Knowledge: Big animals know what they can eat or not by smell and other animals like small and medium size know when to hide by instinct. On the other hand, dogs can cross-breed to create new breeds like goldendoodles made from poodles and golden retrievers.

Conversation:
I love alpacas.
How nice, did you know that alpacas are a domesticated camelid?
I did not know that, I thought they were llamas.
Yeah, they are similar but alpacas are not llamas, people often confuse alpacas with them.
Now I understand, are they related?
Yes they are, both animals are related and can even cross-breed.
Oh wow, I did not know they could even do that. What other animals can cross-breed?

Response: Yeah, dogs can also do that. Like goldendoodles are made from poodles and golden retrievers.
