution involves these three main ideas: (1) Living things change from generation to generation, producing descendants with new characteristics. (2) This process has been going on so long that it has produced all the groups and kinds of things now living, as well as others that lived long ago and have died out, or become extinct. (3) These different living things are related to each other.” Mere change within a basic type of living thing is not to be regarded as evolution. That is simply variety, as we can observe among all plants, ani- mals and man. For instance, there are various sizes, shapes and colors of cats, but such is only variety and in itself does not constitute organic evolution.
