There is now a Graphic Book (which is apparently some kind of cartoony thing kids these days read) which is a biography of Darwin. I’ve not read it but I have a free chapter for you, here. That’s courtesy of the NCSE.
Here’s the Amazon Link and from that site, a description:
Darwin: A Graphic Biography is an inspiring expedition into the physical and intellectual adventures of Charles Darwin. Presenting Darwin’s life in a smart and entertaining graphic novel, Darwin: A Graphic Biography attempts to not only educate the reader about Darwin but also the scientific world of the 1800s. The graphic medium is ideal for recreating a very specific time frame, succeeding in placing the reader right next to a young Darwin on a “beetling” expedition. With specimens in both hands, and anxious to get another, Darwin ends up stuffing the third beetle into his mouth. Darwin’s life presented in this form is an inspirational tale for kids of all ages. They’ll be sure to identify with a curious young Darwin finding his way on youthful adventures in the fields near his house. The ups, downs, and near-misses of Darwin’s youth are portrayed honestly and without foreshadowing of his later fame. This is a key point for younger readers: that Darwin wasn’t somehow predestined to greatness. He was curious, patient, and meticulous. He persevered–a great lesson about what science is all about.
