All animals and plants share similar cell structures with a cell membrane, nucleus, mitochondria, lysosomes, endoplasmic reticulum, Golgi body, and cytoplasm. Plant cells also have a cell wall and chloroplasts. They also share the same genetic code and a common ancestor some 1.6 billion years ago.
Is there anything universal that all animals share? Or even anything that all animals and plants share, including humans (physically not mentally)?
