Single cell organisms after all!
So that shared one brain cell meme is true?!
Ultimately, they found something surprising: a tiny deletion on the X chromosome that causes a gene named Arhgap36 to turn on in pigment cells.
This is no ordinary gene. In humans, Arhgap36 is linked to certain neuroendocrine tumors and plays a role in cell signaling during development. But it had never been associated with coat color in any species.
In orange cats, its unexpected activation in pigment cells throws a wrench into the cellular machinery responsible for melanin production. It blocks a late step in the pigment pathway — effectively flipping the fur’s palette from dark to bright orange.
Maybe its the same reason why giraffe necks are so long. — its those pesky mutations causing havoc in the animal kingdom again.
Even tigers 🐅??
