 to Homo sapiens sapiens, while at the same time there was gene flow between the various populations. According to the Weidenreich Theory, genes that were generally adaptive (such as those for intelligence and communication) would flow relatively rapidly from one part of the world to the other, while those that were locally adaptive, would not. This is contrary to popular theories of human evolution that have one superior race displacing other races. A vocal proponent of the Weidenreich theory was Carleton Coon

Professor Weidenreich also renamed Gigantopithecus blacki to Giganthropus blacki, based on a theory that primitive forms of man were much larger than the more recent ones. However, as this theory is contradictory to the Cope-Deperet rule (which states that in straight evolution lines of non-flying animals the size of species increases, not the other way round), it was rejected by Professor Dr. von Koenigswald
