A. It was intermittently occupied by early humans during the waves of migration out of Africa. C. It is the crossroads of Western Asia, the Eastern Mediterranean, and Northeast Africa. D. It is where Homo sapiens first encounter archaic humans outside of Africa.

Thick forests make the sites difficult to find. C. They only followed a coastal route so the evidence has washed away. D.

Most of the water was still trapped in continental glaciers. B. It was not lower, but higher compared to present day levels. C. Most of the water was held up in the clouds. D. All of the above.

A. Most of the water was still trapped in continental glaciers.

What role did Neanderthals play in human migration through southern Arabia? A. Neanderthals developed similar tools to the Arabian descendants that created Emiran tools in the Middle East. B. Neanderthals lived in southern Arabia alongside humans. C. Humans followed Neanderthals through southern Arabia to the Levant area. D. Neanderthals interbred with humans in southern Arabia.

A. Neanderthals developed similar tools to the Arabian descendants that created Emiran tools in the Middle East. Neanderthals did develop similar tools to the Arabian descendants that created Emiran tools in the Middle East and it is possible that humans were influenced by the Neanderthal design. However, Neanderthals did not live alongside nor interbreed with humans in southern Arabia (they did in the northern Levant region). Humans did not follow the Neanderthals through southern Arabia.

The evidence suggests that humans co-existed with large animals for between 20,000 to 25,000 years after first arriving in Australia, which meant that: A. humans didn't immediately wipe these animals out upon discovering Australia. B. humans immediately wiped these animals out upon discovering Australia.

A. humans didn't immediately wipe these animals out upon discovering Australia.

Which statement is false? A. The Arabian Peninsula dried out dramatically 75,000 years ago. B. The Arabian Peninsula was a vast desert 125,000 years ago. C. Early humans established settlements in southern Arabia 100,000 years ago. D. The design of tools defined the transition between archaic and modern humans.

B. The Arabian Peninsula was a vast desert 125,000 years ago. The Arabian Peninsula was a not vast desert 125,000 years ago, it was a 'green oasis.' Early humans did establish settlements in southern Arabia and lived there for 50,000 years. Then the Arabian Peninsula dried out around 75,000 years ago and the groups in this area then migrated north to the Levant area in the Middle East where they crafted Emiran tools that defined the transition from archaic to modern humans.

Why was the distance traveled by the first humans who migrated into SE Asia and into Australia shorter compared to the distance they would travel today? A. More land was exposed during the ice age due to lower sea level. B. Because of the ice age, more water was trapped as ice in glaciers. C. Both A and B. D. None of the above statements are true.

C. Both A and B.

Which statements are true? A. Neanderthals died out because they were primitive and inferior to Homo sapiens, lacking any social organization or ability to use tools, fire, art, and language. B. All genes that are inherited from Neanderthals are harmful to modern humans. C. Genes that some humans inherited from past interbreeding with Neanderthals can control susceptibility to certain diseases. D. Neanderthals had complex cognitive abilities and behaviors possibly including rituals.

C. Genes that some humans inherited from past interbreeding with Neanderthals can control susceptibility to certain diseases. D. Neanderthals had complex cognitive abilities and behaviors possibly including rituals.

Why do scientists study Neanderthals (Homo neanderthalensis)? A. Neanderthals were basic and unsophisticated. B. Neanderthals are still alive today. C. Neanderthals are distant cousins and their behaviors and evolutionary history hold clues to our own identity as Homo sapiens. D. Homo sapiens evolved from Neanderthals. E. Neanderthals never crossed paths with Homo sapiens.

C. Neanderthals are distant cousins and their behaviors and evolutionary history hold clues to our own identity as Homo sapiens

How did climate affect the survival of Homo sapiens versus Neanderthals? A. Homo sapiens were likely more successful in utilizing scarce glacial food resources as compared to Neanderthals, thus outcompeting and slowly absorbing them into their species. B. Homo sapiens were better adapted to a colder climate because they had large nasal chambers that helped warm and humidify the cold and dry air. C. Homo sapiens had higher reproduction rates and resulting faster migration speeds which allowed Homo sapiens to move away from areas that underwent a rapid decline in food resources due to rapid past climate changes and re-populate elsewhere. D. A and C are correct. E. All answers are correct.

D. A and C are correct.

Which statement is false? A. Green Sahara periods allowed for a North African corridor and migration out of Africa. B. Green Sahara periods can be identified through cave paintings and fossils of hippos and crocodiles in North Africa regions that are now in dry desert climate (e.g. the Sahara Desert). C. Migration out of Africa through the northern and southern routes occurred in waves. D. Green Sahara periods can be identified through dust records from marine sediments. E. Green Sahara periods were caused by stronger Northern Hemisphere seasons (warmer summers) and stronger African monsoon. F. Homo erectus was much larger than Homo sapiens and was extinct when Homo sapiens emerged.

F. Homo erectus was much larger than Homo sapiens and was extinct when Homo sapiens emerged.

100,000 years ago when humans were migrating through Arabia, the monsoons were weaker which meant that Arabia was wetter and greener than today. True or False?

False

Migration from Africa to Arabia occurred 75,000 years ago when Arabia had lush interconnecting rivers and lakes. True or False?

False

Migration through Arabia towards Asia occurred along the Oman coast where there were plentiful resources. True or False?

False

Around 100,000 years ago archaic humans (the variety of Homo species before modern humans) first left Africa. True or False?

False There is evidence that archaic humans first left Africa 2,000,000 years ago. Homo sapiens first left Africa approximately 100,000 years ago, though migration on a mass scale began only 60,000 years ago.

Monsoons lead to more rainfall when there is strong solar radiation on land (strong summers) creating a low pressure system which pulls in ocean winds. True or False?

True
