{UAH} Darwin was right: Airplanes evolved the same way birds did

The biggest sticking point for people who don't believe in evolution is the idea that because it happens over such an immense timeline, it can't really be tracked. It can, of course, through the fossil record and gene sequencing, but some people don't want to hear that noise. Well, scientists from the American Institute of Physics have a more acute example, one that's only been around for a century or so: Airplanes. Just like their living counterparts, they've evolved to be more efficient over time, adapting to the same principles of physics.
