understand: evidence of common ancestry
google classroom microsoft teams
which of the following methods would be best for determining the evolutionary relationships among a group of species?
choose 1 answer:
a comparing the amino acid sequences and fossil lineages of the species
b comparing only the anatomical features of the species
c examining the embryological anatomy of each species individually without comparing the species

Explanation:

To determine evolutionary relationships, a comprehensive approach is better. Option A compares amino acid sequences (molecular evidence) and fossil lineages (paleontological evidence), which together provide strong evidence for common ancestry. Option B (only anatomical features) is limited as some anatomical similarities can be due to convergent evolution. Option C (examining embryology individually without comparison) doesn't help in determining relationships between species. So A is the best method.

Answer:

A. comparing the amino acid sequences and fossil lineages of the species
