The answer to this question depends on what we mean by “science.”
If we are interested in what the sciences of chemistry or physics tell us then there is very little, if anything, that is unique about humans relative to other living things on the planet. If we are interested in molecular biology, we end up in almost the same place, as there is almost nothing unique about the molecules that make us up. However, when we start to ask questions about the science of human evolution, some distinctions begin to emerge; the whole is greater than the sum of the parts.
The evolutionary history of human bodies and behavior suggests that humans cooperate, coordinate, create, destroy, imagine, believe and hope in ways that are distinctive from the rest of the world.
