Question

Species A GCTGCCCAT
Species B ATTGCCCGT
Species C ACTGACCGT

The table above shows the differences in a DNA sequence between three species. Which of the following best summarizes what can be inferred from comparing those differences?

1. You can infer that A and C shared a more recent common ancestor than A and B or B and C
2. You can infer that B and C shared a more recent common ancestor than A and B or A and C
3. You can infer that A and B shared a more recent common ancestor than A and C or B and C
4. You can infer that A and B have been evolving independently longer than C has

Answer 1

2 because the sequences have less differences then the other combinations
