no, the only other element that closely resembles carbon according to electron shell and properties is silicon.

It's been a long time, and I can't quote the source, but as I remeber sulfur is an option for a basis for life. It has to be a very high temperature world, where the sulfur is liquid.

i'm sure they can live and evolve in a sulfur environment, actually there is a bacteria that survive in sulfur its name is green sulfur bacteria (Chlorobiaceae). They use sulfide ions as electron donor, and in the process the sulfide gets oxidized, producing globules of elemental sulfur outside the cell, which may then be further oxidized. This bacteria uses sulfur as the water is used in plants photosynthesis, to get nutrients.

No sulfur does not have the huge number of different possible conformations as carbon. silicon, is a possible, alternate material to base life forms upon.

We have sulfer in our blood (hemoglobin); otherwise that molecule is identical to chlorophyll ( the molecule of all food production, ie, photo-synthesis)!!!

no all things on this planet are carbon based and it will stay that way uless a meteor is to come and bring foriegn life forms

Sure there can be. I believe anything is possible.
