Heredity: Not a Blending But a Preservation
Fleming Jenkins incorrectly posited that natural selection couldn't operate because he believed in a flawed concept of blending inheritance, where traits would intermingle and eventually fade into uniformity. However, Mendel's work demonstrated that heredity is based on discrete genes that do not blend but are instead passed intact from parent to offspring. This understanding reveals that genetic variation is preserved across generations rather than diminished, refuting Jenkins' argument against natural selection.
