“Cloning is great. If God made the original, then making copies should be fine.”*…

 

Alternately:

Every new step in the direction of simplification – toward monoculture, say, ore genetically identical plants – leads to unimaginable new complexities…”
― Michael Pollan

In any case,

Animal cloning has been around for nearly 20 years, but has mostly been done for the sake of research. Now, a new commercial venture in Tianjin, China, plans to clone 100,000 beef cattle a year for meat production beginning in the first half of 2016.

The enterprise, made up of several academic and commercial organizations with financial support from the Chinese government, has the ultimate goal of ramping up production to a million cow embryos a year…

As we ruminate on reproduction, we might send biological birthday greetings to Erasmus Darwin; he was born on this date in 1731.  Erasmus was an accomplished doctor (he declined an offer to be personal physician to Charles III), but is better remembered as a key thinker in the “Midlands Enlightenment”– a founder of the Lunar Society of Birmingham and author of (among other works) Zoonomia, or, The Laws of Organic Life, which contained one of the first formal theories of evolution… one that foreshadowed the theories of Erasmus’ reader– and grandson– Charles… all of which may soon seem quaint.

As we celebrate the beauty in the ephemeral, we might recall that it was on this date in 1997 that Ian Wilmut, Keith Campbell, and their colleagues at the Roslin Institute (part of the University of Edinburgh, Scotland) announced that they had successfully cloned a sheep, Dolly, who had been born on July 5, 1996. Dolly lived her entire life at the Institute, where (bred with a Welsh mountain ram) she gave birth to six lambs. She died in February, 2003.

Silicon-based (and other alternate) forms of life are a staple of speculative fiction.  But are they as far-fetched as they might seem?  In Smithsonian‘s Daily Planet blog, astrobiologist Dirk Schulze-Makuch suggests not

It would be extremely “earth-centric” to presume that the biochemistry on our planet is the only way life can operate. But just how different can it be? One extreme example are the “Horta,” the silicon-based life portrayed in Star Trek. Could we expect organisms like that on a terrestrial, meaning Earth-type, planet? Most likely not, because the biochemistry of life is intrinsically related to its environment. On Earth, silicon and oxygen are the main building blocks of Earth’s crust and mantle. Most rocks, particularly volcanic and igneous rocks, are built from silicate minerals, which are based on a silicon and oxygen framework. Any free silicon would be bound in these rocks, which are inert at moderate temperatures. Only at very high temperatures does the framework become more plastic and reactive, which led Gerald Feinberg and Robert Shapiro to suggest the possible existence of lavobes and magmobes that could live in molten silicate rocks

One can read the full story at “Is Silicon-Based Life Possible?

And one can muse on a resonant issue: if we earth-bound humans tend to be pretty precious about our definition of life, we are even more sensitive– indeed, often down-right chauvinistic– in our understandings of consciousnesssentience and who/what can or can’t enjoy them.

As we study up for the Turing Test, we might send animated birthday greetings to Hans Adolf Eduard Driesch; he was born on this date in 1867.  The father of experimental embryology and the first person to clone an animal, Driesch was also the creator of the philosophy of entelechy—  and thus the last the last great spokesman for vitalism.  Following in the footsteps of Epicurus, Galen, and Pasteur, Driesch argued that life cannot be explained as physical or chemical phenomena.
