The genetic blueprint of the Platypus (Ornithorhynchus anatinus) has been deciphered by an international team that includes Australian scientists, and published in the journal Nature.

Nature: Genome analysis of the platypus reveals unique signatures of evolution
The Abstract states:
We present a draft genome sequence of the platypus, Ornithorhynchus anatinus. This monotreme exhibits a fascinating combination of reptilian and mammalian characters. For example, platypuses have a coat of fur adapted to an aquatic lifestyle; platypus females lactate, yet lay eggs; and males are equipped with venom similar to that of reptiles. Analysis of the first monotreme genome aligned these features with genetic innovations. We find that reptile and platypus venom proteins have been co-opted independently from the same gene families; milk protein genes are conserved despite platypuses laying eggs; and immune gene family expansions are directly related to platypus biology. Expansions of protein, non-protein-coding RNA and microRNA families, as well as repeat elements, are identified. Sequencing of this genome now provides a valuable resource for deep mammalian comparative analyses, as well as for monotreme biology and conservation.

Platypus is clearly the genetic ancestor of Gore’s “manbearpig”.
Hmmm, seems further study is warranted. Kids in school, teeth need fixing, wife needs some elective surgery what’s a researcher to do?
