How did humans start speaking? One idea is that humans already had a language of thought (LOT). Perhaps this was perfectly developed in our heads (like a snowflake) before we really tried to communicate using language.

The Language of Thought Hypothesis is that thinking takes place in a mental language. This mental language is probably basically the same for everyone; it suddenly appeared in perfect form in the brains of early humans. What do you think of that?

Do you think this is true? All humans have this perfectly formed LOT  in their heads, and this LOT is basically the same for everyone. If it is true, how and why did human beings develop this thinking ability before other animals and before they could speak themselves?

At some point, one human ancestor suddenly developed the ability to think in a language. She couldn’t speak yet, but she had a perfectly developed language of thought in her brain. What do you think of that? Can you think of any other possibilities?
