And their genetics are even weirder with elements of bird, reptile and mammal genomes. What’s more, instead of having XY (mammals) or WZ (birds) sex-determining chromosomes they have a bunch of proto-W and proto-Z elements which taken together determine whether it’s a boy platypus or a girl platypus. I’m left with two possible conclusions
- They really are on a cusp between reptiles, birds and mammals
- God sub-contracted Australia. The requirements included a duck, but the design team had only seen the White Paper and did the best they could with what they could scavenge for the spare parts bin. They released Duck, Australian v.0.3 just before the deadline and promised to have v1.0 done by the next release. But what with the Fall and the Flood that project was cancelled
