We are all a bit more alike than we may think:

“variations [such as for eye colour, height, etc] constitute an extremely minor portion of the genome.

They are magnified in our imagination because of cultural, and possibly biological, tendencies that tend to amplify differences.

…the two most extreme human variants – male and female – share 99.688 percent of their genes”
