Why It Might Be Time to Rethink the Human Family Tree
Summary
The article argues that the traditional three-genus taxonomy of human relatives (Homo, Australopithecus, Paranthropus) does not reflect true evolutionary relationships, due to mosaic evolution and new fossil/genetic data. It proposes consolidating into a larger Homo genus to reflect real lineages and interbreeding, discusses the implications for language and everyday speech about humans, and notes the costs of changing taxonomy.
