It would have been here earlier but the "sequencing and assembling the platypus genome proved far more daunting than sequencing any other mammalian genome to date".

The sex-determinging genes alone are the most complex found so far in a mammal (or most other animals for that matter):

XXXXXXXXXX makes a female platypus, XYXYXYXYXY makes a male (with no less than ten chromosomes involved).
