Humans on the tree of life

Image caption:
This tree is based on morphological and genetic data. Chimpanzees and humans form a clade with genes sequences that differ by only 1%. This genetic similarity made it hard to figure out exactly how these two primates are related, but recent genetic studies have strongly suggested that chimpanzees and humans are each other's closest living relative.
