In the study of human evolution, scientists define modern in terms of: a designated time frame between the upper and lower paleolithic. traits like large browridges, large nasal sinuses, and a large masticatory complex. a series of anatomical traits that distinguish cro-magnon features from neandertals. a series of distinctive anatomical traits that contrast with archaic traits from earlier hominins.

The correct answer is a series of distinctive anatomical traits that contrast with archaic traits from earlier hominins.

The study of human evolution focuses on the events which led to the development of the human species Homo sapiens as we know it now. The group of hominins includes the modern humans, extinct human species and our immediate ancestors. Earlier hominins possessed some characteristics which are distinctive from the modern humans.
