Since Charles Darwin's time, this phylogenetic tree of human evolution has been used in evolutionary biology. As a result, one would think that most scientists would be very comfortable with "tree thinking", reading and interpreting phylogenies by now. However, the tree model of evolution turns out to be somewhat counterintuitive and easily misunderstood. This could explain why biologists have only recently developed a rigorous understanding of phylogenetic trees. This understanding enables modern researchers to use phylogenies to visualize evolution, organize biodiversity knowledge, and structure and guide ongoing evolutionary research, as illustrated in this phylogenetic tree of human evolution diagram.
