Aurochs!

One of the things I learnt about in studying mediaeval history about the aurochs, giant wild cattle in Europe that are now extinct. The last died out in the 17th century. They were over 6 feet tall at the shoulder. Remember the cave paintings of cattle? Those were aurochs. Apparently their DNA has been sequenced, giving scientists better insight into the species. Nifty, hmmm???

Speaking of DNA sequencing, I forgot to mention when it came out the story of the man from the now-extinct Saqqaq culture of Greenland from about 4000 years ago whose DNA has been studied to try to understand his roots.

After 4,000 years, DNA suggests ancient Greenland man had risk of baldness and even dry earwax

Dry earwax, incidentally, is a trait more often found in Asia. It is believed that the Saqqaq actually migrated from Siberia. There is an artist's concept of the man in the article.

Anyway, DNA archaeology is on the cutting edge of science. And who knows, maybe someday we'll have aurochs again.
