Answer:
Are organisms able to evolve?
Explanation:
At the time, species were considered to be fixed. Change in species, especially change from one species into another was not considered possible. However, his observations made Darwin question this, because he observed species that were unique in isolated islands, that were related to other, common species present on the continent. His conclusion was that isolation had brought species from the continent to change into new species when they had to adapt to the new conditions on the islands.
