-Refer to the paragraph on Brown et al.and Morwood et al.It is speculated that H.floresiensis and H.sapiens may have lived on Flores concurrently.Suppose researchers obtained mitochondrial DNA samples from the H.floresiensis remains,amplified a 1000-base-pair sequence via PCR,and compared it to that of several currently living H.sapiens native to Indonesia,North Africa,and North America.Also suppose H.floresiensis were found to differ from the average Indonesian H.sapiens in 28 base pairs,from the average North African H.sapiens in 51 base pairs,and from the average North American H.sapiens in 53 base pairs,while two randomly selected H.sapiens differed from each other in an average of 21 base pairs.What would you surmise from these data?
H)floresiensis and H.sapiens probably did not live on Flores concurrently.
H)floresiensis and H.sapiens probably lived on Flores concurrently,but did not interact.
H)floresiensis and H.sapiens probably lived on Flores concurrently,and H.sapiens killed and consumed H.floresiensis.
H)floresiensis and H.sapiens probably lived on Flores concurrently,and interbred to some degree.

Quizplus · Accepted Answer

The genetic differences between H. floresiensis and H. sapiens are relatively small, suggesting the possibility of interbreeding if they lived concurrently.
