One of the Anti-Evolutionist's favorite crapola arguments is usually along the lines of, "you can't show me one example of one species evolving into another" or some such.

This might be one:

Amphibians are ectothermic, tetrapod vertebrates of the class Amphibia (Greek ἀμφí, amphi, "both" + βíος, bios, "life"). They inhabit a wide variety of habitats with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Amphibians typically start out as larva living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely upon skin.

It's most widely accepted that life started in the ocean, and some of the critters evolved ways of getting out of the water and up onto the land.  Seems to me an amphibian just might be the example that way too many god-botherin' dingle-butt derps keep telling us can't possibly exist.
