She says "there is no language in nature" which does not seem accurate. Even though she might mean something else or a particular form of language but even then, bees and birds still use sound and something similar to language.

Is it just me?

for e.g. the form of communication used by bees is very well known now, it involves not just spatial movements but also "buzzing" which is totally similar tot he sounds we make, they just lack vocal cords.
