Hm no, the problem is much more at the roots of science than you think. Most of biology is based on humans' biased assumptions and expectations. For example, only when queer theory was developed did biologists really grasp how much deviant the animal kingdom in regards to sex, gender and sexuality actually is.

Just think how many layers deep this is: humans exist -> develop social structures -> develop social constructs that feel essential -> try to describe their own biology through the lense of all the prior layers -> develop awareness about some social constructs -> revisit their own biology but still with a lot of biases

What you express by saying that it isn't possible anymore to just speak about biology is imo rather an expression of denying certain advancements we've made. Our ideas and models of biology a few decades ago may have been simpler, but not more true. We've just realized to some extend how complex biology is and how our prior models have made many poor assumptions.

EO Wilson is having his own concepts and biases of human societies and projects them onto this pseudoscientific narrative. He is obviously not aware of his own position in society and how it shapes his assumptions.
