Lamarck proposed common descent, whereas Darwin rejected it Lamarck relied on genetic drift, whereas Darwin relied on mutation Lamarck proposed Mendelian inheritance, whereas Darwin proposed blending inheritance Lamarck emphasized changes acquired by individuals, whereas Darwin emphasized changes in frequencies of heritable variants in populations

Correct Answer:

Lamarck emphasized changes acquired by individuals, whereas Darwin emphasized changes in frequencies of heritable variants in populations
