Question
Which of these structures would be used for grasping?
Open in App
Solution
The correct option is A 1
Homologous organs are the organs that are similar in morphology but they perform different functions e.g., Forelimbs of frog, reptile, birds, and mammals., where we observe leaping in the frog, crawling in reptiles, flying in birds, running and grasping in mammals.Even though the bone structure in these limbs of the mammals is very similar, the function of the limb itself is very different. The homologous limbs can be used for flying, swimming, walking, or everything humans do with their arms. These functions evolved through natural selection as the common ancient ancestor underwent speciation to make all of the diversity we have on Earth today.So, 1 is the hand of a human used for grasping. Thus, option A is correct.
