Ghostly Relative

The gene of one of the proteins got into the human genome about 150,000 years ago as a result of crossing with a "ghost" species of hominids. Our common ancestors separated 1.5−2 million years ago.

Ribosomes were imprisoned for self-reproduction

They spend 20% of their "working time" on the synthesis of ribosomal proteins and RNA polymerase molecules, which synthesizes new ribosomal RNA molecules.
