A seed must be:
- light

Evolution overs over time such that the best traits are being passed on from successive generations in every species or populations. We can compare these different species from a common ancestor. Evidences include fossil evidence, genetic evidence, comparative anatomy and more. These are usually shown in phylogenetic trees. Most apparent differences between wolves and dogs are their anatomy or morphology. Fossils support these. Behavior between them are different especially in terms of mental differences.
Best answer is A.
