Answer:
I hope the below helps!
Explanation:
Scientists have noticed similarities between a bat's wings and a dolphin's flippers.
Fossil records also show that the 2 animals have the same/similar skeletal elements. These skeletal elements have evolved into different shapes and sizes based on their function. For example, the flipper of a dolphin is adapted for swimming and the wing of a bat is adapted for flying.
This evidence shows that the 2 species are distantly related and share a common ancestor.
