Earthworms, which are land invertebrates, and caecilians, which are amphibians, have evolved with traits that enable them to burrow; 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

Option A , Convergent Evolution

Explanation:

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.  

Hence,  option A is correct.

answer: 2

explanation:

yes
