“I’ve posted a number of these articles about marvels of design which occur throughout nature yet no matter how many examples are given evolutionists still insist they are just products of blind random chance … how foolish can you get.”  Admin

For decades, human design engineers have been laboring to make more efficient machines, like propeller blades that produce steady airflow patterns. Our thinking has been fixed on the idea that smooth surfaces are the best basic form, but studies on whales and dolphins are changing that.

A whale flipper has a bumpy edge. After incorporating some bumpy, irregular features into experimental fan blades, Dr. Frank Fish of West Chester University observed, “This design has been shown to be more efficient and also quieter, but defies traditional engineering theories.”1 It turns out that the bumps on whale flippers have a purpose—to reduce drag, increase lift, increase fluid flow efficiency, and decrease the risk of stalling.

Scientists have increasingly looked to nature for structural design elements, a practice known as biomimicry.
