Funny thing I noticed today:
When my biology textbook needs a photo of a person doing something for an example, they include people of various genders and races.
But when they need a drawn diagram with a generic symbol for human-ness, they use a white male.
(This is not entirely fair. I was flipping through the book just now, I found the later chapters about human organ systems featured diagram-people of all colors and even a few ladies. However, these chapters aren't covered in my class, and for all the chapters on genetics and evolution our diagram-people were exclusively white men. I am now kind of curious as to why the diversity of life they keep talking about doesn't show up until Unit Six. However, I am pleased to know I will be less annoyed by the diagrams in Human Biology next semester.)
