The fossil that would prove evolution, forever one dig away from being found.
means A hypothetical intermediate form or piece of evidence that would connect two stages of a chain — most famously the undiscovered fossil ancestor bridging apes and humans.
from The phrase rides on the old 'Great Chain of Being,' the medieval-to-Enlightenment idea that all creation forms one continuous ladder from minerals up through plants, animals, humans, angels, to God — with no gaps allowed. When Darwin's theory of evolution took hold in the 1800s, that chain got reimagined as a branching tree of descent, and people went hunting for the literal fossil links joining one rung to the next. 'Missing link' became shorthand for the connector between ape-like ancestors and modern humans specifically — popularized in the wake of evolutionary debate, though Darwin himself spoke more cautiously of transitional forms. The term stuck as a figure of speech long after paleontology moved past the ladder metaphor entirely.
- origin
- Term predates Darwin, from 18th-century great chain of being
- irony
- Every fossil found creates two new gaps beside it
- science status
- Biologists hate the phrase, evolution is a bush, not a ladder
- pop culture
- Often misapplied to Bigfoot, nothing to do with ape ancestry
