Long Tailed Macaque

This question refers to a series of experiments where scientists in China injected some monkey stem cells into pig embryos and implanted these embryos into sows.  They implanted over 4,000 embryos. Eventually 10 piglets were born. Two piglets had monkey cells in some organs and tissues.  The experiments were reported in New Scientist 6 December 2019, and Protein & Cell, 28 November 2019, doi: 10.1007/s13238-019-00676-8.

But note well: these piglets were not hybrids.  No pig and monkey genes were combined.  The two piglets had separately recognisable monkey cells growing in their bodies.  They were chimeras, not hybrids. The term ‘chimera’ comes from Greek mythology and describes a creature composed of parts from different animals.  All the monkey cells were fully monkey cells with a monkey genome, while all pig cells in the piglets’ bodies possessed a complete pig genome. 

It is possible for monkey cells to grow in a pig embryo because many mammals (pigs and monkeys included) have similar growth factors that stimulate cells to grow and differentiate. Yet analysis showed that only a small proportion of the piglets’ cells were monkey cells – between one in 1,000 and one in 10,000. 

All piglets died soon after birth, so in the end the experiment was a failure. The pig kind cannot interbreed with the monkey, which is what you would predict given God created them separately and unrelated.  

It is also of interest to note that these experiments were done in atheistic China, which regards man as just another animal and accepts no obligation to any Creator who gave man or animals any rights to care. It is unlikely that any of these experiments would have been allowed in the west due to ethics committees still having a residual Christian base of accountability and animal welfare. Sadly, we predict that such opposition will disappear in the west whenever atheistic evolutionists dominate.
