Question 2

In 2010,Dr.Svante Pääbo published research indicating that all modern ethnic groups,other than Africans,carry traces of Neanderthal DNA in their nuclear genomes.His earlier work indicated no overlap between Neanderthal mitochondrial DNA and that of Homo sapiens.Which of the following is NOT a likely possible hypothesis that could be supported by this information?

Accepted Answer

A)  The shared nuclear DNA could be a remnant of DNA from a common ancestor shared by Neanderthals and Homo sapiens.
B)  The shared nuclear DNA could be the result of interbreeding between male Neanderthals and female Homo sapiens.
C)  The shared nuclear DNA could be a remnant of DNA from Homo erectus,one of the most recent species since Australopithecus.

Question 13

If your mitochondrial DNA was sequenced and compared to the sequence of mitochondrial DNA isolated from your mother's paternal grandmother (the mother of your mom's dad) would you expect to see a significant match to yours and why?

Accepted Answer

A)  No,there would not be a significant match because my mitochondrial DNA was inherited from my mom who inherited it from her mom.
B)  No,there would not be a significant match because my mitochondrial DNA was inherited from my dad who inherited it from his mom.
C)  Yes,there would be a significant match because I inherited my mitochondrial DNA from my dad who inherited it from his mom.
D)  Yes,there would be a significant match because I inherited my mitochondrial DNA from my mom who inherited from her dad.

Question 20

You are a researcher excavating a site in a cave in Israel.There are many layers of sediment and primitive artifacts (flint tools for cutting and scraping) from ancestral Homo species within the cave.As you work your way deeper and deeper through the layers,you notice that artifacts in the deeper layers (laid before 350,000 years ago) do not show any signs of having been exposed to fire.Artifacts in layers less than 350 tya show rapidly increasing evidence of exposure to fire.Your colleagues working in nearby caves and caves scattered around the eastern Mediterranean Sea have found similar evidence dating in the same time frames.The evidence is also consistent with that of European sites.What does this suggest about the use of fire by ancestral humans?

Accepted Answer

A)  Ancestral humans who had migrated to areas around the eastern Mediterranean Sea and Europe very likely learned to control and use fire around the same time (about 300,000 to 350,000 years ago) ,and they became increasingly good at it.
B)  Ancestral humans (about 200,000 years ago) were simply using fire they obtained from lightning-sparked wildfires;they did not make or maintain their own fires.
C)  Ancestral humans could not have migrated into climates cooler than those found in Africa until about 150,000 years ago because they had not yet figured out how to use fire before that time.
D)  The hominins occupying the caves,making and using fire must have been modern Homo sapiens because no other human ancestors were still surviving 300-350 tya and no other human ancestors were ever able to use fire.
