All life's plenitude is worthy of life

The scientists of era of Modernity (1870s-1960s) believed that Darwin's evolution would be best served by Man giving Natural Selection a leg up - by Mankind draining the gene pool for humans and non-humans alike.

Cue Auschwitz and Aktion T4 and cue today's ever more rapid extinction of all species other than our own.

Those scientists were dead wrong - it was just bad science.

Nazi Aktion T4 as 'death by meritocracy'

The Great Chain of Being, as educated Man saw it anyway, was God's ordering of classes of being --- from very imperfect to PERFECT.

Nothingness was at the very bottom, and God at the very top : Man was in the high middle area.

But note the perfect and imperfect were born that way : their perfectness was ascribed ,  not something learned and earned/un-earned by being marked in some merit testing.

Great Chain of Being vs Darwin

In the pre-1859 thinking that lay behind the concept of The Great Chain of Being , all species of Life were born on the same day (all had a common birthday) but all were subject to different individual creations (so had different 'parents' , in a metaphorical sense).

 In 1859, Darwin neatly reversed this : now all species of Life had one common parent (some slimy little bacteria) but all the species had wildly different birthdays, as Life branched out over time from that early single bacteria's beginnings.

Cue the scientific 'justification' for Aktion T4 and the Holocaust.

'White Finches evolved to be Black' : is ANY of this true ?

Well 'finches' are 'finches' - we'll let that semi-accurate layperson definition stand, for the sake of argument.

But did all the white finches, as gradually as Darwin claimed they must, all turn into black finches ?

But might it really be that most finches used to white and now - currently and only here and not there - most are black ?
