Once technology is self sustaining, the answer becomes 0. No humans will be needed for earth creatures to pursue scientific discovery.

Hm... I suppose it all hinges on what someone means by "preserving modern civilization." Does civilization being completely taken over by machines constitute "preserving" it? I can see a case either way.

But, yes, assuming we allow a civilization of machines to be consistent with "preserving modern civilization" then, you're right, the answer to the exact question asked would be zero.

Yea. If by "civilization" they mean an assortment of creatures producing goods and ideas, consuming resources, altering ecosystems and reproducing, then humans aren't required at all.

Ironically, from an economic perspective a machine civilization has a big problem: Machines are far better at creating than they are at consuming. A machine civilization might well develop into a single machine that can maintain itself. What use would a second machine be?
