Earthworms, which are land invertebrates, and caecilians, which are amphibians, have evolved with traits that enable them to bur
row; both live in moist soil and have an elongated and slender body. Which evolutionary mechanism do they represent? A- convergent evolution B- adaptive radiation C- reproductive isolation
In a convergent evolution, similar characteristics or traits develop in species belonging to different race or ancestry groups.
As in this case , Earthworms are invertebrates while caecilians are amphibians but they both have the ability to burrow, have slender long body and also live in similar habitat (i.e moist soil) . Both the species (i.e earthworm and caecilians) have different origination but they have adopted similar characteristics/traits.
<span>I would say "Convergent evolution." Two types of organisms have converged (after perhaps separating) into a common way of life, from varying circumstances</span>
