Genome analysis of the platypus reveals unique signatures of evolution

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.(abstract)

Outside a dog, a book is man's best friend.

Inside a dog, it's too hard to read.

I have always thought that the platypus was God’s way of showing his sense of humor.

Upon sequencing the platypus’ DNA, geneticists were astounded to find within its genetic code the phrase “LOL! J/K LOVE, GOD”.

"The divergence occurred some 166 million years ago from primitive ancestors combining features of both mammals and reptiles."

So..., the duckbill, webfeet, egg-laying, and venom-spouting all arose quickly and together at 166MYA?

But is it Kosher to eat?

No.

$10bucks says it DON'T taste like chicken...

"$10bucks says it DON'T taste like chicken..."

If'n it did, it'd be called a Chickenbill Platypus, wouldn't it?

[Unknowing]

It’s half bird or dinosaur, so it would be worth ten bucks to find out. Maybe a cross between a chicken (or duck) and a squirrel?

[Chode]

prolly tastes fishy AND gamey...

I thought that was what explained nipples on men.

It sounds something like a McNamara ‘do everything’ requirement for the TFX.

This whole tread is outragiously funny … so funny, I’m having trouble typing. LOAO! Tears down my face over the humor here. I just have sympathy for the poor Platypus, the joking and laughing notwithstanding.

[doc1019]

Yes, yes, yes … another example of God’s sense of humor. LOL!
