1. Much of the behavior of all primates is learned. Nonetheless, we have suggested many times that primate behavior has been shaped by natural selection. How can natural selection shape behaviors that are learned

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
