Explanation
This comic addresses the classic philosophical "Teleporter Problem" -- the question of whether a teleporter that destroys your body and reconstructs it elsewhere is actually killing you and creating a copy. A person in a Star Trek-like setting asks "Do I die when the teleporter switches on?" and a scientist responds with: "Same gametes. Same phenotype. Same number of agents. Model works the same."
The caption reads: "Population biologists don't understand the Teleporter Problem." The humor comes from the disconnect between individual identity (which is what the teleporter problem is really about) and population biology, which studies organisms at the level of populations rather than individuals. From a population biologist's perspective, if all the genetic and phenotypic traits are preserved, nothing has changed -- the "model works the same." The comic satirizes how different academic disciplines can completely talk past each other when approaching the same philosophical question, because their frameworks operate at fundamentally different scales.
