Answer:
They have similar base sequences.
Explanation:
The relationship between two species might be so close that the evolution of one species affects the evoluution of the other species.
Scientists compare the DNA base sequences of different species to determine evolutionary relationships. Species that share more similarities in their DNA bas sequences are more closely related than those who share fewere similarities.Scientists hypothesize that if two species have similarities in their base sequence,they share a common ancestor.
<span>This is the acquisition stage. During this stage, the learned behavior is being taught and the learner begins to link the stimulus with the response.
