Step 1
The similarity between the two organisms is most likely a result of
Answer
The correct answer is D. convergent evolution.
Explanation:
Convergent evolution occurs when different species independently evolve similar traits as a result of adapting to similar environments or ecological niches.
In this case, the Tasmanian tiger and the American grey wolf demonstrate similar hunting behaviors and physical structures, despite evolving in different geographical areas and from distinct ancestral lines. This similarity serves as an example of how different organisms can end up developing analogous characteristics due to similar environmental pressures.
