Parts
Explanation
This comic imagines a conversation between God and Evolution about the design of animal bodies, highlighting the absurd anatomical compromises that resulted from evolutionary constraints.
God opens by asking about "design constraints on animals." Evolution explains the basic plan: legs and arms for movement on four limbs, a subset repurposed for manipulation (as with primates). God asks where the head goes, and Evolution says "above the torso."
Then the conversation gets complicated. God asks about putting sex parts near the food parts, and Evolution explains that yes, they can do that, but the digestive and reproductive systems will need to share plumbing in some cases, with vasculature routed around various organs. God seems increasingly uncomfortable with the engineering compromises being described.
The punchline comes when Evolution proposes: "Now put the poo parts with the sex parts." This highlights one of the most commonly noted "design flaws" in animal (and human) anatomy -- the proximity of reproductive and excretory organs. God's exasperated reaction underscores the joke: if a designer had actually planned this, it would be considered terrible engineering. The comic uses this as an argument for evolution over intelligent design -- no competent designer would put things together this way, but evolution, working incrementally with existing structures, ended up with these awkward compromises. The final line about needing "4 or 5 more limbs" if they want to avoid this suggests that truly good design would require a complete overhaul.
