Finding that two species have similar DNA is an example of studying which characteristic to determine evolutionary relationships?

A. chromosome similarity

B. biochemistry

C. structural similarities

D. geographical distribution

Structural similarity

Explanation:

This is because DNA transcribes to form rRNA, which is later translated to form proteins that play key role in carrying out functions based on the structures they are present in.

phylogenetic tree is the tree of life or evolution tree. it shows the different branches of evolution. the sequence goes like tissues - coelom - backbone - endoskeleton - segmentation

the answer would be d : p
