I'm Only Half Way To The Moon

Why does a tree or a plant Have more DNA than me Am, I any less evolved? Then a plant or a tree! So we're all coded. By 4 letters A, C, T, and G But, where am ‘I' on- The amino acid chain, me! What part of the codon wheel? Do I belong, too…? So proteins are building blocks. Bricks in the wall, a menu! So, on their ladder, I've got- 6,000,000,000 'rungs' of DNA That if stretched like snot Would, reach halfway to the moon. But still 'I' isn't as evolved- As a plant or a tree We humans, all 99% alike So laugh you're related to me.
