Dear 100 Hour Board,
How would the world be different if humans were cold-blooded?
Office buildings wouldn't be so dang cold during the summer.
For the most part humans would probably only live where cold blooded animals currently live. I wasn't able to find any maps of cold blooded animal habitats, but I think it's safe to say that Wisconsin would be uninhabitable for most of the year.
Someone asked this on Quora and got some really dope answers. Kevin McLauchlan's answer there is exactly my cup of tea. mmm tea. I want some right now. Favorite ideas from Kevin:
- we couldn't keep our erect posture. There's just not enough surface area exposed to the sun.
- we would be lazy lazy lazy. We would mostly wait for food to come to us. We wouldn't travel much, have settled cold places, or do really anything at night or in the winter. Think less motion in every way. Smaller range, smaller world.
- less hormone driven behavior.
That last idea is interesting to me because the blood flow obviously facilitates hormone delivery. But I never made the connection to hormone activity and mobility. Its interesting to me to think of hormones as necessary to motivate movement across the landscape. Cool stuff.
