Humans exhibit the most linear relationship with birds. This is due to several similarities in embryonic development, respiratory systems (lungs), and the presence of feathers compared to hair and skin. While reptiles and amphibians share certain characteristics, birds share a more recent common ancestor with mammals compared to those other groups, making the relationship more linear.
