Over the river and through the woods to Aunt Elaine's house we went. And along the way we passed these sweet emus, who probably aren't all that sweet.

And I learned, from Erin who is sweet, about ostriches and emus. And that led me to learn about the word "Gondwana." I knew about the landmass but not the name. Gondwana. It rolls nicely off the tongue.
From USAToday online:
"... ostriches and emus ... apparently share a common ancestor who lived long ago on the gigantic landmass, Gondwana. When Gondwana broke up about 75 to 85 million years ago, Africa split off, and then Australia/Antarctica sailed slowly away.... With a widening ocean between them, the ostriches and emus were forced to evolve separately thereafter. At least, this is the best current theory."
