We've seen it before with the skinks, that huge family of lizards that contains everything from long, dainty ankles and powerful thighs, to stumpy limbs and missing toes, to some species with no legs whatsoever.

Gymnophthalmidae means "naked eye". That's why eye doctors are called ophthalmologists and why the official uniform of every gym in the world is a birthday suit. Thankfully, they're very lax with enforcing that particular rule.
Spectacled Lizards live in a huge variety of habitats, from rainforests to halfway up the Andean mountains, and from desert-living to semi-aquatic.

Lots of them have big legs with long toes but, just like the skinks, many of them have become incredibly elongated with ridiculously long bodies and absurdly long tails. Once that happens, it seems that legs become increasingly useless. Their unending physique does all the work for them.
But species in genera like Bachia do it the other way round. Their hind limbs are more reduced than the front ones. They've found a unique way of becoming legless! It's always nice to have options. Personally I'd just keep the legs but I guess I'm just not as daring as a lizard.
