El enigma de Darwin

The integration of Darwin's theories and modern medicine felt seamless and compelling. I'm curious whether this was inspired by personal interest or research during writing.

The story really took off once the mystery deepened, but I wonder if the beginning was intentionally more relaxed to set the scene or if it could have been tighter.

It added a layer of historical intrigue that made the mystery feel even more profound. I wonder if the idea was sparked by a real historical puzzle or purely fictional.
