- Multiple ChoicePlease save your changes before editing any questions.When scientists compare animals currently living on different continents, they often find those with similar characteristics, who are not actually close relatives, living in similar environmental conditions even though they are geographically very distant. One example is the Anteater/Armadillos of the Americas and the Pangolin of Africa. What can we deduce from this evidence?Living things can adapt similarly to similar environments over time.Living things do not change over timeThey must all have the same recent common ancestorI don’t know
