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

 a)  a series of anatomical traits that distinguish Cro-magnon features from Neandertals.

Neanderthals (Homo neanderthalensis) were first discovered in Germany in 1856 and are believed to emerged between 100,000 and 200,000 years ago.

Significant differences found in the human and Neanderthal includes: 1) their DNA, 2) the brain of a Neanderthal had a raised larynx and was also bigger, and  3) Compared to modern humans, Neanderthals had bigger and muscular body but with shorter legs.

Cro-magnon is the earliest known Western European example of our species who lived  35,000 and 10,000 years ago. They are believed to be actually modern in every anatomical respect. They are much like us.

Neanderthal and Cro-magnon were believed to overlap in Europe for a thousand years but long-term interbreeding was not seen. 

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.
