Mutation is the only answer choice that accurately describes a random occurrence producing altered genetic material and inserting new traits into the inherited stream. Lamarckian evolution involves the idea that acquired traits can be passed down to offspring, which is not supported by scientific evidence. Punctuated equilibrium is a theory about the pace of evolution and does not involve the specific mechanism of genetic alteration. Vicariance refers to the splitting of a population by a physical barrier, resulting in the divergence of two groups.
