How is the theory of evolution an example of a scientific theory?

Scientific method is an empirical method of knowledge acquisition, involving careful observation, formulating hypotheses based on such observations, testing deductions drawn from the hypotheses, and refinement or rejection of hypotheses based on the results of the tests.ext we have to know what “theory of evolution” we’re talking about. Let’s begin with the theory proposed by Charles Darwin in the Origin of Species.

I don’t know what “No assumptions here” in the question details is supposed to mean. Making hypotheses is part of the scientific method. Maybe it means that a hypothesis is assumed subject to verification, while an assumption is an axiom not subject to test. The scientific method makes testable hypotheses but never makes firm assumptions.

Darwin made a lot of observations. Then he made two hypotheses:

The observed variation among individuals can accumulate to produce all the differences we observe among species.

The effect of these variations on the ability of a living entity to survive and reproduce preserves some variations and eliminates others.

The heritability of variations was essential to the theory, but it was an observed fact, not an assumption or a hypothesis.

biology is the study of life. it is the study of living organism.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
