  34. Animal Communication • Many species communicate • From insects to apes • The communicative abilities of all species can only be understood as part of their behavioral adaptation to their niches • Thus no two species communicate in the same way • You may have seen a dog trying to sniff a cat´s rear end • And our language is unique to us.
