That posting is wrong.
Smalltalk's roots are very firmly planted in Lisp,
with perhaps a touch of Logo (which also had its roots in Lisp).
The classic Smalltalk-76 paper even contains a meta-circular
interpreter, which I found reminiscent of the old Lisp one.
The "biological" metaphor in Smalltalk is actually a SOCIAL
metaphor: sending and receiving messages, and a "social"
model of agents with memory exchanging messages naturally
leads to anthropomorphisms.
The other classic OO language, which inspired C++, which
inspired Java, which inspired C#, is Simula 67, which has
its roots in Algol 60. While Simula 67 was sometimes used
for simulating biological processes, the main background
was discrete event systems like factories and shops; there
are no biological metaphors in Simula.
