Post by: Anyy on Mar 31, 2018 b Changes in amino acid sequence due to mutation, that dont disrupt the functioning of a protein accumulate gradually over time. The further back in time that the ancestors of two species split from one another, the greater the accumulation of these changes in their separate lineages. Species that share a more common ancestor have more similar amino acid sequences because fewer changes have occurred. |
