Bankruptcy Quote by Stephen Jay Gould
“[T]ruly grand and powerful theories [...] do not and cannot rest upon single observations. Evolution is an inference from thousands of independent sources, the only conceptual structure that can make unified sense of all this disparate information. The failure of a particular claim usually records a local error, not the bankruptcy of a central theory. [...] If I mistakenly identify your father's brother as your own dad, you don't become genealogically rootless and created de novo. You still have a father; we just haven't located him properly.”

Scientific theories must be supported by many independent observations; a single error doesn't invalidate the whole framework.
In simple terms: Theories need many pieces of evidence; one mistake isn’t fatal.
Check multiple sources before dismissing a theory.
