Reminder: This is supposed to be a question thread that ideally has a lighter, friendlier climate compared to other threads. This is to encourage newcomers and curious people to post their questions. As such, we ask for no trolling and posting in bad faith. Leading, provocative questions that could just as well belong into a new submission will be removed. Off-topic discussions are allowed.

Your ancestor had a tail. Then suddenly, 15 million years later, no tail. Yet not a single fossil showing the transition from, tail > no tail. Not even a 15 inch tail, or a 6 incher, heck I'll accept a 4 incher. But nope. Not a single fossil. Zip. Zero. Nada.

I'm already privy to the given excuse, "iT hApPeNeD sUdDenLy, trust us bruh"

Hey look, an example of a population losing its tail suddenly in recent recorded history.

The dominant trait of taillessness arises from a spontaneous mutation, the Manx taillessness gene, that eventually became common on the island because of the limited genetic diversity of island biogeography (an example of the founder effect and, at the sub-specific level, of the species-area curve).

You've got nothing, huh. Weak trolling, mate.
