Show summary

Biologist: Humans have five fingers because we descended from a fish with five phalanges in its fins. ███████ ███ ██████████ ██ ███ █████████ ███ █████████████ ██ ███████ ██ ██ ████ ██ ████ ██████ ████ ███████ █████ ████████ ███████████████ █████ ███ ███ █████ ███ ██ ██████ ███ █████████ ████ █ ████ ████ ███ █████████ ██ ███ ████ ███ ███ ███ ███████ ██ ████ █████ ████ ██ █████ ██ ████ ██ ███████ ████ ████ ██████████████

Summarize Argument

The biologist concludes that humans would be equally content with having six fingers per hand if we had descended from a fish with six fin phalanges rather than five. This is because a hand configuration with six fingers is no more or less useful than one with five fingers.

Notable Assumptions

The biologist shifts from usefulness (in the premise) to contentment (in the conclusion) without justification. This means that the biologist assumes that usefulness is the only relevant factor to how content we are with our hands.
