Theory of evolution biochemical similarities - give some arguments supporting and opposing evidence from biochemical similarities among organisms. In layman's terms.

cellular respiration
plasma membranes mitochondria

These are examples that show commonalties with all living things. The reason we can eat is because all living things are biochemically similar, we share the same nutrient stock. That alone is a striking support.

Opposing evidence? I can't think of anything worth mentioning.
