TV wildlife expert Sir David Attenborough has been blasted for ignoring gay animals.
Media studies lecturer Dr Brett Mills says homosexuality is “in pretty much every species”.
But he claims Sir David’s BBC documentaries focus on family values in animals and shun “alternative interpretations”. Sir David, 86, described male chimps hugging as “friendly affection”, while male sandpiper birds filmed circling each other were being “aggressive”.
But Dr Mills, of the University of East Anglia, insisted: “Many non-human species have complex and changeable forms of sexual activity. Heterosexuality is one of many possible options.”
