===humanoid (noun)===
Anthropologists and students of human evolution use the ''noun'' '''humanoid''' to refer to '''hominins''' or '''hominids''' rarely if ever.

Giving its definition for the ''noun'' '''humanoid''' Lexico wrote:<blockquote>'''(especially in science fiction) a being resembling a human in its shape.'''</blockquote> 
<blockquote>''‘a three-eyed humanoid’<br>‘We feel death in these shows in ways we don't in the rubbery cartoon world of humanoids that comprises the Hollywood epic and action film.’''</blockquote>

Lexico also gave examples of non-scientific usage of the noun '''humanoid''' to refer to pre-humans; but the word is confusing, and betrays a lack of knowledge about theories of human origins &mdash; it is best left in the realm of science fiction.
