Should We Clone Neanderthals?

From the recent March/April issue of Archaeology. Zach Zorich writes:

If Neanderthals ever walk the earth again, the primordial ooze from which they will rise is an emulsion of oil, water, and DNA capture beads engineered in the laboratory of 454 Life Sciences in Branford, Connecticut. Over the past 4 years those beads have been gathering tiny fragments of DNA from samples of dissolved organic materials, including pieces of Neanderthal bone. Genetic sequences have given paleoanthropologists a new line of evidence for testing ideas about the biology of our closest extinct relative.

The first studies of Neanderthal DNA focused on the genetic sequences of mitochondria, the microscopic organelles that convert food to energy within cells. In 2005, however, 454 began a collaborative project with the Max Planck Institute in Leipzig, Germany, to sequence the full genetic code of a Neanderthal woman who died in Croatia’s Vindija cave 30,000 years ago.

Eat Meat From Cloned Cattle

If you really enjoyed a steak from one cow, now you can have the exact same cow again! It’s like a Twilight Zone episode where your plate keeps refilling with the same piece of meat. In an attempt to increase production rate of quality meat, the US has been mass producing meat from cloned cattle. BBC has the report:

Some of the cattle cloned to boost food production in the US have been created from the cells of dead animals, according to a US cloning company.

Farmers say it is being done because it is only possible to tell that the animal’s meat is of exceptionally high quality by inspecting its carcass.

US scientists are using a variety of techniques to assess which animals have exceptional qualities.

These attributes include meat quality, productivity or longevity.

There is a long tradition of resurrecting dead animals for cloning – Dolly the sheep being a case in point.
