That work led to the emergence of the recombinant DNA technology thereby providing a major tool for analyzing mammalian gene structure and function and formed the basis for me receiving the 1980 Nobel Prize in Chemistry.

Thousands of years ago humans domesticated every possible large wild mammal species fulfilling all those criteria and worth domesticating with the result that there have been no valuable additions of domestic animals in recent times despite the efforts of modern science.

I've become sort of an accidental advocate for attachment parenting which is a style of parenting that... basically the way mammals parent and the way people have parented for pretty much all of human history except the last 200 years or so.
