Question

what was the result of penguins not using their wings​

Answer 1

Answer:

Their bodies are streamlined as if for flight, so they still cut cleanly through the water. But water is much thicker than air, so their wings are shorter and stiffer than a normal bird's wings. In fact, penguins are the only birds that are unable to fold their wings.

Answer 2

$\huge\bold\pink{Answer}$

A popular theory of biomechanics suggests that the birds' once-flight-adapted wings simply became more and more efficient for swimming and eventually lost their ability to get penguins off the ground. More efficient diving, on the other hand, increased the opportunities to forage for food at depth.
