Sure.

If you asked Stephen J. Gould the question of "what is actually selected in natural selection?" he would have likely said the organism. In the competition in nature, when natural selection occurs, the organisms that compete the best are what are selected.

But if you asked Richard Dawkins he would say that natural selection is actually choosing the genes that are best. Since every animal has different genes (save for identical twins and other oddities) the organism is really just a survival machine for genes, which are the competing element of evolution.

Personally, I think Richard Dawkins has the most compelling and logical view point.

Other ideas have been that the species itself, and also groups (like a pack of wolves, or school of fish) are what is selected. And this is only in response to the question "What is selected?" There are hundreds of other questions in the study of evolution and unsurpisingly there is debate on which answers are the right answers.
