The contraction of auricular muscles around the ear produces a range of motions in the ears of domesticated animals as well as t
he macaque monkey and most other monkeys. Thanks to these muscular motions, the ears act as antennae and can be used to sense danger and locate prey. Humans and other primates such as the orangutan and chimpanzee have ear muscles that are minimally developed and non-functional. How are these vestigial ear muscles an example of natural selection?

B) Most primates are not victims of predators and they are not predators themselves so they do not need this trait.
C) In most primates, the inability to move the ear has been replaced by the ability to stand upright on two legs.
D) A muscle attached to the ear that cannot move the ear has no function.
The correct answer is letter C, in most primates, the inability to move the ear has been replaced by the ability to stand upright on two legs. This is because movement was much of a need to these primates than hunting for food. They needed to be agile to locate specific places where sources of food are abundant.
In most primates the inability to move the ear has been replaced by the ability to turn the head on a horizontal plane as well as having peripheral vision. The function of the movable ear has been replaced by the function of other parts of the muscular and sensory systems.
Most animals are well adapted to their biotic and abiotic conditions due to behavioural, physiological or structural adaptations that increase their chances of survival and reproduction. I looked it up for you
<span>The type of diagnostic test that is used to tell how much protein is being excreted by the kidneys and to estimate the filtration abilities of the kidneys is a twenty-four-hour urine collection. This test collects urine over a 24-hour period to be sent to a lab for analysis, and the components of the urine sample can be used to detect certain diseases.</span>
