- All living organisms share a common ancestor
- Nucleic acids were the first living things
- Proteins are a secondary importance of living systems
- The protein composites of all living organisms is the same
- There is redundancy in the genetic code

...at have different functions. These building blocks are still used today and while the organisms have evolved quite dramatically, the basic building blocks, the amino acids, which come from the genetic code remain the same.

- Nucleic acids were the first living things.
This is not correct. Nucleic acids are molecules

- Proteins are a secondary importance ...
