Which one is correct?
Should human be plural or singular. Plural should be correct, right? because there are many . and if so, animal should be plural as well?

Humans are animal too
Humans are animals too
The human is animal too

[Shakespeare's brother]

Human is a singular noun. It is also an adjective. Animal has the same status. Therefore, to talk about more than one human or animal you must add an 's'.

[Mohammed Abu Risha]

Humans are animals too.

Or, you can say:

A human is an animal too.

The zero article before Humans and the indefinite article (a) before "human" bith serve the generic meaning of the word. I mean by generic that when you say "humans" you are referring to all human beings in general. This generic function is also achieved by saying "a human".
