In a lusher, wetter Australia,
we kangaroos clung to the trees,
plucking ripe fruit from the canopies;
life was a snap and a breeze.
But dry grew the land down under,
hot wind shook us off to the ground,
deserts expanded beneath us -
hardly a meal to be found.
We just had to cover the distance.
'For Lamarck's sake give us the legs!'
Your 'just so' story concocted;
but what the Darwin! it begs.
Nah!
We roos had the legs long before that.
Just take a gander at this:
new fossil surfaced in Queensland,
so give that old theory a miss.
Been hopping and climbing for yonks, mate!
A good twenty million we span.
Your old 'just so' story is cactus;
put your dolly-zoom back in the can.
No climate change caused us a stir, bro,
no gulp and a heart fit to stop;
no grassland could frighten our arse off;
or catch us old roos on the hop.
OK, maybe fruit was the scarcer;
but we spun the earth under our kick;
no need to evolve so much further:
with a genome in bloody good nick.

Well, it's wetter today. So I'm writing from an article in 'Science' as a rainy day activity.
