The paragraph Barker has written about Honey Bees on the same website is possibly even more wrong:
"Honey Bees are an interesting case. They have three classes: a female queen, female workers and male drones. Their sexes cannot be compared or categorised in the same way that they are for mammals, however. The 'male' bees develop from unfertilised eggs and are, in effect, females. They possess only one set of chromosomes, contradicting what may be perceived as the 'normal’ male and female gender-binary. With some bees never reaching full development, It could even be considered that there is actually only one sex of honey bee.
Examples like the Honey Bee are important. It is simple to define humans as having male or female sex and a corresponding gender, classifying anyone who bends or deviates from pre-defined gender norms as odd and freakish. But, as we've seen, sex and gender variation are found throughout the natural world. Maybe it is time to think outside the box! "
So, Barker says The 'male' bees develop from unfertilised eggs and are, in effect, females. This is total BS. The male drones are, well, male. They can mate with the queen and produce sperm. They are fertile adult males. So not any kind of female at all.
Barker then says With some bees never reaching full development, It could even be considered that there is actually only one sex of honey bee. Again, total BS. Bees all reach their full development, they are either a queen, a worker or a drone. Female workers don't get to reproduce, but they are adult bees.
The last paragraph is just... words fail.
Why was a chemist/physicist asked to write factual information about a biological sciences display??
