Accepted Answer

Hi everyone. Let's look at our next question. It says the ancestors of modern humans arose in Africa. It took some time before some species such as Homer Gaster Left Africa and expanded to Southern Eurasia? Why did it take so long for our ancestors to leave Africa? Well, let's look through our answer choices here to see what gives the best explanation, Choice A says because they were not capable of taking long travels by foot. Well, this would not be our explanation here. Um There wasn't any sort of sudden development of extra long travel capability at any time. They were capable of long traveling by foot. So that would not be our answer choice choice be said because they will not leave their elders behind. All this is isn't anything we have any way of knowing about ancient humans based on archaeological records. So we wouldn't have that as a strong explanation for this choice C says, because there were lots of predators around. Um Well, there weren't any specific barrier of predators for humans to move into this area. Uh So that's not our explanation, choice D says because of the extensive arid environments of Northern Africa and the Middle East and that is indeed a huge barrier to travel by foot. Um large deserts, large arid environments where it would be extremely difficult to find enough water and food to sustain such a long journey. And it wasn't until there was climate shift and greening of some of these areas that humans began to move out of Africa and expand into parts of Southern Eurasia? So why did it take so long for answers to leave africa choice? D because of the extensive, arid environments of northern africa and the Middle East? See you in the next video.
