A serious question:
Which is occuring at a quicker pace (if either) -
1.) The rate at which new species are evolving into existence.
2.) The rate at which old species are becomming extinct.

If you are actually interested in this, I suggest you do some research. I guess you could try some online searches for speciation rate versus extinction rate, or try looking for articles on net diversification rate. It's a rich topic.

For large animals and plants, it is well known that at the current point in time, extinction is exceeding speciation. The stats for smaller creatures however are not known.
But these rates are very recent and are due to mans influence.

The total number of non-bacterial species in the world has been estimated at 8.7 million, with previous estimates ranging from two million to 100 million.
