I am fascinated by this observation and I think you are correct. Cultural
evolution is Lamarckian. So is the evolution of language. When I was
learning the english language as a toddler, the word 'internet' was nowhere
to be found. I have successfully passed this acquired trait on to my
children. Another view of language is what I heard an anthropologist once
say. Language is like a parasitic virus that has infected our brains and
evolves along its own path. And indeed random mutations to the
pronounciation can separate two dialects into two languages in about 1000
years.
