Even though the ostrich is a flightless bird, ostriches still possess wings that stretch approximately two meters across when fully extended
Scientists speculate that when dinosaurs became extinct some of the birds that lived during that time became land dwellers since
they were able to consume the food that the dinosaurs once ate. Over time, these species grew larger and heavier. Eventually, the
ostrich species became too big to fly.
The wings found on ostriches are known as
OA. analogous structures.
OB. symmetrical structures.
OC. homologous structures
OD. vestigial structures
