Traits such as skin color and height are variable throughout the human population because these traits are controlled by more than one cell. The cells don't perform at the same rate and don't produce the same biomolecules. Therefore, the maximum height of a person is not achieved which results to variations.
Continents can be made to fit together like a piece of jigsaw puzzle, also the similarity of the Atlantic coastlines of Africa and south America was also recognized so Alfred wegener in the early 1900s made a strong case for continental drift , he noted that south America, Africa,India , Antarctica, and Australia had almost identical Paleozoic rock and fossils. He then reassembled the continent to form a giant super continent which he called pangea , his reason was that the similar rocks and fossils were easier explained if the continent are joined together.
Explanation:The fossil record helped to support the idea of pangea becos these fossils were found in all 5 continent as at that time so it could only be possible if these continent were actually joined together for example the fossil remains of land-dwelling reptiles Lystrosaurus and Cynognathus are found in Triassic-age rocks on all the five continent, also the plant Glossopteris is found in Pennsylvania and Permian-age rock on all five continent
