In the 1930s, scientists unified natural selection and genetics into theMultiple choice question.genetic variation synthesis.heritable synthesis.modern evolutionary synthesis.theory of uniformitarianism.

The modern evolutionary synthesis connects natural selection andMultiple choice question.artificial selection.discoveries that fill gaps in fossil record.genetic variation that arises by mutation.the ideas of spontaneous generation.
