Question 15 1 point The theory of continental drift hypothes

Question 15 (1 point) The theory of continental drift hypothesizes that the con as have slowly moved apart from one another aner originaly being a single landmass. can be found on in both South America and in Africa. Considering these continents were once connected, which ofthe following statements is most O isopatric speciation occurred within 75 milion years of the continental separation O monkeys exhibited fewer genetic differences from one another before the continents separated O modern-day monkeys are larger than those existing when the continents were connected O the separation of the continents caused a mass extinction event O modern-day monkeys on both continents are reproductively compatible Save Page 15 of 32 Previous Page Next Page Go to Submit Quiz Save All Responses

Solution

Please find the answers below:

Answer 1: Choice 1 (The information suggests that due to geographical sepeartion of the monkeys, these animals can be found in both north and south regions of a big continent. This does not mean that these monkeys are reproductively incompatible to each other but deciphers that although these animals were geographically separated, they acclimatized very well to their respective residences and fluorished at both north and south of the continent. This kind of speciation is called isopatric speciation where individuals of a species are separated from others due to geographical changes)

Answer 2: Choice 5 (the information in the question states that brain cannabalism is associated with spreading of Kuru disease in some tribes. Since this disease is not common in other isolated tribes, the information suggests that the tribe in which Kuru disease has become common might be transferring genes across their generations which suffere from the disease. Importantly, these tribes are unable to transmit this disease in individuals of other tribes since they lack contact. Also, the tribes which are resistant to this disease have higher chances of survival and hence their population size increases.)
