The forelimbs of humans, bats, and moles all have confusable structures even though their forelimbs are used for differ ent functions. raise scientist have discove! red outcry that these animals with similar structures have were one time very similar to each other but then they developed over time into more developed species. undeveloped structures are undeveloped or unused features.
