what are these structures an example of?\n○ transitional structures\n○ analogous structures\n○ vestigial structures\n○ adapted structures
Answer
Answer:
C. vestigial structures
Brief Explanations:
Vestigial structures are remnants of organs or structures that had a function in an ancestor but are now non - functional or have reduced function. Whales have pelvic and femur bones which are vestigial as they are no longer used for walking on land like their land - dwelling ancestors.
