species are genetically similar
Reason:protein synthesis is regulated by the sequence od DNA in the nucleus of the living being )plant or animal), and the similarity of proteins, is due to the similarity of the genes that produce transcription of messenger DNA

Species are genetically similar.

The others may well be an effect of similar proteins, rather than a cause.
