    I’ll have a crack.
    What about 99%?

    100% – rounded up from 99.9% Although, given the incomplete nature of the fossil record, it’s only an estimation.

      That’s it.

      And yes, it is an estimation, but given the age of the earth and that fact that major extinctions in its history have resulted in upwards of 80% of species at the time dying, I’m willing to believe it.

      The lesson here is, everything dies, so have a drink and play trivia while you’re waiting.

    Higher or lower?

      Well answering that question would tell you the answer. (And even saying that effectively tells you the answer.)
