Except it’s part Darwinism and part Lamarkism

from Baba Brinkman – Artificial Selection on Rap Genius

Meaning

Jean-Baptiste Lamarck proposed an alternative theory of evolution [developed independently from Darwin’s] according to which traits acquired throughout your life are passed on to your offspring [e.g giraffes are tall because they kept stretching their necks generation through generation]. in the case of Baba, his grabbing his crotch is a behavior he acquired in life; it’s not genetic.
But he probably doesn’t want it to be passed on to his offspring, I hope.
