Because few things about the human eye have changed throughout the course of human evolution. The entire human race learned to become truly bipedal, yet after millions of years, we still cannot see in the dark (like actual night vision). We still only have three cones/ color receptors in our eyes, the same range of unique eyes colors (controlled by melanin), shape and disorders. The human eye never even grows during your life; it is the same size when you are born to the day you die, with the exception of some deterioration.

This also suggests that all of their taxonomic groups are similar from domain to genus. The more common taxonomic groups exhibited by the organisms, the more closely they are associated.
