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.

membranes are made of lipids because substances that dissolve in lipids enter cells more rapidly than lipid-insoluble substances
What is the basis of grouping animals?

What two testable assumptions were the basis for Darwin's hypothesis about the evolution of the Galapagos finches?
The two testable assumptions were that 1) each island had its own distinct finch population that were closely related but adapted to their specific environment, and 2) the finches had originally migrated from South America and gradually evolved on the islands to become different species based on their unique diets and habitats.
What would be a testable hypothesis on the topic born gay vs learned behavior?
A testable hypothesis could be: "Individuals who identify as homosexual will exhibit consistent patterns of brain activity in response to sexual stimuli compared to heterosexual individuals, supporting the hypothesis of a biological basis for sexual orientation."
What is sound hypothesis?
A sound hypothesis is a statement that proposes an explanation for a phenomenon based on existing knowledge and observations. It should be testable, specific, and have clear predictions that can be verified through experimentation or observation. A sound hypothesis forms the basis for scientific inquiry and guides the research process.
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.
What possible explanation or answer to a question is called?
A possible explanation or answer to a question is called a hypothesis. In scientific research, a hypothesis serves as a testable prediction that provides a basis for experimentation and investigation. It is formulated based on existing knowledge and observations, guiding researchers in exploring and understanding phenomena.

It must be testable in order to be found true or false. -Apex

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!
A hypothesis is a statement that can be?
To be of any use to science, a hypothesis must be able to be tested. For instance, I might have a hypothesis that there is a civilization of giant butterfly people living in another galaxy. If I have no way to test this idea, then it really isn't a hypothesis. It would just be a wild guess.
What is the term hypotheses?
Hypotheses is the plural form of hypothesis, meaning a supposition made on the basis of limited evidence as a starting point for further investigation; in philosophy, a proposition made as a basis for reasoning.
What is a hypothesis is?
A hypothesis is a proposition made as a basis for reasoning, without any assumption of its truth. It is an unproved theory or conjecture that may be the basis for experimentation.
