who is credited with linking characteristics of living organisms to past ancestors
Common descent Universal common descent through an evolutionary process was first proposed by the English naturalist Charles Darwin in On the Origin of Species (1859), which concluded: "There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved."[9]
