Worm-like amphibians referred to as caecilians might have misplaced their legs because of the identical genetic tweaks that snakes have.
An evaluation of the amphibians’ genomes means that caecilians and snakes – separated by a whole lot of tens of millions of years of evolution – converged on the identical mutations when ditching their limbs. The findings present insights into the genetic underpinnings of the evolution of limblessness.
The 200-some species of caecilian are completely limbless, and dwell secretive lives in tropical soils or waterways. They have small or nonexistent eyes and …
