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.

What hypothesis did Charles overton make?
membranes are made of lipids because substances that dissolve in lipids enter cells more rapidly than lipid-insoluble substances
On the basis of similar body structures scientists hypothesize the two species are closely related what other evidence would the scientist look forward to support their hypothesis?
To support their hypothesis of close relatedness between the two species, scientists would examine genetic evidence, such as DNA sequences, to identify similarities and differences in their genomes. They might also analyze protein structures and biochemical pathways, as well as fossil records that indicate shared evolutionary history. Additionally, behavioral and ecological similarities could provide further support for their relationship.
What is the basis of grouping animals?
The basis of grouping animals is to classify them. This provides an easy and organized way to study and learn about a species.
What is the fetal membrane that forms the basis of the umbilical cord?
allantois
Why do people yawn when you do?
No one knows for sure but it may have a social interaction basis.
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.
Developing a hypothesis is which step in the scientific method?
Developing a hypothesis is typically the second step in the scientific method, following the observation and question stage. A hypothesis is a testable statement that provides a proposed explanation for the observed phenomena. It serves as a basis for experimentation and further investigation to validate or refute the idea.
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.
What is the educated guess about the outcome of an experiment called?
The educated guess about the outcome of an experiment is called a hypothesis. It is a testable statement that predicts the relationship between variables based on prior knowledge or research. A hypothesis guides the direction of the experiment and provides a basis for further investigation and analysis.
In science a logical explanation for observed facts is called a?
In science, a logical explanation for observed facts is called a hypothesis. A hypothesis is a testable statement that provides a potential explanation for a phenomenon. It can be supported or refuted through experimentation and observation, forming the basis for further scientific investigation. If repeatedly validated, a hypothesis may contribute to the development of a theory.
Why should a hypothesis's be testable?
It must be testable in order to be found true or false. -Apex
What is the proposed answer to a scientific problem?
The proposed answer to a scientific problem is often referred to as a hypothesis. It is a testable statement that predicts the relationship between variables and provides a basis for experimentation. Scientists collect data through observations and experiments to support or refute this hypothesis, ultimately contributing to the broader understanding of the issue at hand. If supported by evidence, the hypothesis may evolve into a theory.
What term describes and educated guess about what the answer to a question might be?
The term that describes an educated guess about what the answer to a question might be is a "hypothesis." In scientific research, a hypothesis is formulated based on existing knowledge and observations, and it serves as a basis for further investigation and experimentation. It is typically testable and can be supported or refuted through data collection and analysis.
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.
