To the untrained eye, certain butterflies can look essentially identical to corresponding varieties of another species. This way they can evade predators, who won't eat them because the insects they're copying taste terrible.

How does a single-cell egg turn into a swimming, metabolizing, hunting tadpole? Common understanding holds that frog DNA carries the required instructional building plans. However, developmental biologists serendipitously discovered that tiny facial features were outlined with bioelectricity just prior to their formation inside frog eggs.

In his book Why Evolution Is True, evolutionist Jerry Coyne of the University of Chicago made the following jaw-dropping statement:

Scuba divers can explore underwater depths firsthand because of specialized equipment that was developed in just the last century. Likewise, solar-powered airplanes currently in development promise to provide fuel-free flying. These inventions open new realms for human exploration, but the arachnid and insect equivalents of their equipment have been on the planet for ages.

Fruit flies, the subject of over a century of intense investigation, have not ceased yielding secrets. In a study published in 1980, core fruit fly genes were altered, one by one, and the resulting plethora of dead flies proved that there was no "wiggle room" to add the mutations that evolution would require.¹ Now, researchers have found another way to break the fly.
