I think it’s really much controversy , little substance when it comes to ( non human ) animals
I raised and selectively bred pigeons for several years , there is occasionally a squirrelly bird that needs to be culled from time to time , but that is to be expected .
Phil mentioned Jacob ( Genesis 30-31) selective breeding according to trait , and his methods are still sound today ( max boer goats uses the same methods ) , according to Jacob , God clearly supports it .
As to bringing back the wooly mammoth , I don’t see it effectively repopulating it in any significant application , and it isn’t likely to make a huge comeback , more a scientific novelty …meh …
As to plants , we continue to manipulate genes , some for the better , some for worse …really , in my opinion , splicing is the real threat with plants .
Viral and bacterial applications seems to get sketchy in the wrong hands , but I feel this is due to a lack of moral or ethical foreknowledge.
With humans , it’s hard to say from a detached standpoint , do we attempt to replace natural selection ? we have already greatly reduced its effect on our species through medicine .
Morally i find it distasteful . Who decides what is best for our species ? Do we have the right to attempt to remove genetics we find unsavory ?
Who decides where the limits are ? Sure , removing the genetic predisposition toward addiction sounds great , but then , does it serve a purpose ?a sort of ingrained warning against drunkenness ? What happens when someone with flexible ethics decides a particular race should be eliminated ? A particular mutation ?
Where is the line ? At what point does it damage our uniqueness ? Our Einsteins and Teslas ?
Just my initial thoughts on the topic
