Introduction: In taxonomical order, primate members belong to animal groups. They are different from mammals and found all over the world. They have a unique combination of traits. The dental pattern of primates are different from others. They possess forward-facing eyes and grasping hands and feet.
Answer to Problem 1SQ
Correct answer: c.
Explanation of Solution
Reason for the correct answer:
According to the angiosperm radiation hypothesis, the availability of fruits and flowers are acquired by primates with the help of visual acuity and grasping hands. This is because of the spread of angiosperms in the early Cenozoic. Thus, this hypothesis specifically linked with the evolution of primates.
Option c. is given as “angiosperm radiation hypothesis”.
Hence, the correct answer is option c.
Reasons for incorrect answers:
Option a. is given as “arboreal hypothesis”.
The arboreal hypothesis explains the evolution of primates based on their unique adaption to living on trees. Therefore, option a is incorrect.
Option b. is given as “visual predation hypothesis”.
This hypothesis reveals the characters of primates are an adaptation to prey on small insects and animals. Therefore, option b. is incorrect.
Option d. is given as “gymnosperm radiation hypothesis”.
There is no gymnosperm radiation hypothesis that exists for the evolution of primates. Therefore, option d. is incorrect.
Hence, options a., b., and d. are incorrect.
Thus, the angiosperm radiation hypothesis specifically links the evolution of primates.

A. The islands only formed after Homo luzonensis became extinct, so Neanderthals must have put them on the island B. The islands were a few miles apart, and Homo luzonensis would have needed to either float by grabbing on a tree or make a raft C. The islands were a few miles apart, and Homo luzonensis clearly had to learn how to fly to get to them D. The islands were volcanoes when Homo luzonensis was alive, so it's unexpected that they were therearrow_forward
