Cruz is so so so so wrong about Marxism and the theory of evolution it’s not even funny. No, they don’t go hand in hand, it’s quite the opposite:

In 1948, genetics was officially declared “a bourgeois pseudoscience”;[10] all geneticists were fired from their jobs (some were also arrested), and all genetic research was discontinued. Nikita Khrushchev, who claimed to be an expert in agricultural science, also valued Lysenko as a great scientist, and the taboo on genetics continued (but all geneticists were released or rehabilitated posthumously). The ban was only waived in the mid-1960s.

Thus, Lysenkoism caused serious, long-term harm to Soviet knowledge of biology. It represented a serious failure of the early Soviet leadership to find real solutions to agricultural problems, throwing their support behind a charlatan at the expense of many human lives.
