Learn how to read, dreamer. The article is talking about Stalin’s formative period, at which time he was a FULL-ON Darwiniac. True, he later abandoned Darwinism in favor of Lysenko. But then again, he did so at a time when the entire world of Evos were abandoning Darwood in favor of other godless evolutionary theories (indeed, it got so bad for Derwood that Huxley referred to that time period as the “Eclipse of Darwin”).
When Stalin ruled the USSR, and for decades after, learning or teaching the theory of evolution through natural selection would get you arrested, sent to Siberia or shot.
The Communists recognized that Darwin's theory was antithetical to their political philosophy.
Lysenko and his Lamarkism was not ascendent anywhere but the USSR, and there it was purely for political/ philosophical reasons, not because of any scientific findings.
