just thinking about how cats are born with very weak internal heat generation (it's done by the liver) and how humans are different, we have big livers because we have almost no hair, most of the hair is only in the less fleshy more bony parts of our body, where insulation is needed.

i wonder if this is because we were from bipedal apes who grew big brains for catching animals and figured out how to skin them and wear their fur, and this also implies that we must have had a need to increase our insulation meaning that the pressure of glaciation periods probably drove us to do this.

first we lived in the equatorial regions, and then we became dominant there, and lost most of our hair and instead sweat a lot to stay cool, and then we spread north and south and needed cold protection and started wearing skins.

i love wearing leather, especially soft leathers like rabbit and goat and shoes... they look so cool also.

another example of how retarded veganism is too, you literally can't make more thermally insulating materials than animal hair.
