Woah woah the text says "human referring to the true men, dicronius". That's kinda awesome. Kinda gives me X-Men vibes where you can look at the mutants (or in this case the dicronius) as the "new" evolution, rendering normal humans basically just chimps.
Not sure if this means the dicronius were around before humanity or are just a newly evolved species. Also, Lucy talks like she is some dicronius elder, which is kinda important.
I love when stories can reveal so much backstory in a random aside line like this.
