My mom says that "negative" blood-types aren't natural (she means that we evolved to have them) but she doesn't know where or why they came about. Do you guys like you could answer that for her? Thanks!

You forgot to tell people about the Bombay blood group, o blood group actually contains 'H' antibody , but theres a blood group that doesn't have the H either. It's the bombay blood group (Hh), and no I'm not talking about. 'O-'

What about HH-. Didn't knew even so trusted channel can make such blunders. I mean i know it's a rare blood type but it still deserves a honorable mention.
Thomas Thetankengine (6 months ago)
I don't know what the people with O- are complaining about. My cousin has the Bombay blood group which only about 30,000 people in the entire WORLD have. And the Bombay blood group can only take from the Bombay blood group. Y'all lucked out

This video the most interesting mix of comments of any video I have ever seen. Most of the commants are either about commenters' blood types or commenters' families' blood types. Some are about how good the video is. Two comments are facts about blood types. There is even one wierdly political comment.

As someone who has worked as a lab tech at a blood bank for 10 years, I can honestly say this video does a great job of giving a basic overview of blood types. It is complicated stuff, and I haven't seen many videos that do a good job at explaining it.
