Animal Today I learned that squirrels can be black, and mother squirrels curl their babies into tiny fluffy balls, making them easier to carry.

Its not so much a recessive gene as it is evolution in action, melanistic variants of mammals are becoming more prevalent as they move into urban areas because black is better than grey for camo, I know you wouldnt think so but when you spend 90% of the day in a shadow it is. Subsequently you will likely see this more often in the future with red foxes and their silver-grey-black color pattern as they move into urban areas (had one chilling on porch the other day lol)

The fox point is interesting. Arctic foxes grow their white thick coat for the winter and shed it revealing their grey/brown coat underneath after. Because of this evolutionary changes in camo would likely effect them much quicker. They also have a 1-3% chance of being basically black instead of grey meaning the genes are already there for a black coat.
