The Weird Reason Giraffes Have The Same Number of Neck Bones As You

You may have heard that humans and giraffes have the same number of neck bones. And that's true! But it isn't the whole story. See, all mammal species except for three have exactly seven cervical vert

12:46 I had to guess, I think this relates to our mamallian ancestors using the "live fast die young" strategy when we were just small shrew-things

Oh hi Deboki! Good to see a Journey to the Microcosmos host in the (semi) wild! ❤

I had a friend in highschool with 9. Just a weird random family trait. I think she said there are only a couple people in the world with it and most of them were in her family.
@
Deboki is back!!!

There may be a benefit for the giraffes to only having 7 neck vertebra in that it make give it more stability rather than having to counterbalance for more joints.
@
I wonder how many different skeletal abnormalities there are for humans that may go completely unnoticed or result in no difference in quality of life, such as a cervical rib or Adele’s extra vertebra

Oh hi Deboki. First time seeing you as host 🙋🏻♀️
@
“birds are reptiles” has changed my life so drastically
@
Okay immediate extra points for referring to birds as reptiles. It is so overdue that we start consistently doing that I love you guys keep doing it thank you thank you thank you!

I have an extra lumbar vertebra. The one that's supposed to fuse to the pelvis didn’t, and the sides of it are different from each other. One side has the proper locking joint for that region, but the other side has the kind of joint found on the upper back.
@
I like Deboki as a host!
@
debokiiiiii! thanks for all you do 😊

I get why they called it that, but it's still confusing that where you get cervical cancer is so far from your cervical vertebrae. (the cervix being the "neck" of the uterus. According to etymology online, the neck meaning is older)
@
When she said "long and complicated" at the end, I was so sure the next words would be "just like the giraffe's neck".
@
I have an extra verterbra! It makes clothes shopping hell cause even big and tall clothes are sometimes too short ;-;
@
I considered skipping this one (the title does not contain new information to me) but it was fascinating, especially the correlation between cancer and cervical ribs!

1:02 I broke my mother’s coccyx, with my head, on the way out….. I had a very bruised head.
@
I wish I could've ignored my coccyx for that whole year after I broke it and I couldn't sit normally.
@
Nice to put a face to the voice: I've heard Deboki on podcasts but never seen her on screen.
@
We have the same number of vertebrae as giraffes? That seems like a stretch.
