Darwin made bold assumptions about heritable variation, the age of Earth, and relationships among organisms.
First, in order for beak size and shape to evolve, there must be enough heritable variation in those traits to provide raw material for natural selection.
Second, differences in beak size and shape must produce differences in fitness that cause natural selection to occur.

Why must an hypothesis must be testable?
If a hypothesis does not generate any observational tests, there is nothing that a scientist can do with itRead more: Explain_why_a_hypothesis_must_be_testableANS2:If an hypothesis is not testable, it cannot be provable false. If it cannot be provable false it cannot be supported. If it cannot be supported, it adds nothing to science. An hypothesis is a "no-win" proposition. You need to try to prove it false. That being the case, you either prove it false (lose) or you fail to prove it false (lose). Failing to prove an hypothesis false is the basis for supporting it.

Is a theory a hypothesis that hasn't been proven true?
The question is stated incorrectly. It should ask: "Is theory a hypothesis that HAS been proven true?" (my emphasis) 1) A hypothesis in science is merely a conjecture put forth to provide a basis for further debate and to conceive research and experiments. It is a working guess, not an untested theory. 2) A theory is a comprehensive set of explanations for known phenomena. It must make testable predictions that can be confirmed or reputed. 3) When you make explanations without testable predictions, it is called philosophy. To sneer "That is just a theory" is to misunderstand just how much effort goes into producing a testable theory. ## So the answer is No.
In science does the hypothesis have to be testable?
A hypothesis is often used as a starting point to define the scope and objectivity of performing an experiment. A hypothesis is a statement that implies there is insufficient evidence to support an idea or an explanation of an observation or principle. It is a statement of unproven fact, sometimes just a guess that is tentatively accepted as a basis or foundation for further investigation. If a hypothesis is proven to be correct beyond reasonable doubt, it becomes a theory and is generally accepted by the scientific community. I hope this answered your question!
